T-cell activation involves two phases, enabling a more precise immune response. This insight may boost cancer immunotherapy ...

the team found that naive T cells—cells that have never encountered an antigen—and memory T cells were more likely to take up telomeres. Meanwhile, various types of effector T cells are less likely to ...

Cytotoxic T cells are an important component of the immune system. Once activated, they differentiate into either short-lived effector cells or long-lived memory cells. Studies by researchers at ...

Researchers have uncovered a critical, previously underappreciated role for B cells in vaccine protection. Best known for producing antibodies, B cells also guide other immune cells, specifically CD8 ...

T & B cells in aging The pool of naive cells is reduced, while effector memory and potentially dysfunctional late-differentiated cell numbers are increased. Expansion of antigen-specific T cells ...

“The compartmentalization [of naive T cells] is the biggest story.” Previous studies of immune cell populations in people relied on blood samples to pick up circulating T cells, but the Columbia team ...

The lower respiratory tract is covered with a 75 m 2 monolayer of epithelial cells that separate the outside world from the underlying vasculature and protect the interstitial tissue.
