Th17 signaling molecules increased specially in WSX-1−/−-experimental allergic conjunctivitis (EAC) mice compared with C57BL/6-EAC, BALB/c-EAC, and PBS controls. Production of IL-17A and IL-17F at mRNA and protein levels by conjunctiva (A-B) and by CLNs (C-E); F-G, RORγt expression and immunopositive cells in CLNs. Results shown are Mean ± SD. *P < 0.05, **P < 0.01, n = 5, compared with controls
