Regulation of CD8 T cell differentiation by the RNA-binding protein DDX5


ABSTRACT: The RNA-binding protein DDX5 is a polyfunctional regulator of gene expression, but its role in CD8+ T cell biology has not been extensively investigated. In this study, we demonstrate that deletion of DDX5 reduced differentiation of terminal effector (TE), effector memory (TEM), and terminal effector memory (t-TEM) cells while increasing the generation of central memory (TCM) cells; forced expression of DDX5 elicited the opposite phenotype. DDX5-deficient CD8+ T cells exhibited increased expression of genes that promote TCM cell differentiation, including Tcf7 and Eomes. Together, these findings reveal a role for DDX5 in regulating the differentiation of effector and memory CD8+ T cell subsets in response to microbial infection.
