When killer T cells of our immune system divide, they normally undergo asymmetric cell division (ACD): Each daughter cell ...

As people age, their immune system function declines. T cell populations become smaller and can't react to pathogens as ...

New data highlight liver-encoded delivery of immune modulators as a strategy to mitigate age-related immune dysfunction.

Researchers at MIT and the Broad Institute have found a way to overcome age-related immune system decline by temporarily programming cells in the liver to take over a critical immune system function: ...

Testing in mice suggests that rejuvenating T cells could make vaccines and some cancer therapies more effective.

Work on peacemakers in the immune system won the 2025 Nobel Prize in physiology or medicine. The peacemakers are regulatory T cells, a type of immune cell that calms the immune system after it has ...

A hidden “jack-in-the-box” mechanism inside T cells may hold the key to unlocking more powerful cancer immunotherapies.

In most solid tumors, high numbers of regulatory T (Treg) cells are associated with poorer outcomes because they dampen the ...

This article explores how the role of regulatory T cells in immunological self-tolerance evolved from skepticism to Nobel ...
