"It only takes one virus to get through for a person to be infected," explained Dr. John Mascola. This is true of any viral infection, but in this instance, Mascola is referring to HIV and his ongoing efforts to develop a vaccine against the virus. "It's been so difficult to make an HIV/AIDS vaccine."

Those were the words of many working in HIV vaccine development until the results of a 2009 trial in Thailand surprised everyone. "The field is energized," said Mascola, director of the Vaccine Research Center at the U.S. National Institute of Allergy and Infectious Diseases, describing the change in atmosphere in the vaccine community.

The trial included over 16,000 volunteers and was the largest clinical trial ever conducted for a vaccine against HIV. It was also the first to show any protection at all against infection.

Two previously developed vaccines, known as ALVAC-HIV and AIDSVAX, were used in combination, with the first priming an immune response against HIV and the second used as a booster once the immunity waned. The duo reduced the risk of contracting HIV by 31.2% -- a modest reduction, but it was a start.

To date, only four vaccines have made it as far as testing for efficacy to identify their levels of protection against HIV. Only this one showed any protection.

"That trial was pivotal," Mascola said. "Prior to that, it wasn't known whether a vaccine could be possible."

In recent years, there have been parallel findings of an equally pivotal nature in the field of HIV prevention, including the discovery that people regularly taking their antiretroviral treatment reduce their chances of spreading HIV by 96% and that men who are circumcised reduce their risk of becoming infected heterosexually by approximately 60%.

Both improved access to antiretrovirals and campaigns to increase male circumcision in high-risk populations have taken place since the discoveries, and although numbers of new infections are falling, they're not falling fast enough.

In 2013, there were 35 million people estimated to be living with HIV globally. There were still 2.1 million new infections in 2013, and for every person who began treatment for HIV last year, 1.3 people were newly infected with the lifelong virus, according to UNAIDS. A vaccine remains essential to control the epidemic.

A complex beast

Scientists like Mascola have dedicated their careers to finding a vaccine, and their road has been tough due to the inherently complicated nature of the virus, its aptitude for mutating and changing constantly to evade immune attack, and its ability attack the very immune cells that should block it.

There are nine subtypes of HIV circulating in different populations around the world, according to the World Health Organization, and once inside the body, the virus can change continuously.

"Within an individual, you have millions of variants," explained Dr. Wayne Koff, chief scientific officer for the International AIDS Vaccine Alliance.

HIV invades the body by attaching to, and killing, CD4 cells in the immune system. These cells are needed to send signals for other cells to generate antibodies against viruses such as HIV, and destroying those enables HIV to cause chronic lifelong infections in those affected.

Measles, polio, tetanus, whooping cough -- to name a few -- all have vaccines readily available to protect from their potentially fatal infections. But their biology is seemingly simple in comparison with HIV.

"For the older ones, you identify the virus, either inactivate it or weaken it, and inject it," Koff said. "You trick the body into thinking it is infected with the actual virus, and when you're exposed, you mount a robust immune response."

This is the premise of all vaccines, but the changeability of HIV means the target is constantly changing. A new route is needed, and the true biology of the virus needs to be understood. "In the case of HIV, the old empirical approach isn't going to work," Koff said.

Scientists have identified conserved regions of the virus that don't change as readily, making them prime targets for attack by antibodies. When the success of the Thai trial was studied deep down at the molecular level, the protection seemed to come down to attacking some of these conserved regions. Now it's time to step it up.

In January, the mild success in Thailand will be applied in South Africa, where over 19% of the adult population is living with HIV. The country is second only to bordering Swaziland for having the highest rates of HIV in the world.

"The Thai vaccine was made for strains (of HIV) circulating in Thailand," said Dr. Larry Corey, principal investigator for the HIV Vaccine Trials Network, which is leading the next trial in South Africa. The strain, or subtype, in this case was subtype B. "For South Africa, we've formed a strain with common features to (that) circulating in the population." This region of the world has subtype C.

An additional component, known as an adjuvant, is being added to the mix to stimulate a stronger and hopefully longer-lasting level of immunity. "We know durability in the Thai trial waned," Corey said. If safety trials go well in 2015, larger trials for the protective effect will take place the following year. An ideal vaccine would provide lifelong protection, or at least for a decade, as with the yellow fever vaccine.

