huTREM1-CHO-S is used in immunological research to study inflammatory responses, particularly in the context of innate immunity. It serves as a soluble form of the human Triggering Receptor Expressed on Myeloid cells-1 (TREM1), acting as a decoy receptor to modulate excessive inflammation. By binding to TREM1 ligands, it helps suppress pro-inflammatory signaling pathways, making it a valuable tool in investigating therapies for sepsis, acute respiratory distress syndrome (ARDS), and other inflammatory conditions. Its application extends to in vitro and in vivo models where control of cytokine storms and immune overactivation is critical. Additionally, it supports the development of biologics aimed at treating chronic inflammatory and autoimmune diseases.
