A, B The fluorescence intensity of the Cx43 or GFAP in the Sham group was lower than that in the IE group. C The Cx43 mRNA expression in the Sham group was lower than that in the IE group. D The Etd uptake ratio was lower in the TAT-Gap19-IE, siRNA Cx43-IE, sTNF-αR1-IE, IL-1ra-IE or MR16-1-IE group when compared with that in the IE group. *p < 0.05, **p < 0.01, ***p < 0.001,****p < 0.0001.
