Various inflammatory cytokines/chemokines, such as IL-6, IL-17A, CXCL13 in cerebrospinal fluid, and IL-2 in plasma, and miRNAs (like e.g., Let-7b) in plasma, have been shown to play important roles in the process of anti-NMDAR encephalitis (5, 6, 12). The gene discussed is IL2; the disease is viral encephalitis.
