News: Turning Off the Immune System May Turn on Protection Against HIV
Even though HIV rates declined 18% between 2008 and 2014, 1.1 million people in the US are living with the infection. Part of that is because HIV is treatable, but not curable.

A vaccine against HIV might prevent the disease that we can't seem to cure. Some HIV patients make antibodies that can take down the virus, much the way a vaccine might. But, scientists haven't been able to provoke that type of response in other people. However, in a process that might work in humans, a group of researchers has successfully generated antibodies in cows that neutralize multiple strains of HIV.
Type 1 diabetes is an attack on the body by the immune system — the body produces antibodies that attack insulin-secreting cells in the pancreas. Doctors often diagnose this type of diabetes in childhood and early adulthood. The trigger that causes the body to attack itself has been elusive; but many research studies have suggested viruses could be the root. The latest links that viruses that live in our intestines may yield clues as to which children might develop type 1 diabetes.
The herpes simplex virus (HSV) can cause devastating complications for infected newborns whose mothers have genital herpes. Understanding risk and research can help you, and your baby, when the time comes.
The problem with HIV is that it attacks and kills the very cells of the immune system that are supposed to protect us from infections — white blood cells. But a new technique, developed by scientists at The Scripps Research Institute (TSRI) in La Jolla, California, offers a distinct HIV-killing advantage.
As summer mosquito season approaches, researchers are warning people with previous exposure to West Nile virus to take extra precautions against Zika. A new study found that animals with antibodies to West Nile in their blood have more dangerous infections with Zika than they would normally.
Flu vaccines can help prevent us from getting or suffering the most severe effects of the flu. But, each vaccine only protects us from three different strains of the flu. If we don't have a vaccine against all types of flu, it leaves us open for an epidemic with a flu virus we didn't expect.
Even though the Ebola virus was discovered as recently as 1976, over 30,000 people have been infected since, and half have died a horrible death. Since there's no way to cure the infection, the world desperately needs a way to prevent it — and the five similar viruses in its family, the ebolaviruses.
A young child becomes very thirsty very often and seems tired all the time. A visit to the pediatrician determines she has type 1 diabetes. The onset of type 1 diabetes may seem sudden, and it can be, but the disease may actually have been triggered by common childhood viruses years earlier.
Heart disease is the leading cause of death of men and women in the US. Over half a million Americans die from it annually. Atherosclerosis — a build up of plaque in the arteries — is a common feature of heart disease and can be caused by smoking, fats and cholesterol in the blood, diabetes, and high blood pressure.
Alzheimer's disease — an irreversible, progressive brain disorder — is the sixth leading cause of death in the US and more than afflicts 5 million Americans. As if those numbers aren't scary enough, the Centers for Disease Control and Prevention expect that number to nearly triple by 2050.
Drug-resistant bacteria have made curing some infections challenging, if not nearly impossible. By 2050, it's estimated that 10 million people will be dying annually from infections with antibiotic-resistant organisms.
As if the swollen, painful joints of rheumatoid arthritis weren't enough, the disease is the result of our immune system turning against cells of our own body. Ever since this realization, scientists have worked to find the trigger that sets the immune system off. Scientists believe that gut bacteria may have a role in initiating the abnormal immune response. Now, a team of researchers from Boston has figured out how that might occur.
This how to video shows how to fight a cold naturally or how to get over an infection. When you get a cold, there is an imbalance with your blood PH or an outside invader such as a virus. Some tips to get yourself feeling better are to boost your immune system with herbal supplements and getting a good source of protein. Protein helps to form antibodies, and without a good source of protein your body loses that source of protection. This video shows that the best source of protein is meat and...
The culprit probably wasn't what doctors were expecting when a 57-year-old man in Hong Kong came to the hospital. The patient was admitted to the intensive care unit in critical condition. A clue to the cause of the infection would lie in the man's profession—he was a butcher.
A new study has found that up to half of people who think they have a penicillin "allergy" can still receive the drug, and other antibiotics with similar structures, without any negative reactions to the meds. Why? Because they're not really allergic, doctors say.
All fields of study have their own language. For people interested in learning about microbes, the language can sometimes be downright difficult — but it doesn't need to be. From antibiotics to xerophiles, we have you covered in an easy-to-understand glossary.
A recent study offers information that might help combat a deadly virus that affects an estimated 300,000 people each year in West Africa.
Pertussis, or whooping cough, is a highly contagious disease that can be life-threatening for young children. New research backs a recommendation that all pregnant women receive a pertussis booster with each pregnancy, as it can help their infants fight off the infection.
Maternal infection with genital herpes, or other pathogens, during early pregnancy could increase risk of autism, or other neurodevelopmental disorders, says a new study.
