Deep in the folds of the intestine, in microscopic pockets called crypts, a quiet surveillance system is always at work. Stem cells lining the gut wall are not just rebuilding tissue—they are listening and signaling. When ...

Across the spectrum of human afflictions—from cancer to heart disease to rare genetic conditions—medical investigators are continually attempting to break new ground by developing better methods of treating patients. It is ...

Cancer drug resistance is the devastating reason that treatments fail and cancers metastasize, spreading to distant sites seeding new resistant tumors elsewhere in the body.

Despite the capability of antiretroviral drugs to suppress HIV to undetectable levels, some people living with the human immunodeficiency virus can't reach the goal of viral imperceptibility even with daily doses of the potent ...

Scientists have demonstrated for the first time how Staphylococcus aureus—a leading cause of skin infections—reshapes the immune system's inflammatory responses in children with a rare skin condition.

Late in the Middle Ages, Italian stargazers gave a name to the annual contagion that rolled around each year like clockwork. It was a name that stuck, and to this day is known as influenza.

To undergo kidney dialysis, doctors must first surgically create an access route—an arteriovenous fistula—usually in an arm, a conduit that will accommodate hemodialysis treatments. It is a routine outpatient procedure performed ...

After the advent of antibiotics in the 1940s, scientists were certain that they were on the cusp of conquering infectious diseases, their confidence bolstered by the notion that a comprehensive knowledge of bacterial pathogens ...

Antibiotics are the old medicine cabinet standby for treating infections caused by multidrug-resistant Staphylococcus aureus, but as antimicrobial resistance continues to mount globally, scientists say there's a need for ...

An evolving form of therapy to treat devastating neurodegenerative disorders by injecting fresh immune cells—microglia—directly into the brain, promises a new lease on health by slowing the progression of mind-robbing conditions.

The cancer drugs called PARP inhibitors have a puzzling reputation: even though they are treatment mainstays for multiple forms of cancer, they can damage cancer-killing T cells and disrupt the potential for meaningful therapy. ...

Enzymes known as kinases play a critical role in cell growth, metabolism and signaling in a multitude of organisms across the tree of life—from algae to helminths to mammals. Now, scientists have developed an atlas of bacterial ...

Assessing the distribution of a medication in the brain is critical for the treatment of a vast range of neurological disorders, especially conditions such as Parkinson's and Alzheimer's diseases. To that end, scientists ...

Monoclonal antibodies provide protection against a wide range of infectious microbes, and now, in a series of elegant laboratory experiments, scientists have uncovered how a pair of these lab-engineered molecules fight malaria.

Obesity can have a distinct impact on the absorption, effectiveness and excretion of antibiotics, medications that have been in use for more than 80 years, but only now have consensus guidelines been proposed on prescribing ...
