These cytokines were selected for analyses based on their well‐known significance in modulating inflammation response and immune system regulation.[20] The expression of pro‐inflammatory cytokines IL1β, IL2, IL6, and TNFα was significantly increased in RP mice, whereas that of anti‐inflammatory cytokines IL4 and IL5 was significantly decreased (Figure 3F). Here, IL4 is linked to retinitis pigmentosa 1.