A broad attack

The excitement now reinvigorating researchers stems not only from a modestly successful trial but from recent successes in the lab and even from HIV patients themselves.

Some people with HIV naturally produce antibodies that are effective in attacking the HIV virus in many of its forms. Given the great variability of HIV, any means of attacking these conserved parts of the virus will be treasured and the new found gold comes in the form of these antibodies -- known as "broadly neutralizing antibodies." Scientists including Koff set out to identify these antibodies and discover whether they bind to the outer coat of the virus.

The outer envelope, or protein coat, of HIV is what the virus uses to attach to, and enter, cells inside the body. These same coat proteins are what vaccine developers would like our antibodies to attack, in order to prevent the virus from entering our cells. "Broadly neutralizing antibodies" could hold the key because, as their name suggests, they have a broad remit and can attack many subtypes of HIV. "We will have found the Achilles heel of HIV," Koff said.

Out of 1,800 people infected with HIV, Koff and his team found that 10% formed any of these antibodies and just 1% had extremely broad and potent antibodies against HIV. "We called them the elite neutralizers," he said of the latter group. The problem, however, is that these antibodies form too late, when people are already infected. In fact, they usually only form a while after infection. The goal for vaccine teams is to get the body making these ahead of infection.

"We want the antibodies in advance of exposure to HIV," explained Koff. The way to do this goes back to basics: tricking the body into thinking it is infected.

"We can start to make vaccines that are very close mimics of the virus itself," Mascola said.

Teams at his research center have gained detailed insight into the structure of HIV in recent years, particularly the outer coat, where all the action takes place. Synthesizing just the outer coat of a virus in the lab and injecting this into humans as a vaccine could "cause enough of an immune response against a range of types of HIV," Mascola said.

The vaccine would not contain the virus itself, or any of its genetic material, meaning those receiving it have no risk of contracting HIV. But for now, this new area remains just that: new. "We need results in humans," Mascola said.

Rounds of development, safety testing and then formal testing in high-risk populations are needed, but if it goes well, "in 10 years, there could be a first-generation vaccine." If improved protection is seen in South Africa, a first-generation vaccine could be with us sooner.

Making an Impact

When creating vaccines, the desired level of protection is usually 80% to 90%. But the high burden of HIV and potentially beneficial impact of lower levels of protection warrant licensing at a lower percentage.

"Over 50% is worth licensing from a public health perspective," Koff said, meaning that despite less shielding from any contact with the HIV virus, even a partially effective vaccine would save many lives over time.

The next generations will incorporate further advancements, such as inducing neutralizing antibodies, to try to increase protection up to the 80% or 90% desired.

"That's the history of vaccine research; you develop it over time," Corey said. He has worked in the field for over 25 years and has felt the struggle. "I didn't think it would be this long or this hard ... but it's been interesting," he ponders.

But there is light at the end of tunnel. Just.

"There has been no virus controlled without a vaccine," he concluded when explaining why, despite antiretrovirals, circumcision and increased awareness, the need for a one-off intervention like a vaccine remains strong.

"Most people that transmit it don't even know they have it," he said. "To get that epidemic, to say you've controlled it, requires vaccination."

Amyotrophic lateral sclerosis - also known as Lou Gehrig's disease - is a condition that gradually attacks nerve cells that control our voluntary movement, leading to paralysis and death. In the US, a reported 30,000 individuals are living with the disease, but now, scientists have identified a fault in protein formation, which could be the origin of this condition.

The researchers, from the University of Wisconsin-Madison, have published their study on amyotrophic lateral sclerosis (ALS) in the journal Cell Stem Cell.

According to the Centers for Disease Control and Prevention (CDC), nobody knows for sure why ALS occurs, and there is currently no cure.

The researchers of this latest study, led by Su-Chun Zhang, senior author and neuroscientist at UW-Madison, say previously, a genetic mutation was discovered in a small group of patients with ALS, prompting scientists to transfer that gene to animals for drug treatment testing. 

