Thy1 Is a Positive Regulator of Osteoblast Differentiation and Modulates Bone Homeostasis in Obese Mice
Background/Purpose: Thy1 (CD90) is a glycosylated, glycophosphatidylinositol (GPI)-anchored membrane protein originally identified as a marker for mouse T cells but subsequent reports noted expression on…Abstract Number: 323 • 2016 ACR/ARHP Annual Meeting
Effect of 10 Years of Denosumab Treatment on Bone Histology and Histomorphometry in the Freedom Extension Study
Background/Purpose: Denosumab (DMAb) has been associated with low incidence of spine and non-spine, including hip, fractures through 10 years of treatment (Bone ASBMR 2015). Questions…Abstract Number: 1097 • 2016 ACR/ARHP Annual Meeting
Tankyrase Regulates Osteoclastogenesis Via SH3BP2
Background/Purpose: Tankyrase is a poly (ADP-ribose) polymerase that leads to ubiquitination and degradation of target proteins. Axin, a regulatory protein of Wnt/β-catenin signaling, is one…Abstract Number: 2137 • 2016 ACR/ARHP Annual Meeting
Subchondral Bone Structure and Pain Behaviors in Collagenase Induced Noninflammatory Monoarthritis in Mice
Background/Purpose: Bone histomorphometry can define OA changes in rodents and in Antigen-Induced arthritis in rats. We previously found that pain from inflammatory monoarthritis in mouse…Abstract Number: 1941 • 2015 ACR/ARHP Annual Meeting
Senescent T-Cells Expedite RANKL-Dependent Bone Loss in Rheumatoid Arthritis
Background/Purpose: To study the influence of senescent CD28-T-cells on systemic osteoporosis in rheumatoid arthritis (RA) and patients with primary osteoporosis. Methods: Prospective, cross-sectional study on…Abstract Number: 2084 • 2015 ACR/ARHP Annual Meeting
Dendritic Cell-Specific Transmembrane Protein (DC-STAMP) Modulates Bone Resorption in Inflammatory Arthritis and Fracture Repair
Background/Purpose: Osteoclasts (OC) direct pathologic bone resorption in osteoporosis and inflammatory arthritis. We previously demonstrated that DC-STAMP (Dendritic Cell-Specific Transmembrane protein), a 7-pass transmembrane protein,…Abstract Number: 2207 • 2015 ACR/ARHP Annual Meeting
Interleukin-32γ Exhibited Protective Effects on Osteoporosis
Background/Purpose: Interleukin-32 (IL-32) has been known to be implicated in the pathogenesis of various inflammatory diseases. Osteoporosis, characterized by low bone density and increases the…Abstract Number: 2568 • 2015 ACR/ARHP Annual Meeting
The Osteoimmunological Mechanistic Basis of Low-Dose Radiotherapy in TNF Driven Arthritis
