Analysis of gradient purified immune suppressive particles from L. heterotoma NY parasitoid wasp


ABSTRACT: The composition and biotic nature of wasp VLPs has remained uncharacterized. VLP proteomics have contributed to a new understanding of their unusual organelle nature and mechanism of action in suppressing host defense responses.

The evolutionary success of parasitoid wasps, a highly diverse group of insects widely used in biocontrol, depends on a variety of life history strategies in conflict with those of their hosts [1]. Drosophila melanogaster is a natural host of parasitic wasps of the genus Leptopilina. Attack by L. boulardi (Lb), a specialist wasp to flies of the melanogaster group, activates NF-κB-mediated humoral and cellular immunity. Inflammatory blood cells mobilize and encapsulate Lb eggs and embryos [2-5].  ...[more]
