HMGB1 promoted the activation of canonical NLRP3 inflammasome in retinal IR injury. The intravitreal injection of exogenous rHMGB1 significantly promoted the mRNA and protein production of NLRP3 (a, c) and ASC (e, g) and activation of caspase-1 (i). Thus, the intravitreal injection of HMGB1 inhibitor, GA, significantly suppressed the production of NLRP3 (b, d) and ASC (f, h) and activation of caspase-1 (j). Data are shown as mean ± SD. *P < 0.05, **P < 0.01 vs sham group
