Of the 24 measured cytokines, serum levels of APRIL (p = 0.002); IL-19 (p = 0.013); IL-20 (p = 0.031); IL-28A (p = 0.008) and IL-35 (p = 0.042) were significantly higher in all patients with MG compared to healthy controls (HC) (Fig. 1 and Table 1). This evidence concerns the gene TNFSF13 and myasthenia gravis.
