Host innate responses to bacterial infections are primarily mediated by neutrophils and monocytes/macrophages. These cells express pattern recognition receptors (PRRs) that bind conserved molecular structures shared by groups of microorganisms. Stimulation of PRR signalling pathways initiates secretion of proinflammatory mediators, which promote the(More)
Gene targeting of the adaptor molecule DAP12 in mice caused abnormal distribution and impaired antigen presentation capacity of dendritic cells (DCs). However, the DAP12-associated receptors expressed on DCs and their functions have not been identified yet. Here we show that the triggering receptor expressed on myeloid cells-2 (TREM-2) is a cell surface(More)
Sepsis still represents an important clinical and economic challenge for intensive care units. Severe complications like multi-organ failure with high mortality and the lack of specific diagnostic tools continue to hamper the development of improved therapies for sepsis. Fundamental questions regarding the cellular pathogenesis of experimental and clinical(More)
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a member of the tumor necrosis factor family and has recently been shown to exert tumoricidal activity in vivo in the absence of any observable toxicity. The signaling pathways triggered by TRAIL stimulation and the mechanisms involved in resistance against TRAIL-mediated apoptosis are still(More)
