Osteoblasts and osteoclasts are involved in bone formation and resorption. RANK and RANKL [receptor activator of nuclear factor kappaB (ligand)], two cytokine-like proteins of the tumor necrosis factor superfamily, are localized on these bone cells and are crucial for the regulation of osteoclastic cell differentiation from hematopoietic precursors and also for the upregulation of mature osteoclasts mediated by cell-to-cell contact and a subsequent cascade of diverse intracellular signaling… 

Immunohistological identification of receptor activator of NF-κB ligand (RANKL) in human, ovine and bovine bone tissues

TLDR
The result strongly suggests the crucial involvement of osteocytes in terms of orchestrating bone remodelling by influencing differentiation and activation of osteoclasts in the long processes of osteocyte remodelling.

Osteoclastogenesis during mouse tooth germ development is mediated by receptor activator of NFΚ-B ligand (RANKL)

TLDR
Observations suggest that osteoclastogenesis in the alveolar bone, which is essential for the accommodation of normal tooth development, is mediated by RANK-RANKL signaling.

Expression and role of RANKL in periodontal ligament cells during physiological root-resorption in human deciduous teeth.

TLDR
Results indicate that PDL cells during the root-resorbing state express RANKL but decrease OPG expression, indicating that expression of RankL likely participates in odontoclastogenesis and activates physiological root resorption.

High expression levels of receptor activator of nuclear factor-kappa B ligand associated with human chronic periodontitis are mainly secreted by CD4+ T lymphocytes.

TLDR
It is demonstrated that gingival CD4(+) T cells are the main cells responsible for higher levels of RANKL observed in human chronic periodontitis patients, and spontaneous and lipopolysaccharide- and phytohemagglutinin-stimulated RankL synthesis were higher in patients than controls.

Immunohistochemical localization of RANK, RANKL and OPG in healthy and arthritic canine elbow joints.

TLDR
The RANK-RANKL-OPG system is active in bone remodeling in dogs and a surplus of molecules promoting osteoclastogenesis was evident and is indicative of an imbalance between the mediators regulating bone resorption and bone formation.

Physiological and Pathological Bone Resorption New Molecules in the Tumor Necrosis Factor Ligand and Receptor Superfamilies with Importance for

TLDR
The critical roles in osteoclast differentiation played by RANKL, RANK, and OPG, three novel members of the tumor necrosis factor ligand and receptor superfamilies are revealed, likely to provide a molecular basis for the development of new drugs for the treatment of diseases with excess or deficient osteoclastic bone resorption.

Receptor activator of NF-kappaB ligand (RANKL) and CD 31 expressions in chronic periodontitis patients before and after surgery

TLDR
RANKL-positive cells were widely distributed in periodontitis patients giving only partial support to the hypothesis that RANKL expression is restricted to T- and B-cell activation.

The Cytolethal Distending Toxin Induces Receptor Activator of NF-κB Ligand Expression in Human Gingival Fibroblasts and Periodontal Ligament Cells

TLDR
Investigation of the effect of A. actinomycetemcomitans on the expression of RANKL and OPG in human gingival fibroblasts and periodontal ligament cells found it necessary to note that Cdt is crucial for this induction and may therefore be involved in the pathological bone resorption during the process of localized aggressive periodontitis.

Expressions of RANKL/RANK and M-CSF/c-fms in root resorption lacunae in rat molar by heavy orthodontic force.

TLDR
RANKL/RANK and M-CSF/c-fms systems may be involved in the process of root resorption by heavy orthodontic force.
