Journal ArticleDOI

The immunomodulatory adapter proteins DAP12 and Fc receptor γ-chain (FcRγ) regulate development of functional osteoclasts through the Syk tyrosine kinase

TL;DR: Data indicate that recruitment of Syk to phosphorylated ITAMs is critical for osteoclastogenesis, which provides new insight into the biology of osteoclasts and suggest novel therapeutic targets in diseases of bony remodeling.
Journal ArticleDOI

Cutting Edge: Inhibition of TLR and FcR Responses in Macrophages by Triggering Receptor Expressed on Myeloid Cells (TREM)-2 and DAP12

TL;DR: It is shown that Triggering Receptor Expressed on Myeloid cells (TREM)-2 is responsible for the DAP12-mediated inhibition in mouse macrophages and the interaction of TREM-2 and its ligand results in an inhibitory signal that can reduce the inflammatory response.
Journal ArticleDOI

TREM2- and DAP12-dependent activation of PI3K requires DAP10 and is inhibited by SHIP1.

TL;DR: A previously uncharacterized interaction of SHIP1 with DAP12 is demonstrated that functionally limits TREM2- and DAP 12-dependent signaling and a mechanism through which SHIP 1 regulates key ITAM-containing receptors by directly blocking the binding and activation of PI3K is identified.
