Roseolovirus infection disrupts how the body trains immune cells not to attack it, a mouse study shows.

A study identifies a gene that appears to be partially responsible for the health effects of a limited diet.

When coated with positively charged particles, the bacteria shuttled antigens out of tumors and activated the immune system, a study finds.

Specialized immune cells generated in vivo reduce cardiac scar tissue in mice, a new study shows.

Researchers report what appears to be the second case of a person’s immune system clearing the virus on its own.

It’s unclear whether differing odds of dying between men and women reflect inherent differences between male and female immune systems or differences rooted in gender norms.

More than a dozen vaccines for tuberculosis are currently being tested in clinical trials. Some use whole bacteria as BCG does, while others deliver protein subunits or genetic material carried by viral vectors.  

This month marks the 100-year anniversary of BCG, still the only approved vaccine against the lethal pathogen. But there are new vaccines for this wily foe on the horizon.

Researchers identify live bacteria in fetal guts, skin, lungs, and placentas that activate memory T cells, indicating that early exposure to microbes could help educate the developing immune system.

Scientists use a protein found in mucus membranes to ferry vaccines to the lymph nodes.

Rheumatologist Song Guo Zheng pleaded guilty in November to delivering US-funded research to China.

Death rates among blood cancer patients who contract COVID-19 are higher than for those with other cancers, pointing to impaired immunity that makes it hard to overcome the virus.

Outcomes in COVID-19 patients may be better in those recently infected with endemic coronaviruses.
