Development of Engineered Smith-Specific Regulatory T Cells to Treat Lupus Nephritis
Background/Purpose: Regulatory T cells (Tregs) play an important role in maintaining immune system homeostasis. Antigen-specific Tregs potently and specifically suppress autoreactivity, suggesting their potential to…Abstract Number: 0068 • ACR Convergence 2023
Anti-TNFR2 VHH Agonistic Antibodies Promote and Stabilize Treg Immunosuppressive Activity
Background/Purpose: Regulatory T cells (Treg) are a population of lymphocytes with immunosuppressive function. Activation and expansion of Treg is an attractive therapeutic approach for autoimmune…Abstract Number: 0089 • ACR Convergence 2023
Pre-Clinical Characterization of MTX-101, a Novel Bispecific CD8 Treg Modulator with the Potential to Restore CD8 Treg Functions in Patients with Rheumatological Autoimmune Diseases
Background/Purpose: In healthy individuals, CD8 Treg activation leads to selective elimination of aberrantly activated self-reactive CD4 T cells to maintain immune balance. The CD8 Treg…Abstract Number: 0091 • ACR Convergence 2023
Impaired X-Chromosome Inactivation Maintenance in T Cells Is Associated with Features of Reduced Disease Severity in a Toll-Like Receptor 7-Driven Model of Systemic Autoimmunity
Background/Purpose: Many systemic autoimmune rheumatic diseases, including systemic lupus erythematosus (SLE), Sjögren's syndrome, and systemic sclerosis are highly female-biased. Although these diseases are more prevalent…Abstract Number: 0423 • ACR Convergence 2023
Detection of Citrullinated Proteins Recognized by a Novel Chimeric Antigen Receptor TregTherapy in Both Synovial Fluid and Serum from Patients with Rheumatoid Arthritis
Background/Purpose: Rheumatoid arthritis (RA) is one of the most common autoimmune diseases and despite many therapeutic options, an unmet medical need persists for novel therapies…Abstract Number: 0581 • ACR Convergence 2022
Mutants Improving Stability Enhance the Potency of Treg-Selective IL-2 Mutein for the Treatment of Autoimmune Disorders
Background/Purpose: Low-dose IL-2 with enhanced sensitivity to Treg cells has been proved to be safe and efficacious in multiple autoimmune disorders (AIDs) including SLE, RA,…Abstract Number: 0646 • ACR Convergence 2022
Modulation of Type I IFN Production and Regulatory T Cells by the PKGI/ROCK Signaling Pathway
Background/Purpose: IFNα is a pathogenic factor in SLE. The PRKG1 rs7897633 variant has been previously identified as the top hit in European ancestry patients with…Abstract Number: 0649 • ACR Convergence 2022
Phosphofructokinase P Fine-Tunes T Regulatory Cell Metabolism, Function and Stability in Systemic Autoimmunity
Background/Purpose: Systemic lupus erythematosus (SLE) is characterized by a defective T regulatory (Treg) cell compartment which participate in immune dysregulation. Although the underlying mechanism are…Abstract Number: 0666 • ACR Convergence 2022
HRES-1/Rab4 Controls the Overexpression of CD38 and Depletion of IL-2 in CD4+ T Cells; Potential Involvement in Proinflammatory Lineage Development in SLE
Background/Purpose: HRES-1/Rab4 (Rab4A) is a small GTPase that is overexpressed in SLE patient T cells1,2, mediates the enhanced recycling of CD3 and CD4 cell surface…
