Identification and immuno-electron microscopy localization of p40, a protein component of immunosuppressive virus-like particles from Leptopilina heterotoma, a virulent parasitoid wasp of Drosophila.

Lamellocytes are specialized larval blood cells of Drosophila that carry out encapsulation of metazoan pathogens such as parasitoid wasps. Large virus-like particles (VLPs) from two closely related virulent parasitoid wasp species, Leptopilina heterotoma and Leptopilina victoriae, suppress the host encapsulation response by promoting lysis of lamellocytes… CONTINUE READING
