Tropomyosin: An Excretory/Secretory Protein from <i>Haemonchus contortus</i> Mediates the Immuno-Suppressive Potential of Goat Peripheral Blood Mononuclear Cells In Vitro
During host-parasite interactions, binding of excretory/secretory proteins (ESPs) on the host immune cells is considered the fundamental phase for regulation of immune responses. In this study, gene encoding <i>Haemonchus contortus </i>tropomyosin (Hc-TpMy), was successfully cloned and e...
