Introduction: Neutrophils (PMNs) firmly adhere to endothelium via ICAM-1. IV-TPN increases intestinal ICAM-1 and PMN accumulation, and decreases intestinal IL-4 and IL-10, cytokines which down-regulate ICAM-1 expression. P- and E-selectin mediate PMN recruitment via rolling prior to firm adhesion. This work examines P- and E-Selectin expression in uninjured mice manipulated by nutrition. Methods: 53 mice were randomized to chow, IV-TPN or intragastric (IG)-TPN. After 5 days of diet, mice were administered 125-I labeled anti-P-selectin Ab (or 125-I anti-E-selectin Ab) and 131-I labeled non-binding Ab to quantify P-selectin (or E-selectin) expression in various organs. Results: E-selectin expression was undectable in intestine, but increased significantly in lung after 5 days of IV-TPN. IV-TPN increased P-selectin only in intestine. Conclusion: In a time frame (5 days) when ICAM-1 and neutrophil recruitment is increased, gut expression of P-selectin remains up regulated. Possible early lung inflammatory changes, reflected by increases in E-selectin, may indicate early pulmonary dysfunction with IV-TPN, and requires further study.
