Roles of 1,25(OH)2D3 and Vitamin D Receptor in the Pathogenesis of Rheumatoid Arthritis and Systemic Lupus Erythematosus by Regulating the Activation of CD4+ T Cells and the PKCδ/ERK Signaling Pathway

Abstract

Our study provide evidence that 1,25(OH)2D3 and VDR could inhibit the activation of CD4+ T cells and suppress the immune response of SLE and RA through inhibiting PKCδ/ERK pathway and promoting DNA methylation of CD11a, CD70 and CD40L.
