Advanced imaging technologies are uncovering surprising roles for CD8+ T cells—not just in immune defense, but also in supporting tissue repair and regeneration.

This is a useful study in the role of CHI3L1 in Kupffer cells, the macrophages of the liver, showing that CHI3L1 alters glucose regulation in obesity. Specifically, Chi3l1 protects glucose-dependent ...

NK-cell cytotoxicity can also eliminate other uninfected, activated monocytes and DCs to provide additional and crucial immunoregulatory function. In normal individuals, ...

Lymphocyte activation occurs when lymphocytes (B cells or T cells) are triggered through antigen-specific receptors on their cell surface. This causes the cells to proliferate and differentiate ...
