GPR183 and systemic lupus erythematosus: We next investigated EBI2 expression in TMPD‐induced SLE mice, since this model exhibits many clinical features of lupus patients.[23] The transcription of Ebi2 was decreased in peripheral blood cells (Figure 3A), splenocytes (Figure 3B), and most significantly in peritoneal cells (Figure 3C) of TMPD‐induced SLE mice, but showed minor or no changes in liver, kidney, lung, and heart (Figure S2F–I, Supporting Information).
