A receptor called LAIR-1 stops bone breakdown and immune reactions when it binds to collagen, helping maintain balance in the body.
Scientific Claim
LAIR-1 acts as an inhibitory receptor that downregulates osteoclastogenesis and immune responses when bound to collagen.
Original Statement
“LAIR-1 is an inhibitory receptor actuated by triple-helical collagen as a ligand through interaction with the collagen-related peptide, triplet (glycine-proline-hydroxyproline GPO)10. LAIR-1 is also expressed in osteoclast precursors to downregulate osteoclastogenesis. The phosphorylation of LAIR-1 containing two ITIMs recruits phosphatases SHP-1 and 2 and directly dephosphorylates Zap70, PLCγ and Syk, inhibiting ITAM-mediated stimulation of protein kinases and calcium signaling.”

This study talks about how collagen interacts with cells in general, but it never mentions LAIR-1 or how it affects bone cells or the immune system, so we can't say if the claim is true or false based on this paper.
