Abstract
Characterization of the innate immune repertoire of evolutionary old organisms is of both fundamental and applied interest; it not only provides insights into the basic immunological "tool kit" of the common ancestor of all animals but is also likely to be important in understanding human barrier disorders by describing ancient mechanisms of host/microbial interactions and the resulting evolutionary selection processes. Here, I evaluate our current understanding of the evolution of epithelial-based innate immunity. I highlight growing evidence that the innate immune system with its host-specific antimicrobial peptides and rich repertoire of pattern recognition receptors has evolved in response to the need for controlling resident beneficial microbes rather than to defend against invasive pathogens.
