Scientists have discovered that the body's own natural killer cells can suppress the immune benefits of therapeutic vaccines, a problem that can affect inoculations against chronic viral infections and cancer.

Scientists have engineered a synthetic biodegradable foam that can suppress inflammation, promote blood vessel growth and support the rapid healing of chronic skin wounds, an innovation that may one day improve treatment ...

Intriguing new research has pinpointed a special population of T cells—tissue-resident memory T cells—as key players in the development of chronic autoimmune disorders that affect the central nervous system, opening a new ...

In an unusual new study involving thousands of bacterial sequences across five continents, scientists have tracked Bordetella pertussis—the bacteria that cause whooping cough—covering the pathogen's evolution and spread worldwide ...

Tuberculosis is a major public health concern, an ancient bacterial disease that has claimed the lives of kings, presidents, poets and at least one star of Hollywood's silver screen-era. Yet even now in the 21st century, ...

Osteoarthritis is a wear-and-tear disorder marked by bone thickening and cartilage degeneration, an excruciatingly painful disability and a major cause of impaired mobility as people age. But scientists have begun viewing ...

Scientists have identified a single molecule that may explain how bacteria can trigger one of the most severe types of asthma, a discovery that for the first time identifies the "missing link" between exposure to bacterial ...

CAR T cell therapy, the breakthrough method of supercharging patients' T cells in the lab to attack cancer when re-infused, has worked more effectively against cancers of the blood than solid tumors.

Virologists thought they had seen the worst of SARS-CoV-2's variants when delta emerged in the spring of 2021, but by fall a new one was in circulation with a slew of spike protein mutations that took the scientific community ...

Immunologists in Australia have eavesdropped on a stowaway population of B cells that hide in the lungs, their telltale biomarkers indicating they're armed to fight influenza—and their presence yet another sign that the mammalian ...

Sleep may be one of the most potent medicines for the brain, scientists are discovering, as they explore the inner labyrinths of the three-pound organ during deep sleep and dream cycles in both health and disease.

Despite high remission rates for patients treated with T cells that are supercharged in laboratories into elite cancer warriors, there is still a considerable population of patients who eventually relapse, their cancers invariably ...

Some people diagnosed with HIV are able to eradicate the virus without antiretroviral medications or even stem cell transplants, possessing the ability to naturally suppress the virus and achieve a medically verifiable cure.

Even as scientists in dozens of disciplines have turned their attention to the urgent needs of the global pandemic, an elite cadre of surgeon-scientists in the United States has been focusing on a potentially deadly brain ...

New research involving a devastating genetic heart condition suggests that mutations in adhesion proteins—molecules that should support the heart—apparently play a role in disrupting the integrity of the organ's outermost ...
