The mammalian vomeronasal organ detects social information aboutgender, status, and individuality. The molecular cues carryingthis information remain largely unknown. Here, we show thatsmall peptides that serve as ligands for major histocompatibilitycomplex (MHC) class I molecules function also as sensory stimulifor a subset of vomeronasal sensory neurons located in the basalGao- and V2R receptorexpressing zone of the vomeronasalepithelium. In behaving mice, the same peptides function asindividuality signals underlying mate recognition in the contextof pregnancy block. MHC peptides constitute a previously unknownfamily of chemosensory stimuli by which MHC genotypic diversitycan influence social behavior.
