Natural Genetic Variation in the Caenorhabditis elegans Response to Pseudomonas aeruginosa.

ABSTRACT: Caenorhabditis elegans responds to pathogenic microorganisms by activating its innate immune system, which consists of physical barriers, behavioral responses, and microbial killing mechanisms. We examined whether natural variation plays a role in the response of C. elegans to Pseudomonas aeruginosa using two C. elegans strains that carry the same allele of npr-1, a gene that encodes a G-protein-coupled receptor related to mammalian neuropeptide Y receptors, but that differ in their genetic backgrounds. Strains carrying an allele for the NPR-1 215F isoform have been shown to exhibit lack of pathogen avoidance behavior and deficient immune response toward P. aeruginosa relative to the wild-type (N2) strain. We found that the wild isolate from German