So cute, so furry, and so chock full of parasites. While raccoons are fun to watch, they are neither friendly nor clean — and they can make you sick in more ways than one.
Obstetric tetanus in an unvaccinated Amish woman after a home birth has emphasized the need for preventative healthcare.
Lyme is a growing threat as we move into warmer weather in the US. Researchers have said this year could be one of the worst for this tick-borne disease, as a skyrocketing mouse population and warmer temperatures increase the risk.
Viral infections have been the focus of attention in the development of autoimmune diseases—diseases where the body's immune system reacts to the body's own cells—because they trigger the immune system into action.
Infections with group A streptococcus, like Streptococcus pyogenes, claim over a half million lives a year globally, with about 163,000 due to invasive strep infections, like flesh-eating necrotizing fasciitis and streptococcal toxic shock syndrome.
As deeply as smartphones are integrated into our daily lives, it's no surprise that people are finding ways to use them to stay healthy. From detecting cancer and radiation to diagnosing STDs, phones have come a long way, baby.
Andre was enjoying the carefree life of a 12-year-old with his friends, riding his bike and playing sports, like all kids that age. Schoolwork wasn't hard for him, and his grades showed that.
The Centers for Disease Control and Prevention (CDC) just reported some upsettingly high numbers of human papillomavirus (HPV) in adults. In data retrieved from 2013–2014, 22.7% of US adults in the 18–59 range were found to have the types of high-risk genital HPV that cause certain cancers.
An older man dies of Zika. A younger man who cares for him catches Zika — but doctors cannot pinpoint how the disease was transmitted. While proximity to the patient is sufficient explanation for the rest of us, for microbe hunters, it is a medical mystery. Why? Zika is not known to transmit from person-to-person casually.
Most of us have already had an encounter with the Epstein-Barr virus, or EBV, for short. As part of the herpes family, it's one of the most common disease-causing viruses in humans. We get the disease with (or without) some nasty symptoms, then we recover. However, EBV stays in our body after the illness has ended, and it's one of the few viruses known to cause cancer.
Breastfeeding is the ultimate in farm-to-table dining. It is sustenance prepared just for the baby and delivered with a very personal touch. Along with bonding, breastfeeding provides powerful protection to infants and young children in the form of beneficial bacteria, hormones, vitamins, protein, sugar, and antibodies manufactured on site to support infant health.
When just floating peacefully in the water with their brood mates, the Culex mosquito larvae in the image above does not look very frightening. But in their adult form, they are the prime vector for spreading West Nile virus — a sometimes mild, sometimes fatal disease.
Phase 2 of a Zika vaccine trial began in the United States this week, along with Central and South America.
Tremendous strides have been made in the treatment and outlook for patients infected with HIV, the human immunodeficiency virus. Treatment with a combination of antiretroviral drugs can keep patients with HIV alive for decades, without symptoms of the infection. The trouble is, if HIV-infected people stop taking their medications, the virus takes over in full force again—because the virus hides out quietly in cells of the immune system, kept in check, but not killed by the treatment.
Every year, 100-200 people in the US contract leptospirosis, but usually 50% of the cases occur in Hawaii where outdoor adventurers are exposed to Leptospira bacteria found in freshwater ponds, waterfalls, streams, and mud. That's why it's so alarming that two people in the Bronx have been diagnosed with the disease and a 30-year-old man has died from it.
You know the signs—sneezing, fever, nagging cough, no energy, no appetite. It's the flu, but this time, it's your dog who's down and out. Yes, dogs get the flu, too. However, a team from the University of Rochester Medical Center and their collaborators have developed a new vaccine that may make the doggy flu a thing of the past.
You might feel the bite, you might not, but an infected mosquito has injected you with a parasite named Plasmodium falciparum, a single-cell protozoa that quickly takes up residence in your body.
The story of Helicobacter pylori is a real testament to the tenacity of medical researchers to prove their hypothesis. It took decades before the scientific world would accept that the bacteria H. pylori caused ulcers.
When Kaci Hickox, a Doctors Without Borders nurse, returned to New Jersey from working with Ebola patients in West Africa in 2014, she was surprised by her reception. Instead of a quiet return to her home in Maine after four weeks on the front line of Ebola treatment, she was quarantined by the State of New Jersey in Newark. She later filed a lawsuit in U.S. District Court for violation of her civil rights, false imprisonment, and invasion of privacy.
There are all kinds of theories—many supported by science—about what causes Alzheimer's disease. Tangles of protein called ß-amyloid (pronounced beta amyloid) plaques are prominently on the list of possible causes or, at least, contributors. An emerging theory of the disease suggests that those plaques aren't the problem, but are actually our brains' defenders. They show up to help fight an infection, and decades later, they become the problem.
