[https://www.uniprot.org/uniprot/TREM1_HUMAN TREM1_HUMAN] Stimulates neutrophil and monocyte-mediated inflammatory responses. Triggers release of pro-inflammatory chemokines and cytokines, as well as increased surface expression of cell activation markers. Amplifier of inflammatory responses that are triggered by bacterial and fungal infections and is a crucial mediator of septic shock.<ref>PMID:10799849</ref> <ref>PMID:11323674</ref>

== Publication Abstract from PubMed ==
 +
The triggering receptor expressed on myeloid cells (TREM) family of single extracellular immunoglobulin receptors includes both activating and inhibitory isoforms whose ligands are unknown. TREM-1 activation amplifies the Toll-like receptor initiated responses to invading pathogens allowing the secretion of pro-inflammatory chemokines and cytokines. Hence, TREM-1 amplifies the inflammation induced by both bacteria and fungi, and thus represents a potential therapeutic target. We report the crystal structure of the human TREM-1 extracellular domain at 1.47 A resolution. The overall fold places it within the V-type immunoglobulin domain family and reveals close homology with Ig domains from antibodies, T-cell receptors and other activating receptors, such as NKp44. With the additional use of analytical ultracentrifugation and 1H NMR spectroscopy of both human and mouse TREM-1, we have conclusively demonstrated the monomeric state of this extracellular ectodomain in solution and, presumably, of the TREM family in general.
