Circulating CD4+CD161+ T Lymphocytes Are Increased In Seropositive Arthralgia Patients But Decreased In Patients With Newly Diagnosed Rheumatoid Arthritis
Background/Purpose: Improved understanding of the immune events discriminating between seropositive arthralgia and clinical synovitis is of key importance in rheumatology research. Ample evidence suggests a…Abstract Number: 1646 • 2013 ACR/ARHP Annual Meeting
Alterations In Circulating T Follicular Helper Cells and T Regulatory Cells In Autoimmune Rheumatic Diseases Treated With B Cell Depletion Therapy: Rituximab
Background/Purpose: Granulomatosis with polyangiitis (GPA) and systemic lupus erythematosus (SLE) are autoimmune rheumatic diseases which develop due to failure of immune self-tolerance. T follicular helper…Abstract Number: 1647 • 2013 ACR/ARHP Annual Meeting
An Altered Frequency Of Circulating Follicullar T Helper Cell Counterparts and Their Subsets Is Associated With Increased Circulating Plasmablasts In Seropositive RA Patients
Background/Purpose: Follicular T helper (Tfh) cells, a CD4 T helper subset localized in lymphoid organs, help B cell differentiation and function. Circulating CD4 T cells…Abstract Number: 1648 • 2013 ACR/ARHP Annual Meeting
PD-1+CD45RBlo122lo Autoantibody-Inducing CD4 T Cells (aiCD4 T cells) As a Key In The Pathogenesis Of Systemic Lupus Erythematosus (SLE)