However, this approach has not yet worked. As such, Zhang and his team decided to study diseased human cells - called motor neurons - in lab dishes. These motor neurons are what direct muscles to contract, and Zhang explains this is where failures occur in ALS.

Discovery centers on faulty proteins inside motor neurons

Zhang was the first scientist to ever grow motor neurons from human embryonic stem cells around 10 years ago, and he has recently been transforming skin cells into induced pluripotent stem (iPS) cells, which are then transformed into motor neurons.

He explains that the iPS cells can be used as models for disease since they have many of the same characteristics as their donor cells.

"With iPS, you can take a cell from any patient, and grow up motor neurons that have ALS," Zhang explains. "That offers a new way to look at the basic disease pathology."

For their latest study, the researchers have focused on proteins that erect a transport structure - called a neurofilament - inside the motor neurons.

They say the neurofilament moves chemicals and cellular parts - including neurotransmitters - to far sides of the nerve cell. 

Zhang explains that the motor neurons, for example, that control foot muscles are around 3 ft long, so they need to be moved a whole yard from the cell body to the spot where they can signal the muscles.

As such, one of the first signs of ALS in a patient who lacks this connection is paralysis of the feet and legs.

'Findings have implications for other neurodegenerative disorders'

Before now, scientists have understood that with ALS, so-called tangles - misshapen protein - along the nerve's paths block the route along the nerve fibers, which eventually results in the nerve fiber malfunctioning and dying.

The team's recent discovery, however, has to do with the source of these tangles, which lies in a shortage of one of three proteins in the neurofilament.

Zhang explains that the neurofilament plays both a structural and a functional role:

"Like the studs, joists and rafters of a house, the neurofilament is the backbone of the cell, but it's constantly changing. These proteins need to be shipped from the cell body, where they are produced, to the most distant part, and then be shipped back for recycling.

If the proteins cannot form correctly and be transported easily, they form tangles that cause a cascade of problems."

He says their discovery is that the origin of ALS is "misregulation of one step in the production of the neurofilament."

Additionally, he notes that similar tangles crop up with Alzheimer's and Parkinson's diseases: "We got really excited at the idea that when you study ALS, you may be looking at the root of many neurodegenerative disorders."

Zhang and his team also observed that this misregulation happens very early, which is why it is highly likely that what they found is the origin ALS.

"Nobody knew this before, but we think if you can target this early step in pathology, you can potentially rescue the nerve cell," he says.

And as if this discovery is not exciting enough, the team also found a way to rescue the neural cells in the lab dishes, and when they "edited" the gene that orchestrates formation of the blundered protein, they found that the cells suddenly looked normal.

They report that they are currently testing a wide range of potential drugs, which brings hope to the domain of ALS research.

The CDC have a National ALS Registry, where patients with the condition can complete brief risk-factor surveys to help scientists defeat ALS.

The current measles vaccine - administered by an injection - is effective and safe, but experts say coverage could be made better by a vaccine that is easier to administer and transport. Now, a measles vaccine consisting of dry powder that is delivered with a puff of air has proven safe in early human trials and effective in previous animal trials.

Though many people living in the US consider measlesto be a thing of the past - thanks, in large part, to widespread vaccination efforts - the disease has made a comeback in recent years. 

In fact, 2014 has so far seen a record number of measles cases in the US, with 603 confirmed cases reported to the Centers for Disease Control and Prevention's (CDC) National Center for Immunization and Respiratory Diseases (NCIRD) between January 1st and October 31st.

The organization says this is the highest number of cases since measles elimination was confirmed in the US in 2000.

Measles is spread by droplets or direct contact with the nose or throat secretions of people who are infected, but it can also be spread through the air or by objects containing nose and throat secretions.

According to the World Health Organization (WHO), measles is "one of the most readily transmitted communicable diseases and probably the best known and most deadly of all childhood rash/fever illnesses."

In 2013, the disease killed 145,700 people worldwide - most of whom were children - despite an already existing effective injectable vaccine.

"Delivering vaccines in the conventional way, with needle injections, poses some serious challenges, especially in resource-poor parts of the world," says Prof. Robert Sievers, author of the latest study from the University of Colorado Boulder's Department of Chemistry and Biochemistry.

