Based on the notion that eliminating the diseases caused by parasites depends on research into the molecular basis of host-parasite interaction from a wide range of biological disciplines, 25 articles discuss recent advances in determining the structure of antigenic epitopes, the molecular mechanisms of immune recognition, the action of cytokines and hormones, and the genetics of parasites.
