The role of RANK ligand/osteoprotegerin in rheumatoid arthritis

Abstract: In the complex system of bone remodeling, the receptor activator of nuclear factor κB ligand (RANKL)/osteoprotegerin (OPG) pathway is the coupling factor between bone formation and bone resorption. RANKL binds to the RANK receptor of pre-osteoclasts and mature osteoclasts and stimulates their activation and differentiation. The production of RANKL/OPG by osteoblasts is influenced by hormones, growth factors and cytokines, which each have a different effect on the production of RANKL and OPG. Ultimately, the ba… Show more

“…[37][38][39] Ultimately, the degree of osteoclast differentiation and activation is dictated by the balance between OPG and RANKL within the bone microenvironment. 40 Here we demonstrate that whereas CIAchallenged, and even naïve, fXIIIA 2/2 mice displayed molecular changes consistent with reduced osteoclast differentiation and osteoclast numbers (ie, reduced mRNA levels of RANKL and TRAP), fibrinogen-deficient mice did not show the same molecular changes. Additionally, inflammatory cytokines, such as TNFa, IL-6, and IL-1b, synergize with RANKL to promote osteoclast differentiation and activation.…”

“…Dlatego też Geusens i wsp. [18] stwierdzili, że w ocenie aktywności procesu zapalnego oraz postępu leczenia najlepsze rezultaty daje badanie wzajemnego stosunku OPG do RANKL. W ostatnich latach wykazano również, że jednym z mechanizmów działania terapeutycznego leków obecnie stosowanych w RZS jest prewencja przystawowej resorpcji kości przez wpływ na układ OPG-RANKL-RANK.…”

“…W ostatnich latach wykazano również, że jednym z mechanizmów działania terapeutycznego leków obecnie stosowanych w RZS jest prewencja przystawowej resorpcji kości przez wpływ na układ OPG-RANKL-RANK. Stwierdzono, że leki biologiczne, takie jak: infliksymab i etanercept, zwięk-szają ekspresję OPG w stawach chorych na RZS [18]. Infliksymab ponadto zmniejsza produkcję RANKL i pulę preosteoklastów oraz hamuje dojrzewanie komórek dendrytycznych [15].…”