New vaccine safe, with evidence of positive immune response

To improve the delivery of the vaccine, Prof. Sievers and his colleagues created a dry delivery technique - that involves an inhalable, dry powder - in order to circumvent the need for injections and liquid storage, and to avoid risk of vaccine contamination.

In previous work, he and his team showed that their vaccine protected rhesus macaques and cotton rats from measles infection, and they also demonstrated that their dry vaccines can be safely stored for 6 months to 4 years at room temperature or in refrigerators kept at 36-46° F (2-8°C).

But their latest study heralds the success of the first phase 1 clinical trial for their vaccine in humans. "Out of an abundance of caution," says Prof. Sievers, "we test first in people who have already had the disease, or been injected earlier by needles with liquid vaccines."

As such, they enrolled 60 adult males aged 18-45 years who were already seropositive for the measles antibody. In the clinical trial, the researchers tested delivery of the powder using two devices and compared those two groups with a group that received the typical injection.

Results showed that the men from all three groups responded similarly and displayed no clinically relevant side effects. What is more, there was also evidence of a positive immune response to vaccination from the powder.

Any adverse events were recorded with diary cards for 28 days after the vaccination, and researchers followed the participants for 180 days post-vaccination to watch for any long-term adverse events. Additionally, the team measured measles antibodies 7 days before vaccination and 21 and 77 days after vaccination.

Commenting on their new dry vaccine, Prof. Sievers says:

"You don't need to worry about needles; you don't need to worry about reconstituting vaccines with clean water; you don't need to worry about disposal of sharps waste or other vaccine wastage issues; and dry delivery is cheaper."

Vaccine trials in humans are ongoing

Though their trial demonstrated that their powder vaccine is safe, because the men were already immune to measles, it could not compare effectiveness of the vaccines.

"It is very good news that we encountered no problems," says Prof. Sievers, "and now we can move on."

He and his team plan to continue their research through phase 2 and 3 trials in people who are not yet immune to measles, including women and children.

The research was funded by a $20 million grant from the Foundation for the National Institutes of Health, with support from the Bill and Melinda Gates Foundation. It should be noted that the authors of the paper include researchers from the Serum Institute of India, Ltd. - the largest manufacturer of childhood vaccines used in developing countries.

Additionally, Prof. Sievers is president and CEO of Aktiv-Dry, LLC, a Colorado-based company that provides dry powder solutions for the vaccine, pharmaceutical and biotechnology industries.

A number of eye conditions can be treated by administering drugs directly into the eye. Yet, conventional needles have a bunch of drawbacks, including the patients’ fear of needles entering such fragile parts of the body and the difficulty of accurately administering medication into a targeted region of the eye. For glaucoma, for example, eye drops are prescribed which have a shorter active lifetime and are often skipped by the patients. An easy injection that works for months at a time would help control the disease considerably better.

Researchers at Georgia Tech and Emory University have been working on microneedles and formulations to safely and effectively deliver drugs into the eye. The microneedles are designed to only penetrate to the correct depth and the formulations need to be viscous enough to stay in place and release their therapeutic compounds in a controlled fashion. The researchers have already tested the microneedles on laboratory animals and showed that they can place drugs within the targeted sections of the eye.

More from Georgia Tech:

The microneedle therapy would inject drugs into space between two layers of the eye near the ciliary body, which produces the aqueous humor. The drug is retained near the injection side because it is formulated for increased viscosity. In studies with an animal model, the researchers were able to reduce intraocular pressure through the injections, showing that their drug got to the proper location in the eye.

Because the injection narrowly targets delivery of the drug, researchers were able to bring about a pressure reduction by using just one percent of the amount of drug required to produce a similar decline with eye drops.

To treat corneal neovascularization, the researchers took a different approach, coating solid microneedles with an antibody-based drug that prevents the growth of blood vessels. They inserted the coated needles near the point of an injury, keeping them in place for approximately one minute until the drug dissolved into the cornea.

In an animal model, placement of the drug halted the growth of unwanted blood vessels for about two weeks after a single application.

