Comparison of IL-37 mRNAs and protein levels between OA and HC. Expression of IL-37 mRNAs in PBMCs from primary generalized OA (n = 40), erosive inflammatory OA (n = 32) OA patients and HCs (n = 40) was detected by RT-PCR (a). Serum IL-37 protein levels were determined by ELISA (b). Each symbol represents an individual OA patient and HC. The results are presented as mean ± SD.
