Technical Advance: Fluorescent reporter reveals insights into eomesodermin biology in cytotoxic lymphocytes.

abstract：:Immune exhaustion in T cells significantly impacts their ability to control malignancies and infections, and its discovery has led to revolutionary therapies for cancer in the form of checkpoint blockade. NK cells, like T cells, are lymphocytes that recognize virally infected and malignantly transformed cells. However...
