The results showed that, with the increase of MG infection concentration, the expressions of CXCL13L2, IL1B, TLR7, IL8L2, IL8L1, and IL4I1 were in dynamic changes; AVD and S100A9 were increased in an MG concentration-dependent manner; MMP7 was significantly up-regulated in low MG treatment, and down-regulated with the increase of MG treatment concentration (Figure 10f). The gene discussed is S100A9; the disease is myasthenia gravis.
