Abstract
- CD300, triggering receptor expressed on myeloid cells (TREM), and TREM-like (TREML) receptors are important regulators of the mammalian immune response. Homologs of these receptors, which occur in activating and inhibitory transmembrane forms as well as soluble variants, are found throughout the jawed vertebrates. Specific ligands for most members of these receptor families remain elusive. We report here that at least 11 separate receptors from the CD300, TREM, and TREML families engage in robust and specific interactions with major polar lipids found in prokaryotic and eukaryotic cell membranes. Both soluble and membrane-bound receptor forms exhibit lipid interactions in the solid phase as well as in a physiological signaling context. Overlapping but distinctive patterns of receptor specificity suggest that the CD300/TREM system as a whole may discriminate immunological stimuli based on lipid signatures, thereby influencing downstream responses.
