Mast cells and basophils are central to acquired resistance against blood-feeding arthropods which, in turn, counteract these cells by modulating their biological activities. The phenotypic exuberance displayed in this battlefield points to a reciprocal selective pressure suggesting a coevolutionary arms race that shapes both ectoparasites and vertebrate hosts.
Keywords: basophils; blood-feeding arthropods; coevolution; mast cells; phenotypic exuberance.
