Three Distinct Transcriptional Profiles of Monocytes Correlate with Disease Activity in SSc Patients
Background/Purpose: Patients with SSc display a complex clinical phenotype.Our group has made important contributions to an emerging understanding of monocytes and macrophages as central to…Abstract Number: 1890 • ACR Convergence 2021
Cellular Origin and Functions of Osteoclasts in Inflammatory Arthritis
Background/Purpose: Inflammatory arthritis (IA) is an autoimmune disease targeting multiple joints and characterized by joint destruction caused by osteoclasts (OC), leading to physical disability. However,…Abstract Number: 0022 • ACR Convergence 2021
The Effects of MAA-Modified and/or Citrullinated Proteins on Calcium Influx and Peptidyl Arginine Deiminase (PAD) Expression in Macrophage
Background/Purpose: Expressed in synovial fluid mononuclear and other inflammatory cells, peptidyl arginine deiminase (PAD) catalyzes post-translational citrullination of synovial proteins in a calcium (Ca2+)-dependent manner.…Abstract Number: 0040 • ACR Convergence 2021
M1-M2 Polarization by CTLA4-Ig (Abatacept) on Cultured Circulating Monocytes from Rheumatoid Arthritis Patients and Healthy Subjects

The Impact of Macrophages Stimulated with Malondialdehyde-Acetaldehyde And/or Citrulline Modified Proteins on Fibroblasts Activation
Background/Purpose: In rheumatoid arthritis (RA), chronic synovial inflammation is accompanied by fibrotic responses that together lead to pannus formation and progressive joint damage. Exposure to…Abstract Number: 0513 • ACR Convergence 2021
Spirulina Activates IFNγ via TLR4 in Dermatomyositis Skin and Peripheral Blood
Background/Purpose: Our group has previously shown that Spirulina, a popular herbal supplement with purported immune boosting effects, is temporally associated with dermatomyositis (DM) onset and…Abstract Number: 0942 • ACR Convergence 2021
Transcriptional Regulation of Synovial Macrophages in the Aging Joint
