Gene expression and secretion of inflammatory factors in LPS-treated BV2-N and LPS-treated BV2-MC at different concentration (0 ng/ml, 50 ng/ml, 500 ng/ml and 5 μg/ml). Increased gene expression (a) and protein secretion (b) of inflammatory factors in BV2-N was observed as the concentration of LPS increased, but no difference was observed in BV2-MC (BV2-N: normal BV2 cell, BV2-MC: mycoplasma-contaminated BV2 cell)
