title: Proteomic analysis of Fasciola hepatica excretory and secretory products (FhESPs) involved in interacting with host PBMCs and cytokines by shotgun LC-MS/MS.
abstract: Fasciola hepatica is a helminth parasite with a worldwide distribution, which can cause chronic liver disease, fasciolosis, leading to economic losses in the livestock and public health in many countries. Control is mostly reliant on the use of drugs, and as a result, drug resistance has now emerged. The identification of F. hepatica genes involved in interaction between the parasite and host immune system is utmost important to elucidate the evasion mechanisms of the parasite and develop more effective strategies against fasciolosis. In this study, we aimed to identify molecules in F. hepatica excretory and secretory products (FhESPs) interacting with the host peripheral blood mononuclear cells (PBMCs), Th1-like cytokines (IL2 and IFN-γ), and Th17-like cytokines (IL17) by Co-IP combined with tandem mass spectrometry. The results showed that 14, 16, and 9 proteins in FhESPs could bind with IL2, IL17, and IFN-γ, respectively, which indicated that adult F. hepatica may evade the host immune responses through directly interplaying with cytokines. In addition, nine proteins in FhESPs could adhere to PBMCs. Our findings provided potential targets as immuno-regulators, and will be helpful to elucidate the molecular basis of host-parasite interactions and search for new potential proteins as vaccine and drug target candidates.
