ABSTRACT During the chronic phase of the infection, Trichinella spiralis, through its excretory-secretory products (ES L1), induce Th2 and regulatory immune responses, thus creating nonpermissive environment for the development of autoimmune and other chronic inflammatory diseases. Our major goal is to discover immunomodulatory components within ES L1 products, so that we can characterize them and use them to design treatment for humans. Extracellular vesicles, isolated from T. spiralis ES L1 products (TsEVs), may be the important players in initiation, progression and regulation of the immune response, via their impact on dendritic cells. Human monocyte derived dendritic cells (DCs) were treated with TsEVs and subsequently co-cultivated with allogenic T cells.
