Immune-related traits

A number of attempts have been made to select on nematode immune-related traits. Lines of Heligmosomoides polygyrus have been selected in hosts with different histories of previous exposure (naive, once previously exposed, or multiply previously exposed). This resulted in parasite lines that differed in fitness when tested in semi-immune animals, with the lines selected in the hosts with greatest previous exposure surviving best and... [Pg.102]

IGF (insulin-like growth factors) group of closely related hormones, with important effects on sexual maturation, among many other effects, immunosuppression lowering of responsiveness of the immune system to antigens, individual selection evolutionary selection of traits that benefit individuals rather than populations. It is by far the most important form of natural selection. [Pg.362]
