New measurement technique shows link between T-cells, aging

Researchers discover a new correlation between aging and the effectiveness of T-Cells. The research is based on a novel technique, called iTAST (in situ TCR affinity and sequence test), that is able to measure a T-cell's so-called affinity, a physical parameter that determines how well T-cell receptors recognize and bind to their antigens, such as those derived from bacteria, viruses or cancer cells.
