The Minor Protective Allele at rs1876453 Is Associated with Increased Age of Onset of Systemic Lupus Erythematosus
Background/Purpose: Systemic lupus erythematosus (SLE) is a clinically heterogenous autoimmune disease characterized by autoantibody- and complement-mediated inflammatory damage to multiple organ systems. We previously showed…Abstract Number: 0778 • ACR Convergence 2020
Bacterial Families Lachnospiraceae/Ruminococcaceae Are Immunologically Targeted in Individuals At-risk for RA and a Specific Strain Is Arthritogenic in Monocultured Gnotobiotic Mice
Background/Purpose: Circulating autoantibodies, including anti-CCP and RF, develop years before physical manifestations of rheumatoid arthritis (RA), with several lines of evidence suggesting that these autoantibodies…Abstract Number: 1532 • ACR Convergence 2020
The Non-psychotropic Phytocannabinoids Cannabigerol and Tetrahydrocannabinolic Acid Inhibit Rheumatoid Arthritis Synovial Fibroblast Function by Targeting the Wasabi Receptor TRPA1
