Memory T cells are a special type of white blood cell that "remember" past infections and vaccines, helping our bodies to quickly respond if we encounter the same germs again. These cells are found ...

T cells are central to adaptive immunity, orchestrating targeted responses against infections and malignancies while forming a durable immunological memory. Memory T cells, particularly CD8+ subsets, ...

During vaccination, the immune system is purposefully exposed to weakened, inactivated, or a component of pathogens so that the body can recognize their molecular structures in the future and mount a ...

Even when immune memory cells form in the lung after influenza infection, insufficient dietary iron leaves them less able to mount a strong antiviral response, revealing how nutrition can shape ...

A multi-institutional study has mapped the genetic circuitry that determines whether CD8 killer T cells become durable immune defenders or lapse into exhaustion, and has shown that disabling two ...

Scientists uncover a new “recipe” that shows how exhausted T cells can be reprogrammed to regain their ability to attack tumors.

CD8 + cytotoxic T lymphocytes (CTLs) serve as central effectors in cancer immunotherapy by directly eliminating tumor cells. However, current clinical therapies face significant limitations. These ...
