Study of the roles of caspase-3 and nuclear factor kappa B in myenteric neurons in a P2X7 receptor knockout mouse model of ulcerative colitis

Figure 7 Number of calretinin-ir and P2X7 receptor-ir neurons per myenteric ganglion in the distal colon in mice from the wild-type sham 24 h and 4 d, wild-type colitis 24 h and 4 d, knockout sham 24 h and 4 d, and knockout colitis 24 h and 4 d groups. A: Calretinin-ir; B: P2X7 receptor-ir. The data are presented as the arithmetic mean ± SE. ^aP < 0.05 vs sham groups; ^cP < 0.001 vs sham groups; NS: Not significant. WT: Wild-type; KO: Knockout.
