How bacterial invaders are sensed in the gut
A new paper in the latest issue of Science describes how the bacterial-sensing proteins, NOD1/2, are recruited to the membranes of our gut cells for them to function to initiate a proper immune response. This involves the addition of a lipid, palmitoyl, to NOD1/2 by the palmitoyl-transferase ZDHHC5. Importantly variants of NOD2 that are associated with Crohn’s disease are unable to be palmitoylated. This work involved an international collaboration […]
