"The triggering receptor expressed on myeloid cells 1 (TREM-1) plays an important role in the innate immune response related to severe infections and sepsis. Although the identity and occurrence of the natural TREM-1 ligands are so far unknown, the presence of a ligand for TREM-1 on human platelets has been established. It has been suggested that TREM1 recognizes soluble proteins or cell-surface proteins which are upregulated as a result of inflammation and/or tissue damage and also bacterial LPS (Tessarz & Cerwenka 2008)."^^ . . . . . . .
