Osteoimmunology

[3][4] Osteoimmunology also studies the shared components and mechanisms between the two systems in vertebrates, including ligands, receptors, signaling molecules and transcription factors.

Over the past decade, osteoimmunology has been investigated clinically for the treatment of bone metastases, rheumatoid arthritis (RA), osteoporosis, osteopetrosis, and periodontitis.

Some important cytokines that are produced by the immune system, including RANKL, M-CSF, TNFa, ILs, and IFNs, affect the differentiation and activity of osteoclasts and bone resorption.

[9][10] Clinical osteoimmunology is a field that studies a treatment or prevention of the bone related diseases caused by disorders of the immune system.

[11][12] The second is an indirect effect on osteoclast differentiation and activity by the secretion of inflammatory cytokines such as IL-1, IL-6, TNFa, in synovium of RA, which increase RANKL signaling and finally bone destruction.
