TREM-1 (Triggering Receptor Expressed on Myeloid cells) is a type I transmembrane protein having a single Ig-like domain. It associates with the adapter protein, DAP12, to deliver an activating signal. Several other TREM family members have been reported that are structurally similar but share less than 30% amino acid identity. TREM-1 is expressed on blood neutrophils and a subset of monocytes, and expression is up-regulated by bacterial LPS. Engagement of TREM-1 with a monoclonal antibody leads to expression of IL-8, MCP-1, and TNF-alpha suggesting that this receptor plays an important role in inflammatory responses. TREM-1 is expressed at high levels on neutrophils of patients with microbial sepsis and in mice with LPS-induced shock. Blockade of TREM-1 with a TREM-1/Fc fusion protein protected mice against LPS-induced shock.
TREM1: An inflammatory signal protein with a potential role in cancer TREM1 is pro-inflammatory gene that stimulates neutrophil and monocyte-mediated inflammatory responses. This protein is highly expressed in adult liver, lung and spleen. It is also present in the lymph node, spinal cord and heart tissues. TREM-1 plays... Read full blog post. |
