Strength of TRAF6 signalling determines osteoclastogenesis [PDF]
TRANCE/TRAF6 signalling governs osteoclastogenesis in vivo. Only the TRANCE receptor (TRANCE-R) has been shown to induce osteoclastogenesis, even though other immune receptors, including CD40 and IL-1R/Toll-like receptor, use TRAF6 to activate overlapping signalling cascades.
