Microbiota-induced Intestinal Barrier Dysfunction Initiates the Shuttling of Immune Cells from the Gut to the Joints
Background/Purpose: While it is known that microbial dysbiosis is associated with the onset of rheumatoid arthritis, mechanistic insights how it facilitates the development of arthritis…Abstract Number: 1491 • ACR Convergence 2020
Association of a Leaky Gut but Not Microbial Dysbiosis with Obesity-related OA: A Translational Study
Background/Purpose: To test the hypothesis that an altered gut microbiota (dysbiosis) plays a causal role in the obese OA phenotype (obesity with both hand and…Abstract Number: 0709 • ACR Convergence 2020
Anatomical Distribution of Mrgprd-expressing Nonpeptidergic C-fibers in the Mouse Knee
Background/Purpose: The voltage-gated sodium channel, NaV1.8, marks the majority of C-fiber nociceptors. We have used NaV1.8 tdTomato reporter mice to describe the nociceptive innervation of…Abstract Number: 1519 • ACR Convergence 2020
Interleukin-17D, a Cytokine Derived from Stromal Cells, Attenuates Joint Inflammation
Background/Purpose: Interleukin(IL)-17D is a little recognized member of the IL-17 family of cytokines. While the activities of IL-17A and IL-17F in the pathogenesis of spondyloarthritis…Abstract Number: 0739 • ACR Convergence 2020
Toll-like Receptor Inhibitor Peptide Improves the Clinical, Immunologic, and Pathologic Manifestations of Systemic Lupus Erythematosus
Background/Purpose: Toll-like receptors (TLRs) are a type of protein that plays a major role in the innate immune system. In recent years, several studies have…Abstract Number: 1524 • ACR Convergence 2020
Interstitial Lung Disease, Kidney Inflammation and Myositis Are Induced by Transfer of PBMC Derived from Systemic Sclerosis Patients into Rag2-/-/ IL2rg-/- mice
Background/Purpose: To explore the pathogenic potential of lymphocytes in systemic sclerosis (SSc) and granulomatosis with polyangiitis (GPA), a humanized mouse model was generated by transferring…Abstract Number: 0740 • ACR Convergence 2020
Card9 Promotes Th17-mediated Arthritis and Spondylitis via Control of Acute Pathogenic Neutrophil Responses in SKG Mice
Background/Purpose: Caspase recruitment domain-containing protein 9 (CARD9) is an intracellular signal transduction molecule that mediates antimicrobial responses following activation of C-type lectin receptors (ie. Dectin-1) by…Abstract Number: 1852 • ACR Convergence 2020
Intestinal Permeability in the Adjuvant Induced Arthritis Model: Preliminary Study and Impact of NSAIDs
Background/Purpose: The gut is no longer considered as a simple element associated with spondyloarthritis but as a real actor of the disease. In patients with…Abstract Number: 0742 • ACR Convergence 2020
Effect of IA OnabotulinumtoxinA and Vanilloids on Substance P and Neurokinin 1 Receptor Expression in the Dorsal Root Ganglia of Mice with Monoarthritis
Background/Purpose: Neurotoxins are increasingly being proposed as analgesics for arthritis pain. Phase II and III clinical trials have shown efficacy but with potential toxicities such…Abstract Number: 1906 • ACR Convergence 2020
Hsp90 Inhibition Effectively Prevents Progression of Dermal Fibrosis and Induces Regression of Established Bleomycin-Induced Dermal Fibrosis
Background/Purpose: Our previous study demonstrated that Heat shock protein 90 (Hsp90) is overexpressed in the skin of patients with systemic sclerosis (SSc), in cultured SSc…Abstract Number: 0836 • ACR Convergence 2020
SH3BP2 Deficiency Ameliorates Murine Systemic Lupus Erythematosus
Background/Purpose: The adaptor protein, Src homology 3 domain-binding protein 2 (SH3BP2), is widely expressed in immune cells, such as myeloid cells, B cells, and T…Abstract Number: 1915 • ACR Convergence 2020
Leptin Plays a Critical Role in Modulating Dermal Adipose Tissue, Inflammation and Skin Fibrosis
Background/Purpose: We previously demonstrated that systemic sclerosis (SSc) patients have substantial reduction in dermal white adipose tissue (dWAT) which correlates with skin fibrosis. In animal…Abstract Number: 0840 • ACR Convergence 2020
Amelioration of Immune Complex-Mediated Glomerulonephritis via CD6 Modulation
Background/Purpose: CD6 is a co-stimulatory receptor, predominantly expressed on T cells, that binds to activated leukocyte cell adhesion molecule (ALCAM), a ligand expressed on antigen-presenting…Abstract Number: 1972 • ACR Convergence 2020
NGF-Responsive Neurons Are Sensitized in Experimental Osteoarthritis
Background/Purpose: Nerve growth factor (NGF) is under investigation as a promising target for osteoarthritis (OA) pain. NGF exerts its potent pro-algesic effects through sensitization of…Abstract Number: 0843 • ACR Convergence 2020
Rab4A Activation Predisposes to Hepatitis in Spontaneous and Pristane-Induced Mouse Models of Systemic Lupus Erythematosus
Background/Purpose: HRES-1/Rab4 or Rab4A, a GTPase responsible for mitochondrial oxidative stress1 and activation of the mechanistic target of rapamycin2, is overexpressed in T cells of…