Many people have been told, incorrectly, that they're allergic to penicillin, but have not had allergy testing. These people are often given alternative antibiotics prior to surgery to ward off infection. But when antibiotic choices are limited due to resistance, treatment alternatives may be more toxic, more expensive and less effective.

According to two studies presented at the American College of Allergy, Asthma and Immunology (ACAAI) Annual Scientific Meeting, people who believe they have a penicillin allergy would benefit from consultation from an allergist and penicillin allergy skin testing. Once they know if they are allergic, they can be given appropriate -- and not more resistant -- treatment prior to surgery. Of the 384 people in the first study who believed they were allergic to penicillin, 94 percent tested negative for penicillin allergy.

"A large number of people in our study who had a history of penicillin allergy were actually not allergic," said allergist and ACAAI member Thanai Pongdee, MD, lead study author. "They may have had an unfavorable response to penicillin at some point in the past, such as hives or swelling, but they did not demonstrate any evidence of penicillin allergy at the current time. With that in mind, their doctors prescribed different medications prior to surgery."

In the second study, 38 people who believed they were allergic to penicillin were given penicillin skin testing to see if it was possible to help reduce the use of high-cost antibiotics. Of the 38 people tested, all of them tested negative to an allergy for penicillin. Once it was known they weren't allergic to penicillin, the medical center was able to change the medications of 29 of the patients, thereby significantly lowering prescription costs.

"When you are told you have an allergy to something, it's important to be seen and tested by an allergist, who has the specialized training needed for accurate diagnosis and treatment," said allergist James Sublett, ACAAI president-elect. "If you're truly allergic to a medication, your allergist will counsel you on an appropriate substitute."

It is well known that exercise is good for the mind and body, but to what extent does the neighborhood or community in which we live affect our physical and mental health? New research from the University of Kansas suggests the walkability of a community has a great impact on cognition in older adults.

Previous studies have detailed the importance physical exercise has for executive function in older adults.

But how can the layout of a neighborhood encourage its residents to get out and walk? This is precisely what Amber Watts, assistant professor of clinical psychology at the University of Kansas, wanted to find out.

"Depending on which type of walking [leisure vs. walking to get somewhere] you're interested in, a neighborhood might have different characteristics," she says. "Features of a neighborhood that encourage walking for transportation require having someplace worth walking to, like neighbors' houses, stores and parks."

She adds that neighborhoods that encourage leisure walking have "pleasant things to look at," including walking trails and trees, and they should feel safe.

Her research, which she presented yesterday at the Gerontological Society of America's annual meeting in Washington, DC, suggests that neighborhoods that encourage walking can protect against cognitive decline in older adults.

To conduct her research, Watts used geographic information systems (GIS) to judge walkability. This involved maps that measure and analyze spatial data.

Better physical and mental health

Detailing how she collected her data, Watts explains:

"GIS data can tell us about roads, sidewalks, elevation, terrain, distances between locations and a variety of other pieces of information. We then use a process called space syntax to measure these features, including the number of intersections, distances between places or connections between a person's home and other possible destinations they might walk to."

She also looked at how complicated a route is from one location to another: "For example, is it a straight line from point A to point B, or does it require a lot of turns to get there?"

To conduct the study, Watts and colleagues tracked 25 people with mild Alzheimer's disease and 39 older adults without any cognitive impairment. Using the space syntax data, they created a "walkability score" for the participants' home addresses.

Then, they estimated the relationship between a person's neighborhood scores and how well they performed on cognitive tests over 2 years. The cognitive tests included three categories: attention, verbal memory and mental status. The team also factored in issues that might influence cognitive scores, including age, gender, education and wealth.

Results from the study suggest that communities that are easier to walk in are linked to better physical health outcomes - such as lower body mass and blood pressure - and cognition - including better memory.

Watts and her colleagues believe their findings could benefit older adults, health care professionals, caregivers and even architects and urban planners.

Do mentally complex neighborhoods act like a brain-training game?

Though elaborate community layouts may be expected to confuse older residents, Watts and her team found that they actually serve to keep cognition sharp.

