Safety and Efficacy of Denosumab Vs Ibandronate in Postmenopausal Women Sub-Optimally Treated with Daily or Weekly Bisphosphonates: A Randomized, Open-Label Study
Background/Purpose: Denosumab, a fully human monoclonal antibody that specifically targets RANKL to inhibit osteoclast formation, function, and survival, reduces risk for vertebral, non-vertebral, and hip…Abstract Number: 1962 • 2012 ACR/ARHP Annual Meeting
The Specific Role of Glutaredoxin2 Isoform b (Glrx2b) in RANKL-Induced Osteoclastogenesis Through Activation of the p38-MAPK Signaling Pathway
Background/Purpose: Recently, reactive oxygen species (ROS) and antioxidant enzymes were shown to be closely associated with RANKL-mediated osteoclast differentiation. Although glutaredoxin2 (Glrx2) plays a role…Abstract Number: 1968 • 2012 ACR/ARHP Annual Meeting
The Specific Role of Vesicle-Associated Membrane Protein-Associated Protein B/C(VapB) As a Regulator of Osteoclastogenesis Via Modulation of Phospholipase Cã(PLCã2-Ca2+-NFAT Signaling
Background/Purpose: Recently, Vesicle-Associated Membrane Protein-Associated Protein B/C(VapB) has been shown to regulate calcium homeostasis in myotrophic lateral sclerosis. Calcium signalingis also important in metabolic bone diseases,…Abstract Number: 1977 • 2012 ACR/ARHP Annual Meeting
Relationship Between Baseline Bone Turnover Marker Levels and Bone Mineral Density Changes in Men with Low Bone Mineral Density Receiving Denosumab or Placebo
Background/Purpose: Denosumab, a fully human monoclonal antibody to RANKL, has been shown to increase bone mineral density (BMD) in postmenopausal women with high or low…Abstract Number: 1281 • 2012 ACR/ARHP Annual Meeting
IL-6 Signaling Inhibition Improves Abnormal Bone Homeostasis in Active Rheumatoid Arthritis
Background/Purpose: Tocilizumab (TCZ) is a humanized monoclonal anti-IL-6 receptor antibody. TCZ has demonstrated efficacy in moderate to severe active rheumatoid arthritis (RA) with inadequate clinical…Abstract Number: 1207 • 2012 ACR/ARHP Annual Meeting
Impact of Anti Tumor Necrosis Factor-Alpha Therapy in Rheumatoid Arthritis On Osteoclast Activation and B Cells
Background/Purpose: Serum receptor activator of NFkB ligand (RANKL) and its natural decoy receptor, osteoprotegerin (OPG), play key roles in osteoclast activation. In a group of…Abstract Number: 726 • 2012 ACR/ARHP Annual Meeting
Dynamic in Vivo Imaging of Th17-Mediated Osteoclastic Bone Resorption in Live Bones by Using Intravital Multiphoton Microscopy
Background/Purpose: Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by joint synovial inflammation and progressive cartilage/bone destruction. Although various kinds of cell types, such…Abstract Number: 45 • 2012 ACR/ARHP Annual Meeting
The Effects of Apremilast On Osteoclasts, Osteoblasts, and Osteocytes
Background/Purpose: Apremilast (APR), a small molecule specific inhibitor of phosphodiesterase 4, works intracellularly to modulate pro- and anti-inflammatory mediator production in both immune and non-immune…Abstract Number: 2666 • 2012 ACR/ARHP Annual Meeting
A Link Between B Cells and Bone Erosion in RA: RANKL Production by Memory B Cells
Background/Purpose: Rheumatoid arthritis (RA) is a systemic inflammatory disorder that often leads to joint damage. Several lines of evidence suggests the role of B cells…
