Scientists are examining the role of T cells, which are likely crucial for long-term protection against SARS-CoV-2.

A rogue hybrid lymphocyte, bearing characteristics of both B and T cells, may play a role in driving autoimmunity in the disease, although the mechanism is far from clear.

Human natural killer cells, previously considered not to participate in adaptive immunity, remember viral antigens after initial exposures, according to a new study.

The transcriptional regulator dampens the immune system’s ability to elicit an antitumor response, a study shows.

The immune system tolerates the colonization of commensal bacteria on the skin with the aid of regulatory T cells during the first few weeks of life, a mouse study shows.

When influenza invades the mouse respiratory tract, neutrophils guide the subsequent T-cell attack on infected tissue, scientists show.  

Researchers find evidence that measles vaccines reduced deaths from other infectious diseases due to “immune amnesia.”

A census of adaptive immune system components in human skin reveals a variety of resident and traveling memory T cells.

Sequencing cells from human fetal blood samples, researchers track the development of the adaptive immune system throughout gestation.
