Triggering Receptor Expressed on Myeloid cells-1 (TREM-1) is expressed by human subcutaneous and omental pre-adipocyte and adipocytes. (A) Confocal fluorescent images of human subcutaneous (top panels) and omental (bottom panels) pre-adipocytes and adipocytes. Cells were stained with anti-human TREM-1 (red), DAP-12 (green), and TO-PRO3 (blue) mAbs, Scale bars: 100 µm. (B) Western blot of lysates of human subcutaneous and omental pre-adipocytes and adipocytes treated for 2, 4, 6, and 24 hours with LPS (100 ng/ml). Images are representatives from 3 different experiments each performed on three different donors.

Applications for Human TREM‑1 Antibody

Application
Recommended Usage

Agonist Activity

Measured by its ability to stimulate TNF-alpha secretion by human peripheral blood mononuclear cells [Bouchon, A. et al. (2001) Nature 410:1103 and Bouchon, A. et al. (2000) J. Immunology 164:4991].
The ED50 for this effect is typically 1-4 μg/mL.

CyTOF-ready

Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.

Background: TREM-1

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. The natural ligand for TREM-1 has not been identified. However, engagement of TREM-1 with an agonist 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. Human and mouse TREM-1 share approximately 42% amino acid sequence homology (1-3).
