Pattern recognition receptors

Pattern recognition receptors (PRRs) are expressed by cells in the body in order to sense molecules that are associated with infection or tissue damage. They are important for activating the immune system.

    Guanylate-binding proteins (GBPs) promote immune defenses against infectious agents. Two studies reveal that GBP1 directly binds to cytosolic lipopolysaccharide (LPS), bringing caspase-4 to the surface of bacteria to induce pyroptosis.

    Caspase-cleaved gasdermin D forms pores in cellular membranes, thus executing proinflammatory cell death by pyroptosis. Disulfiram — a drug used to treat chronic alcoholism — is now found to be an inhibitor of pore formation, which may therapeutically counteract exacerbated inflammation in sepsis and beyond.
