Murine lupus susceptibility locus Sle1a controls regulatory T cell number and function through multiple mechanisms.

Abstract excerpt

The Sle1 locus is a key determinant of lupus susceptibility in the NZM2410 mouse model. Within Sle1, we have previously shown that Sle1a expression enhances activation levels and effector functions of CD4(+) T cells and reduces the size of the CD4(+)CD25(+)Foxp3(+) regulatory T cell subset, leading to the production of autoreactive T cells that provide help to chromatin-specific B cells. In this study, we show...
