CTL differentiation: WT vs. IL-2Ra deficient CTL

ABSTRACT: Gene expression analysis of WT and IL-2Ra-deficient CTL (P14) isolated 8 days after inffection with LCMV. The goals of the study are to assess the impact of IL-2 signals on effector and memory CTL differentiation. Overall design: This is a 2-condition experiement comparing WT P14 Tg T cells eight days after LCMV infection to IL-2Ra-deficient P14 Tg T cells isolated at the same time from the same host. Cells are isolated via FACS-sorting form the spleen.

IL-2 provides a memory differentiation signal to CD8+ T cells during the primary response that impacts the ability of the subsequent memory pool to mount a successful recall response. In this study, we find that although primary effector CTL development is modestly decreased in the absence of IL-2, the persistence of short-term and long-term effector memory CD8+ T cells on pathogen clearance is greatly diminished. Furthermore, secondary challenge of CD8+ memory T cells lacking the high-avidity I  ...[more]
