Neutropenia has been shown to markedly increase plasma TNF-alpha concentration after LPS injection and to enhance LPS-induced mortality. Experiments reported here demonstrate that the 15-fold higher plasma TNF-alpha concentration elicited by LPS in neutropenic vs. nonneutropenic unanesthetized mice correlated with increased hepatic and splenic, but not pulmonary, TNF-alpha mRNA. Core 2 beta-1,6-N-acetylglucosaminyltransferase-null and CD18-deficient mice also exhibited exaggerated plasma TNF-alpha responses to LPS injection. Findings suggest that extravasated neutrophils inhibit systemic TNF-alpha production and that they do so through organ-selective mechanisms involving CD18 integrin and selectin binding.
