FIG. 5.
Infiltration of gastric mucosa with polymorphonuclear granulocytes (stained with MAb Gr1) showed no significant difference between TNF-R1-deficient mice (A and B) and wild-type mice (C and D) (magnification, ×200). Uninfected controls consisting of wild-type mice (C) and TNF-R1-deficient mice (D) showed significantly less (P < 0.0001) infiltration of the gastric mucosa with polymorphonuclear granulocytes.
