Résumé
Although eosinophils and other inflammatory cells from the circulation and peritoneal cavity can damage Trichinella spiralis newborn larvae (NBL) in vitro, the cytotoxic potential of cells from the intestinal lamina propria, a site that may be the first line of defense against NBL migration, is unknown. Accordingly, we examined the interaction between NBL and isolated intestinal lamina propria cells (ILPC), including an enriched eosinophil population, from rats and humans. Rat ILPC killed NBL in vitro only after a prolonged incubation of 6 days. However they strongly adhered to NBL after only 4 hr incubation and prevented muscle establishment of NBL injected intravenously. Human ILPC showed similar adherence as rat ILPC but no killing was seen at the incubation time tested (36 hr).
