Killer T cells are one of the body's main lines of defense against pathogens.
Tuberculosis affects over 12 million people globally, and is usually treated with a course of four drugs over several months.
Scientists have determined how an enzyme essential for energy metabolism functions.
Millions of genetically modified mosquitoes could be released in the Florida Keys if British researchers win approval to use the bugs against two extremely painful viral diseases.
By now, most everyone has seen videos all over social media of friends and family dousing themselves in ice cold water as part of the ALS Ice Bucket Challenge.
A team of scientists based at Brown University has found that reducing expression of a fundamentally important gene called Myc significantly increased the healthy lifespan of laboratory mice, the first such finding regarding this gene in a mammalian species.
A new procedure can quickly and efficiently increase the length of human telomeres, the protective caps on the ends of chromosomes that are linked to aging and disease.
A new study has shown for the first time why protein mutations lead to the familial form of Parkinson’s disease.
The President briefly mentioned the project during the State of The Union earlier this week.
Scientists from the Florida campus of The Scripps Research Institute (TSRI) have produced an approach that protects animal models against a type of genetic disruption that causes intellectual disability, including serious memory impairments and altered anxiety levels.
Researchers at the University of California, San Diego School of Medicine, with collaborators in Korea and Scotland, have identified a novel signaling pathway critical to the immune response of cells associated with the initiation of allergic asthma.
The drugs were designed to keep cancer cells at bay by preventing their growth, survival and spread. Yet, after clinical trials, they left scientists scratching their heads and drug developers watching their investments succumb to cancer’s latest triumph.
Scientists are unraveling a mystery behind a fairly common disease that leads to heart failure: Why do some people with a key mutated gene fall ill while others stay healthy? Researchers tested more than 5,200 people to tease apart when mutations really are harmful or are just bystanders.
Fibrosis is a constant feature of all chronic liver diseases.
Researchers have found a possible predictor for little understood -- but often disabling or even fatal -- stroke complications.
When 2 milliliters of blood are run through the chip, the tumor cells stick to the nanowires like Velcro.
DNA sequences were once thought to be identical from cell to cell, but it’s increasingly understood that mutations can arise during brain development that affect only certain groups of brain cells.
For the first time, the genome of a mammal longer-lived than man has been sequenced: the bowhead whale, who lives 200-plus years, and gets far less cancer given its size.
The fingers of papillary tumors often grow back after surgery, but flat carcinoma in situ cancers are typically more aggressive and more likely to spread.
Bacteria that have evolved to help us digest the yeast that give beer and bread their bubbles could support the development of new treatments to help people fight off yeast infections and autoimmune diseases such as Crohn’s disease.
The agreement will integrate genomics research conducted at Columbia with Biogen Idec’s understanding of disease mechanisms and pathways, and expertise in discovering new medicines.
We’ve been imbibing alcohol for ten million years, and the start of that long drinking binge coincided with our descent from the trees. So alcohol may have brought us (along with lots of hangovers), some measure of our humanity.
A small protein active in the human immune response can disable bacterial toxins by exploiting a property that makes the toxins effective.
A new 12-year U.S. study shows the most frequent involve drugs used to stimulate ovaries, but it suggests problems are rarely fatal.
Some children are more sensitive to their environments, for better and for worse. Now Duke University researchers have identified a gene variant that may serve as a marker for these children, who are among society’s most vulnerable.
