G Protein-coupled Receptor Kinase 5 in Fibrotic Tissue Remodeling
Background/Purpose: G-protein coupled receptor kinase 5, GRK5, is a central regulator of G protein-coupled receptors (GPCRs), a vast family of cell surface receptors involved in…Abstract Number: 0943 • ACR Convergence 2023
Attenuation of Fibroblast Activation and Fibrosis by Adropin in a Hedgehog-Dependent Manner
Background/Purpose: Adropin is a secretory protein encoded by the energy homeostasis - associated (ENHO) gene. Emerging evidence indicate its role in metabolism and energy homeostasis,…Abstract Number: 0945 • ACR Convergence 2023
The Nuclear Receptor TR4 Orchestrates Cytoskeletal Organization in a Gα12/ROCK-dependent Manner to Promote Myofibroblast Differentiation and Tissue Fibrosis in Systemic Sclerosis
Background/Purpose: Members of the superfamily of nuclear receptors have been implicated in inflammatory processes and pathologic tissue remodeling and have emerged as attractive targets for…Abstract Number: 0946 • ACR Convergence 2023
Immunoglobulins G Purified from Systemic Sclerosis Patients Influence Cytoplasmic and Nuclear Proteins Profile in Dermal Fibroblasts
Background/Purpose: Autoantibodies (Aab) are frequent in systemic sclerosis (SSc). While recognized as potent biomarkers, their pathogenic role is unclear. Recently, we showed that immunoglobulins G…Abstract Number: 0948 • ACR Convergence 2023
Nintedanib Alters Fibroblast and Macrophage Diversity in a 3D Skin Model of Systemic Sclerosis (SSc)
Background/Purpose: Systemic Sclerosis (SSc) is a rare autoimmune disease characterized by fibrosis of the skin and internal organs. While the tyrosine kinase inhibitor Nintedanib is…Abstract Number: 0952 • ACR Convergence 2023
Unraveling the Role of MiR-181 in Skin Fibrosis Pathogenesis by Targeting NUDT21
Background/Purpose: Nudix Hydrolase 21 (NUDT21, also known as CFIm25) is a master regulator of alternative polyadenylation. Previous studies have revealed that NUDT21 is significantly decreased…Abstract Number: 0953 • ACR Convergence 2023
Flavin-containing Monooxygenase (FMO3) Links the Gut and Fibrosis in Systemic Sclerosis
Background/Purpose: Trimethylamine (TMA) generated by the gut microbiome is converted into trimethylamine N-oxide (TMAO) via the host enzyme FMO3. The TMA-FMO3-TMAO metaorganismal axis has been…Abstract Number: 0954 • ACR Convergence 2023
Non-canonical WNTA Promotes Cytoskeletal Rearrangement and Integrin Alpha V Clustering via JNK and ROCK to Control the Activation of Latent TGFβ
Background/Purpose: Systemic sclerosis (SSc) is a chronic autoimmune disorder with vasculopathy, inflammation, and fibrosis of the skin and organs. Fibrosis is caused by the abnormal…Abstract Number: 0957 • ACR Convergence 2023
Rationale for Targeting Insulin-like Growth Factor Signalling in Systemic Sclerosis
Background/Purpose: Previous studies have shown that insulin like growth factor (IGF) pathways may promote extracellular matrix deposition and be upregulated in systemic sclerosis (SSc). Teprotumumab,…Abstract Number: 0960 • ACR Convergence 2023
MiR-3606-3p Alleviates Skin Fibrosis by Suppressing Fibroblast Inflammation and Migration via Inhibiting GAB1 and ITGAV
Background/Purpose: Systemic sclerosis (SSc) and keloid are typical skin fibrotic diseases with unclear epigenetic mechanisms and clinical targets. As an important epigenetic regulatory factor, microRNAs…Abstract Number: 0085 • ACR Convergence 2023
Fibroblasts Promote Upregulation of Cannabinoid Type 2 Receptor on Inflammatory Cells in Dermatomyositis
Background/Purpose: Dermatomyositis (DM) is a chronic, systemic autoimmune disease affecting the skin, muscle, and lungs. The activation of CB2R has been shown to reduce several,…Abstract Number: 0963 • ACR Convergence 2023
Anti-Topoisomerase Antibody in dcSSc: Unravelling Its Intracellular Effects in Systemic Sclerosis
Background/Purpose: The presence of autoantibodies, especially directed towards topoisomerase I (ATA), in diffuse cutaneous Systemic Sclerosis (dcSSc) is known to be associated with severe clinical…Abstract Number: 0787 • ACR Convergence 2023
Understanding Distinct Resident and Migratory Fibroblast Populations in Systemic Sclerosis Skin Through Single-cell RNAseq and Immunohistochemistry
Background/Purpose: We previously described distinct migratory and resident fibroblast populations from lesional skin biopsies in SSc patients. Both populations are profibrotic compared with those from…Abstract Number: 0964 • ACR Convergence 2023
Systemic Sclerosis (SSc) Dermal Fibroblasts Show Shortened Primary Cilia Due to Aberrant Aurora a Kinase Activation Independently of Transforming Growth Factor β Signalling
Background/Purpose: Systemic Sclerosis (SSc) is an autoimmune disorder characterised by abnormal activation of tissue fibroblasts, resulting in tissue and vascular fibrosis of the skin and…Abstract Number: 007 • 2023 Pediatric Rheumatology Symposium
Single Cell RNA Sequencing Analysis of the Skin to Evaluate the Effect of Autologous Stem Cell Transplant on Fibroblast Populations in Juvenile Onset Systemic Sclerosis
Background/Purpose: Juvenile systemic sclerosis (JSSc) is a rare autoimmune disease associated with high morbidity. Inflammatory driven multi-organ fibrosis is similar to adult-onset SSc, with 40%…
