Interaction between neutrophils and Schistosoma mansoni larvae in vivo: a transmission electron-microscopic study Interação entre neutrófilos e larvas de Schistosoma mansoni in vivo: estudo ao microscópio eletrônico de transmissão

Schistosoma mansoni cercariae were inoculated into the peritoneal cavity of naive mice and recovered 30 minutes later. Ultrastructural studies showed that neutrophils adhere to the larval surface and participate in the removal of glycocalyx by phagocytosis. This finding suggests that the neutrophils...

Description
Summary:Schistosoma mansoni cercariae were inoculated into the peritoneal cavity of naive mice and recovered 30 minutes later. Ultrastructural studies showed that neutrophils adhere to the larval surface and participate in the removal of glycocalyx by phagocytosis. This finding suggests that the neutrophils can play a role on the cercaria-schistosomulum transformation process. Cercárias de Schistosoma mansoni foram inoculadas na cavidade peritoneal de camundongos normais e recuperadas 30 minutos depois. Estudos ultra-estruturais mostraram que neutrófilos aderem à superfície da larva, participando da remoção do glicocálice através de fagocitose. Este achado sugere que neutrófilos possam ter papel no processo de transformação de cercária em esquistossômulo.