"There seems to be a component of a person's mental representation of the spatial environment, for example, the ability to picture the streets like a mental map," Watts says.

She adds that complicated environments may demand more intricate mental processes in order to navigate them, which could keep the mind sharp. This is in line with previous studies, which have demonstrated how staying mentally active helps to preserve memory.

"Our findings suggest that people with neighborhoods that require more mental complexity actually experience less decline in their mental functioning over time," Watts adds.

She explains that a challenging environment keeps an individual's body and mind healthy:


"With regard to the complexity of neighborhood street layouts - for example, the number of turns required getting from point A to point B - our results demonstrate that more complex neighborhoods are associated with preserved cognitive performance over time.


We think this may be because mental challenges are good for us. They keep us active and working at that optimal level instead of choosing the path of least resistance."

A National Institute on Aging grant, KU Strategic Initiative Grant and Frontiers Clinical Translational Science award helped fund the study.

Residents of the southern United States may be at risk for a parasitic infection that can lead to severe heart disease and death, three new studies suggest.

Chagas disease, which is transmitted by "kissing bugs" that feed on the faces of humans at night, was once thought limited to Mexico, Central America and South America.

That's no longer the case, the new research shows.

"We are finding new evidence that locally acquired human transmission is occurring in Texas," said Melissa Nolan Garcia, a research associate at Baylor College of Medicine in Houston and the lead author of two of the three studies.

Garcia is concerned that the number of infected people in the United States is growing and far exceeds the U.S. Centers for Disease Control and Prevention's estimate of 300,000.

In one pilot study, her team looked at 17 blood donors in Texas who tested positive for the parasite that causes Chagas disease.

"We were surprised to find that 36 percent had evidence of being a locally acquired case," she said. "Additionally, 41 percent of this presumably healthy blood donor population had heart abnormalities consistent with Chagas cardiac disease."

The CDC, however, still believes most people with the disease in the United States were infected in Mexico, Central and South America, said Dr. Susan Montgomery, of the agency's parasitic diseases branch.

"There have been a few reports of people becoming infected with these bugs here in the United States," she said. "We don't know how often that is happening because there may be cases that are undiagnosed, since many doctors would not think to test their patients for this disease. However, we believe the risk of infection is very low."

Maybe so, but kissing bugs -- blood-sucking insects called triatomine bugs -- are found across the lower half of the United States, according to the CDC. The insects feed on animals and people at night.

The feces of infected bugs contains the parasite Trypanosoma cruzi, which can enter the body through breaks in the skin. Chagas disease can also be transmitted through blood.

It's a silent killer, Garcia said. People don't feel sick, so they don't seek care, but it causes heart disease in about 30 percent of those who get infected, she said.

In another study, Garcia's team collected 40 insects in 11 Texas counties. They found that 73 percent carried the parasite and half of those had bitten humans as well as other animals, such as dogs, rabbits and raccoons.

A third study found that most people infected with Chagas aren't treated.

For that project, Dr. Jennifer Manne-Goehler, a clinical fellow at Harvard Medical School and Beth Israel Deaconess Medical Center in Boston, collected data on nearly 2,000 people whose blood tested positive for Chagas.

Her team found that only 422 doses of medication for the infection were given by the CDC from 2007 to 2013. "This highlights an enormous treatment gap," Manne-Goehler said in a news release.

The findings of all three studies, published recently in the American Journal of Tropical Medicine and Hygiene, were to be presented Tuesday in New Orleans at the annual meeting of the American Society of Tropical Medicine and Hygiene.

Symptoms of Chagas can range from none to severe with fever, fatigue, body aches and serious cardiac and intestinal complications.

"Physicians should consider Chagas when patients have swelling and enlargement of the heart not caused by high blood pressure, diabetes or other causes, even if they do not have a history of travel," Garcia said.

However, the two treatments for this disease are "only available [in the United States] via an investigative drug protocol regulated by the CDC," Garcia said. They are not yet approved by the Food and Drug Administration.

Efforts are under way to develop other treatments for Chagas disease, Montgomery said.

"Several groups have made some exciting progress in drug development," she said, "but none have reached the point where they can be used to treat patients in regular clinical practice."
