The immune system is an extraordinarily complex network made up of components that simultaneously launch attacks and mount defenses.

Cross-protective antibodies from dengue and Zika last far longer than previously thought, scientists have found in a massive study involving more than 4,000 children in Nicaragua.

Two drugs approved decades ago not only counteract brain damage caused by Alzheimer's disease in animal models, the same therapeutic combination may also improve cognition.

For more than 40 years a goal that too often has proved elusive is a pharmaceutical defeat of the human immunodeficiency virus—HIV. And the thrust in recent years has emphasized bringing newer, stealthier weapons to the fight.

No aspect of SARS-CoV-2 infection has been more startling—or problematic—than the elevated risk for blood clotting, a concern that throughout the pandemic has been associated with severe COVID-19, frequently characterized ...

For decades, recipients of liver transplants have been inexplicably vulnerable to MRSA infection after their lifesaving surgeries, but the molecular mechanisms underlying that risk had remained stubbornly mystifying, at least ...

Vaccines that boost immunity against bacteria can protect the immunized from contracting drug-resistant infections, according to a team of scientists in the U.K. who also underscore that the shots can slow the spread of resistant ...

Twenty years after the 9/11 terror attacks on the United States, survivors still suffer from posttraumatic stress disorder—PTSD—a condition that New York researchers will attempt to control through bioelectronic medicine, ...

A newly discovered gene mutation linked to early onset Alzheimer's disease has been discovered by an international team of scientists, who traced the DNA flaw through multiple members of a single family.

Chronic viral infections in the liver can lead to organ dysfunction and ultimately to liver tumors in a progression invariably characterized by viruses that proliferate free of immune system restraints.

Antibodies have drawn a spotlight over the past year and a half as scientists and lay people alike have asked how long the infection-fighting proteins persist in the face of a formidable enemy—a pandemic virus that has been ...

Just as it is for marathoners who've completed a 26-mile run, or shrubs that have gone without water in a heatwave—exhaustion is an unavoidable fact of life. Dogs get exhausted after herding sheep; birds turn in for the night ...

With a global focus on strategies to curb expansion of a fast-moving coronavirus pandemic, the question again has arisen: What more is being done about HIV, a scourge that has lasted more than 40 years—is a cure finally in ...

Quick, accurate and easy-to-use, CRISPR-Cas9 has made genomic editing more efficient—but at the same time has made human germline editing much more feasible, erasing many of the ethical barriers erected to prevent scientists ...

The molecular world is full of surprises, and none more stunning than those occurring among the infinitesimal proteins that drive the activities guarding against viral infections and cancer.
