PD-1 Signaling Interferes with OX40L to Alter the Suppressive Function and Proliferation of CD4+ Regulatory T Cells in Lupus Mice
Background/Purpose: In systemic lupus erythematosus (SLE), the dysregulated production of autoantibodies is a consequence of disrupted T cell homeostasis. Programmed death-1 (PD-1), a negative regulator…Abstract Number: 351 • ACR/ARHP Annual Meeting 2018
Rheumatic Immune-Related Adverse Events in Patients on ANTI-PD-1 Inhibitors: Fasciitis with Myositis Syndrome As a New Rheumatic Complication of Immunotherapy
Background/Purpose: To evaluate the prevalence and type of rheumatic immune-related adverse events (IRAEs) in patients receiving programmed cell death protein-1 (PD-1) inhibitors. Methods: This is…Abstract Number: 2095 • ACR/ARHP Annual Meeting 2017
Traditional Disease Modifying Anti-Rheumatic Drugs (tDMARDs), Hydroxychloroquine (HCQ) and/or Sulfasalazine (SSZ), Are Rapidly Effective in Immune Checkpoint Inhibitors-Induced Inflammatory Arthritis
Background/Purpose: Immune checkpoint inhibitor (ICI) therapy is widely used in the treatment of metastatic melanoma and non-small cell lung cancer and it is under investigation…Abstract Number: 2580 • ACR/ARHP Annual Meeting 2017
Exploiting Inhibition of PD1 Signaling in a Murine Model of Anti-SSA/Ro Associated Congenital Heart Block
Background/Purpose: The most serious manifestation of fetal exposure to maternal anti-Ro antibodies is the development of heart block. This work addresses the hypothesis that fetal…Abstract Number: 2705 • ACR/ARHP Annual Meeting 2017
Aberrant Expression and Function of Human Circulating T Follicular Helper Cells and Its Subsets in IgG4 Related Disease
Background/Purpose: To study the expression and function of T follicular helper cells and its subsets in IgG4-related disease(IgG4-RD). Methods: Flow cytometry was performed to analyze…Abstract Number: 1340 • ACR/ARHP Annual Meeting 2016
Type and Frequency of Immune-Related Adverse Reactions in Patients Treated with Pembrolizumab (Keytruda), a Monoclonal Antibody Directed Against PD-1, in Advanced Melanoma at a Single Institution
Background/Purpose: Although immune checkpoint inhibitors improve survival in patients with melanoma and other cancers, the alterations to the immune system induced by these medications can…Abstract Number: 2925 • ACR/ARHP Annual Meeting 2016
Programmed Cell Death (PD)-1 May Play a Significant Role in the Pathogenesis of Rheumatoid Arthritis
Background/Purpose: PD-1 is a co-inhibitory transmembrane protein with a significant effect on immune regulation. Several studies have shown elevated expression levels of PD-1 on T…Abstract Number: 3042 • ACR/ARHP Annual Meeting 2016
PD-1–Expressing T Cells in GCA Fail to Promote Immune Tolerance Functions
Background/Purpose: The vasculitic lesions in GCA are filled with differentiated effector T cells that sustain granuloma formation, vessel wall restructuring, neoangiogenesis and intimal hyperplasia. Persistent…
