IL6 and systemic lupus erythematosus: Recent results showed that let-7a was significantly increased in mesangial cells of NZBWF1/J mice (common name NZB/W, this mouse model develops an autoimmune disease resembling human SLE) compared to age-matched NZW/LacJ mice (common name NZW, F1 hybrids of NZW/LacJ and NZB/BlNJ are used as a model for human SLE) and might be involved in regulating IL6 production in these cells [65].
