Functionally Distinct Fibroblast Populations in Systemic Sclerosis Skin Revealed by Explant Tissue Characterization and Single-cell RNAseq
Background/Purpose: Traditional studies of skin fibroblasts in SSc focus on the early "migratory" fibroblast population derived from explant culture of skin biopsies. Single-cell RNAseq has…Abstract Number: 1184 • ACR Convergence 2022
Intracellular Calcium Signals Regulate the Pro-fibrotic Phenotype of Scleroderma Fibroblasts via Calcium/calmodulin-dependent Kinase II
Background/Purpose: We performed an in-depth analysis of the involvement of histone reader bromodomain extra-terminal proteins (BETs) in scleroderma (SSc) fibrosis and showed that JQ1, a…Abstract Number: 1185 • ACR Convergence 2022
Interleukin-11 Promotes Fibrosis Through Classic and Trans-signaling Pathway in Systemic Sclerosis
Background/Purpose: Interleukin-11 (IL-11) was found significantly upregulated in Systemic sclerosis (SSc), the aim of this study is to explore the pathological role of IL-11 and…Abstract Number: 1624 • ACR Convergence 2022
Blocking IL-1, IL-33 and IL-36 Signaling with the Anti-IL1RAP Antibody mCAN10 Ameliorates Inflammation and Fibrosis in Preclinical Models of Systemic Sclerosis
Background/Purpose: The IL-1 receptor accessory protein (IL1RAP) is a co-receptor required for signaling through the IL-1, IL-33, and IL-36 receptors. IL1RAP-dependent signaling has been implicated…Abstract Number: 1365 • ACR Convergence 2021
Release of High-Mobility Group Box-1 After an Raynaud’s Attack Potentially Leads to Fibroblast Activation and Interferon-γ Induced Protein-10 Production in Systemic Sclerosis
Background/Purpose: Raynaud’s Phenomenon (RP) leading to repetitive ischaemia and reperfusion (IR) stress, is the first recognisable sign of systemic sclerosis (SSc). Although RP has been…Abstract Number: 0542 • ACR Convergence 2021
Functional Characterization of Glycoprotein Nonmetastatic Melanoma Protein B in Scleroderma Fibrosis
Background/Purpose: Glycoprotein nonmetastatic melanoma protein B (GPNMB) is widely expressed on stromal cells and immune cells. It is involved in various cell functions such as…Abstract Number: 0544 • ACR Convergence 2021
Targeting CD13/aminopeptidase N as a Novel Therapeutic Approach for Scleroderma Fibrosis
Background/Purpose: Aminopeptidase N, also known as CD13, is a Zn2+-dependent membrane bound ectopeptidase widely expressed in mammalian cells including rheumatoid arthritis (RA) fibroblast-like synoviocytes (FLS),…Abstract Number: 0551 • ACR Convergence 2021
Metabolic Intermediate Dimethyl-Alpha-Ketoglutarate Is a Novel Repressor of Pathogenic Myofibroblast Reprogramming and Skin Fibrosis in Systemic Sclerosis
Background/Purpose: Metabolic perturbations drive fibroblast-to-myofibroblast reprogramming and tissue fibrosis. Restoring perturbed metabolism might represent a new antifibrotic strategy. Here we explored the capacity of dimethyl-alpha-ketoglutarate…Abstract Number: 0553 • ACR Convergence 2021
IgG from Systemic Sclerosis Patients Induce a Profibrosing and Serotype-dependent Phenotype in Normal Dermal Fibroblast: A Multi-omics Study
Background/Purpose: Antinuclear antibodies are frequent in systemic sclerosis (SSc). While recognized as potent biomarkers, their pathogenic role is much more debated. This study explored the…Abstract Number: 0557 • ACR Convergence 2021
The Beta Secretase BACE1 Induces Systemic Sclerosis (SSc) Fibroblast Activation Through the Regulation of the Pro-Fibrotic Notch Signalling Pathway
Background/Purpose: Extensive work in the Alzheimer’s field has shown BACE1 plays an important role in amyloid beta processing. Additionally, there is evidence showing BACE1 regulating…Abstract Number: 0559 • ACR Convergence 2021
Targeting NNMT as a Novel Metabolic Approach to Treat Systemic Sclerosis
Background/Purpose: Fibrosis, the hallmark of systemic sclerosis (SSc), is associated with metabolic and epigenetic alterations that are incompletely characterized. Our laboratory had previously implicated dysregulated…Abstract Number: 1001 • ACR Convergence 2021
Exosomes Mediate a Cooperative Mechanism of Macrophage/Fibroblast Activation in Systemic Sclerosis
Background/Purpose: Prior work demonstrates that macrophages (MØs) from patients with Systemic Sclerosis (SSc) produce fibrotic and pro-inflammatory mediators and that cocultured MØs and SSc fibroblasts…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: 1912 • ACR Convergence 2020
