title: Innate immunity in C. elegans.
abstract: The nematode Caenorhabditis elegans is proving to be a powerful invertebrate model to study host-pathogen interactions. In common with other invertebrates, C. elegans relies solely on its innate immune system to defend itself against pathogens. Studies of the nematode response to infection with various fungal and bacterial pathogens have revealed that the innate immune system of C. elegans employs evolutionary conserved signalling pathways. They regulate the expression of various effectors molecules, some of which are also conserved. Here, we summarize the current knowledge of the pathways and effector molecules involved in the nematode immune response, with a particular focus on the antifungal immune response of the C. elegans epidermis.
