Abstract

Severe burn results in immunosuppression, with increased lymphocyte apoptosis in both the central and peripheral immune system. As atrophy of the small intestine has been described in mouse models and intestinal lymphocytes have been implicated in the burn inflammatory response, we examined the effects of burn and tumor necrosis factor (TNF)-alpha on lymphocytes in intestinal Peyer's patches. Anesthetized C57BL6 mice received a 30% full-thickness scald burn on the upper back. Sham-burned animals served as controls. Anti-TNF or control immunoglobulin (Ig) G antibody (200 microg) was given immediately after the burn. The animals were initially resuscitated with 2 mL of normal saline, and were then sacrificed 12 h postburn. Terminal deoxyuridine nick-end labeling (TUNEL) and proliferative cell nuclear antigen (PCNA) staining was performed. Apoptosis was quantified as apoptotic lymphocytes/high-powered field (hpf). Results, expressed as mean +/- SEM, were compared using analysis of variance (ANOVA) and the Student-Newman-Keuls test. All mice survived the burn. An initial time-course experiment demonstrated maximal Peyer's patch apoptosis 12 h after the burn. Sham mice had 25 +/- 7 TUNEL-stained cells/hpf in Peyer's patches, whereas burned mice had 93 +/- 18 cells/hpf (P < 0.05). In contrast, burned mice receiving anti-TNF antibody had 28 +/- 8 TUNEL-stained cells/hpf (P < 0.05 vs. burn), whereas sham mice receiving anti-TNF antibody had 20 +/- 4 cells/hpf. There were no significant differences in PCNA staining between the groups. Scald burn results in lymphocyte apoptosis in Peyer's patches. This apoptosis can be abrogated by the addition of anti-TNF antibody. Apoptotic changes may lead to the failure of the intestinal immunological barrier and increased risk of sepsis.
