Senescent Synoviocytes in Knee Osteoarthritis Correlate with Disease Biomarkers, Synovitis, and Knee Pain
Background/Purpose: Background/Purpose: Cellular senescence is a natural state in which a cell permanently halts division through upregulation of a set of intracellular proteins including p16INK4A…Abstract Number: 1806 • 2019 ACR/ARP Annual Meeting
Inflammatory Arthritis Induced by Immune Checkpoint Inhibitor Therapy: A Distinct Clinical Entity and Immunologic Phenotype
Background/Purpose: Immune checkpoint inhibitors (ICIs) are being used in the treatment of a variety of malignancies. ICIs target cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4), programmed cell-death…Abstract Number: 1975 • 2019 ACR/ARP Annual Meeting
Fibrates as Drugs with Senolytic and Autophagic Activity for Osteoarthritis Treatment
Background/Purpose: . Increasing evidence suggest that osteoarthritis (OA) is associated with hallmarks of ageing, including cellular senescence or defective autophagy, that could promote disease onset.…Abstract Number: 932 • 2018 ACR/ARHP Annual Meeting
Fibroblasts Senescence Is Observed in Rheumatoid and Osteoarthritic Synovial Tissues and Triggers a Pro-Inflammatory Program Ex Vivo
Background/Purpose: Inflammation is an important component of most age-related disorders. Cellular changes associated to aging are tightly connected with pro-inflammatory mechanisms. The purpose of this…Abstract Number: 1048 • 2018 ACR/ARHP Annual Meeting
Identification of Novel Molecules with Senolytic and Autophagy Activity As Osteoarthritis Therapeutics
Background/Purpose: Disease-modifying treatments for Osteoarthritis (OA) are not available. Aging-related features such as failure of homeostasis mechanisms, including autophagy, cause extracellular matrix damage, chondrocyte senescence…Abstract Number: 1931 • 2017 ACR/ARHP Annual Meeting
Targeting Cartilage Aging As Osteoarthritis Therapeutics By Drug Repurposing
Background/Purpose: Background: Effective treatments for Osteoarthritis (OA) are not available. In aging-related diseases, including OA, failure of cellular homeostasis mechanisms, such as autophagy can cause…Abstract Number: 2945 • 2017 ACR/ARHP Annual Meeting
Incident Hand OA Is Strongly Associated with Reduced Peripheral Blood Leukocyte Telomere Length
Background/Purpose: Hand OA (HOA) is a painful, destructive and deforming polyarticular disorder that impairs an individual’s ability to perform manipulative activities of daily life and…Abstract Number: 1832 • 2016 ACR/ARHP Annual Meeting
Increased Interferon b Expression in Bone Marrow Mediates a Senescent Phenotype and Impaired Production of Immunomodulatory Factors By SLE Mesenchymal Stromal Cells
Background/Purpose: Bone marrow mesenchymal stromal cells (MSCs) are multipotent stem cells that create a special microenvironment for hematopoiesis and immunity. MSCs display robust immunomodulatory properties…Abstract Number: 2132 • 2016 ACR/ARHP Annual Meeting
Deficient Autophagy Induces Premature Senescence in Aging and Osteoarthritis
Background/Purpose: Previous findings indicated that autophagy is defective in Aging and Osteoarthritis (OA). Autophagy is essential to maintain chondrocyte homeostasis by regulating the intracellular macromolecule…Abstract Number: 2142 • 2016 ACR/ARHP Annual Meeting
Identification of Novel Molecules Targeting Cartilage Aging As Osteoarthritis Therapeutics

Circulating CD4+CD28null T-Cells Predict the Occurrence of New Lung Damage in Systemic Lupus Erythematosus (SLE) Patients
Background/Purpose: Peripheral CD4+CD28null T-cells constitute a subset of long-lived cytotoxic CD4+ T-cell with pro-inflammatory functions. This T-cell subpopulation has been reported to be associated with…Abstract Number: 759 • 2015 ACR/ARHP Annual Meeting
Prolactin Level Is Independently Associated with Circulating CD4+CD28null in Systemic Lupus Erythematosus Patients
Background/Purpose: Peripheral CD4+CD28null T-cells are a subset of long-lived cytotoxic CD4+ T-cells with pro-inflammatory functions, and they are increased in autoimmune and cardiovascular diseases. Prolactin…Abstract Number: 1606 • 2015 ACR/ARHP Annual Meeting
Telomere Damage in Rheumatoid Arthritis
Background/Purpose: Production of anti-CCP autoantibodies, the hallmark of rheumatoid arthritis (RA), is dependent on T cell help, positioning T cells into a pinnacle position in…Abstract Number: 1941 • 2015 ACR/ARHP Annual Meeting
Senescent T-Cells Expedite RANKL-Dependent Bone Loss in Rheumatoid Arthritis
