TLDR
The two systems should be understood to be integrated and operating in the context of the 'osteoimmune' system, a heuristic concept that provides not only a framework for obtaining new insights by basic research, but also a scientific basis for the discovery of novel treatments for diseases related to both systems.Citations

Evidence for osteocyte regulation of bone homeostasis through RANKL expression
Tomoki Nakashima,Mikihito Hayashi,Takanobu Fukunaga,Kosaku Kurata,Masatsugu Oh-hora,Jian Q. Feng,Lynda F. Bonewald,Tatsuhiko Kodama,Anton Wutz,Erwin F. Wagner,Josef M. Penninger,Hiroshi Takayanagi,Hiroshi Takayanagi +12 more
TL;DR: It is found that purified osteocytes express a much higher amount of receptor activator of nuclear factor-κB ligand (RANKL) and have a greater capacity to support osteoclastogenesis in vitro than osteoblasts and bone marrow stromal cells.
Journal ArticleDOI
Functions of RANKL/RANK/OPG in bone modeling and remodeling.
Brendan F. Boyce,Lianping Xing +1 more
TL;DR: The current understanding of the role of the RANKL/RANK/OPG system in bone modeling and remodeling is reviewed to show that the relative concentration of RankL and OPG in bone is a major determinant of bone mass and strength.
Book
Skeletal Tissue Mechanics
TL;DR: This poster presents a probabilistic procedure for estimating the mechanical properties of bone based on known mechanisms, including compressive forces, compressive strength, and the compressive properties of Bone.

Biology of Bone Tissue: Structure, Function, and Factors That Influence Bone Cells
Rinaldo Florencio-Silva,Gisela Rodrigues da Silva Sasso,Estela Sasso-Cerri,Manuel Simões,Paulo Sérgio Cerri +4 more
TL;DR: Current data about the structure and functions of bone cells and the factors that influence bone remodeling are discussed, indicating the dynamic nature of bone tissue.

Pathogenic conversion of Foxp3+ T cells into TH17 cells in autoimmune arthritis.
Noriko Komatsu,Kazuo Okamoto,Shinichiro Sawa,Tomoki Nakashima,Masatsugu Oh-hora,Tatsuhiko Kodama,Sakae Tanaka,Jeffrey A. Bluestone,Hiroshi Takayanagi +8 more
TL;DR: It is shown that TH17 cells originating from Foxp3+ T cells have a key role in the pathogenesis of autoimmune arthritis.

Toll-like receptor signalling
Shizuo Akira,Kiyoshi Takeda +1 more
TL;DR: Rapid progress that has recently improved the understanding of the molecular mechanisms that mediate TLR signalling is reviewed.
Journal ArticleDOI
Osteoclast differentiation and activation
TL;DR: Discovery of the RANK signalling pathway in the osteoclast has provided insight into the mechanisms of osteoporosis and activation of bone resorption, and how hormonal signals impact bone structure and mass.

Osteoprotegerin Ligand Is a Cytokine that Regulates Osteoclast Differentiation and Activation
David L. Lacey,Emma Timms,Hong-Lin Tan,Michael J. Kelley,Colin R. Dunstan,Tim Burgess,Robin Elliott,Anne Colombero,Gary Elliott,S. Scully,Hailing Hsu,John K. Sullivan,Nessa Hawkins,E. Davy,C. Capparelli,Alana Eli,Yi-xin Qian,Steve Kaufman,Ildiko Sarosi,Victoria Shalhoub,Giorgio Senaldi,Jane Guo,John M. Delaney,William J. Boyle +23 more
TL;DR: The effects of OPGL are blocked in vitro and in vivo by OPG, suggesting that OPGl and OPG are key extracellular regulators of osteoclast development.

Tarpley,P Derby,Richard Lee,William J. Boyle +29 more
TL;DR: Data show that OPG can act as a soluble factor in the regulation of bone mass and imply a utility for OPG in the treatment of osteoporosis associated with increased osteoclast activity.
Journal ArticleDOI
Osteoclast differentiation factor is a ligand for osteoprotegerin/osteoclastogenesis-inhibitory factor and is identical to TRANCE/RANKL

TL;DR: In this article, a membrane-bound osteoclast differentiation factor (ODF) was found to induce OCL formation from osteoblasts/stromal cells in the presence of bone-resorbing factors.
