Effect of SRSF1 splicing factor knockdown in the physiology and function of cytotoxic CD8 T lymphocytes and a potential molecular mechanism in viral immunopathogenesis

Cytotoxic CD8 T cells are crucial for the host antigen-specific immune response to viral pathogens. Here we report the identification of an essential role for the serine/arginine-rich splicing factor (SRSF) 1 in CD8 T cell homeostasis and function Transcriptomics analyses of Srsf1-deficient T cells reveal that SRSF1 controls cell cycle, MAP kinase signaling and IFN signaling pathways. Overall design: Comparative gene expression profiling analysis of RNA-seq data for Srsf1.flox dLck.cre spleen total T cells of B6 mice after LCMV infection for 8 days.
