Triggering receptor expressed on myeloid cells 1 (ACUTE INFLAMMATION)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 triggered by bacterial and fungal infections and is a crucial mediator of septic shock. Strongly expressed in acute inflammatory lesions caused by bacteria and fungi. Here, TREM1 is linked to fungal infectious disease.
