Disruption of Tumor Necrosis Factor Receptor-Associated Factor 5 Exacerbates Murine Experimental Colitis via Regulating T Helper Cell-Mediated Inflammation

Table 2

Histological scoring system used in this study.

Point	Epithelial damage	Inflammatory cell infiltration
0	Normal morphology	No infiltrate
1	Loss of goblet cells	Infiltrate around crypt base
2	Loss of goblet cells in large areas	Infiltrate reaching the L. muscularis mucosae
3	Loss of crypts	Extensive infiltration reaching the L. muscularis mucosae and thickening of the mucosa with abundant edema
4	Loss of crypts in large areas	Infiltration of the L. submucosa
