Mechanisms of immunity operating in honey bee blood An important aspect of immunity concerns how responses to infections are mediated. That is, what is the cellular basis for the sequence of biochemical events occurring between initial infection and an immune response. It is well known that an immune response requires the existence of cells which can encounter, recognize and then respond to foreign molecules penetrating the insect haemocoel. The response of these cells must result in the initiation of cellular defence reactions or in the production of antibacterial proteins in the haemolymph.
