Gene expression in LCMV-specific Blimp-1 deficient effector CD8+ T cells compared to wildtype effector CD8+ T cells

ABSTRACT: Antigen-specific effector CD8+ T cells deficient in Blimp-1 (Prdm1) do not acquire maximal effector functions, evade terminal differentiation, and more rapidly acquire some hallmark properties of memory CD8+ T cells. In this study, we compared the gene expression profiles of wildtype and Prdm1-/- LCMV-specific effector CD8+ T cells to better understand the molecular mechanisms underlying this striking phenotype. DNA microarray analysis was performed of DbGP33-41 and DbNP396-404 tetramer-positive effector CD8+ T cells FACS-sorted at day 8 post-LCMV infection from four independent samples of either Blimp-1 conditional knockout mice (CKO; Blimp-1flox/flox x GranzymeB-cre+) or wildtype (WT) littermate controls.

During acute infections, a small population of effector CD8(+) T cells evades terminal differentiation and survives as long-lived memory T cells. We demonstrate that the transcriptional repressor Blimp-1 enhanced the formation of terminally differentiated CD8(+) T cells during lymphocytic choriomeningitis virus (LCMV) infection, and Blimp-1 deficiency promoted the acquisition of memory cell properties by effector cells. Blimp-1 expression was preferentially increased in terminally differentiated  ...[more]
