How pattern recognition receptors NOD1 and NOD2 sense bacterial muropeptides from extracellular bacteria to drive keratinocyte inflammation remains unclear. In this issue of Immunity, Bharadwaj et al. show that the solute carrier 46A2 (SLC46A2) delivers DAP-muropeptides into the cytosol to drive NOD1 activation in keratinocytes and elicit skin inflammation during psoriasis.
