Infusions of donor T cells to fight the cancer often fail, but sodium bicarbonate can counter lactic acid produced by leukemia cells, potentially improving remission rates in mice and humans.

A recent study elucidates some of the changes that occur in the body after inoculation with a tuberculosis vaccine.

Bat species use different strategies to dampen immune activation in response to viruses.

Recent data show that the drug bamlanivimab, also known as LY-CoV555, does not appear to help those with severe cases of COVID-19, but trials continue for milder cases.

Repeat COVID-19 cases could offer clues about people’s immunity to the novel coronavirus and how to vaccinate against it.

The company voluntarily paused its studies, including one in Phase 3, after an unexplained illness in a patient.

Harvey Alter, Michael Houghton, and Charles Rice share the Physiology or Medicine award for their contributions to identifying the virus and demonstrating that it was responsible for hepatitis among blood transfusion recipients.

Conversations between the immune and central nervous systems are proving to be essential for the healthy social behavior, learning, and memory.

Some viruses, possibly even SARS-CoV-2, can sneak into the brain through the nose. Recent studies show that microglia are ready for them when they do.

Several routes exist for immune cells to communicate with neurons in the central nervous system, though T cells rarely come in direct contact with neural tissue.

The rare complication known as multisystem inflammatory syndrome in children (MIS-C) differs from both Kawasaki disease and severe adult cases of COVID-19, a study finds.

Fewer than 1 in 10 dialysis patients sampled had antibodies against the novel coronavirus as of July, indicating that the greater population is far from levels required to achieve herd immunity.

Adeno-associated viral vectors can deliver gene therapies, but AAV-neutralizing antibodies might prevent the medicines from working.
