WebT Cell Exhaustion. T-cell exhaustion is a broad term used to describe T cell dysfunction resulting from chronic stimulation. Exhausted T cells present with a distinct phenotype including overexpression of inhibitory markers such as PD-1, LAG-3 and TIM-3 as well as impairment in their ability to release pro-inflammatory cytokines (IFNγ and TNFα). WebReducing the in vitro expansion time for CAR-T cells is also being considered as a strategy to limit differentiation to effector T cells. 14 Such protocols rely on the ability of the activation reagent to induce rapid activation and T-cell proliferation. The in situ DNA hybridization strategy is particularly attractive offering many advantages.
