Animals and plants respond to the presence of pathogenic microbes in their environment by triggering host defence mechanisms. Many of these innate defence strategies are ancient and highly conserved with plants, invertebrates and vertebrates sharing surprisingly similar responses including upregulation of antimicrobial peptides and activation of phagocytosis. As a consequence of this, invertebrate model systems, including Caenorhabditis <\/i>elegans<\/i>, have provided important insights into the molecular mechanisms that underlie infection responses. We have shown that C. <\/i>elegans<\/i> uses G\u03b1q signaling pathways to regulate behavioural and cellular responses to infection. Here I will describe our recent work to identify the G-protein coupled receptors acting upstream of G\u03b1q. I will present data identifying a novel C. <\/i>elegans<\/i> GPCR that is activated by its endogenous ligand during infection in order to regulate host infection responses.<\/p>\n
