Endogenous retroviruses promote aberrant T cell differentiation in systemic lupus erythematosus via the RIG-I pathway [naïve]

The dysregulated differentiation of T lymphocytes play an important role in systemic lupus erythematosus (SLE). However, the underlying mechanism remains unclear. Our findings reveal many overexpressed HERVs in CD4+ T cells from SLE patients. To investigate the role of dsRNA/RIG-I pathway in CD4+ T cell differentiation, RNA-seq was performed in CD3 and CD28 antibodies activated naive CD4+ T cells transfected with poly(I:C). The expression profiles of genes related to the effector T cell differentiation reveal that dsRNAs induced the activation of the RIG-I signaling pathway plays important roles in aberrant differentiation of T cells. Overall design: mRNA prifules of naive CD4+T cells of HCs with poly(I:C) treatment
