Role of T Follicular Helper Cells and T Peripheral Helper Cells in the Activation of B Cells in Sjögren Syndrome
Background/Purpose: Primary Sjögren's Syndrome (pSS) is a rare systemic autoimmune disease characterized by a dysregulation of cellular and humoral immunity, leading to a hyper-activation of…Abstract Number: 109 • 2019 ACR/ARP Annual Meeting
Targeting CD6 Expression Attenuates T Cell Activity in Murine Collagen Induced Arthritis
Background/Purpose: CD6, an important regulator of T cell function, interacts with the ligands CD166 and CD318. We previously examined CD318 expression on synovial tissues (STs)…Abstract Number: 2421 • 2019 ACR/ARP Annual Meeting
Circulating CCR7loPD-1hi Follicular Helper T Cells Indicate Disease Activity and Glandular Inflammation in Patients with Primary Sjögren’s Syndrome
Background/Purpose: Since primary Sjögren’s syndrome (pSS) is an autoummune disease of B cell hyperactivity and pathologic autoantibody response, follicular helper T (Tfh) cells and follicular…Abstract Number: 110 • 2019 ACR/ARP Annual Meeting
Bioinformatics Analysis of Transcriptomics Data Reveals That SRSF1 Is a Novel Molecular Brake for the T Cell Activation Program and Controls Key Cytokine Signaling Genes Implicated in Systemic Lupus Erythematosus
Background/Purpose: T cells from systemic lupus erythematosus (SLE) patients exhibit a hyperactive phenotype with defects in homeostasis, signaling and cytokine production. By discovery approaches, we…Abstract Number: 2816 • 2019 ACR/ARP Annual Meeting
An Expanded Granzyme K+ CD8 T Cell Population Induces Inflammatory Responses in Rheumatoid Arthritis Synovium
Background/Purpose: CD8 T cells represent nearly half of T cells in inflamed synovium from patients with rheumatoid arthritis (RA). Research to date has focused on…Abstract Number: 111 • 2019 ACR/ARP Annual Meeting
The Transcription Factor STAT3 Regulates Pathogenic Th17 Responses in Autoimmune Disease via Noncanonical Roles
Background/Purpose: The Th17 lineage of CD4 T cells drives autoimmune diseases such as RA, SLE, IBD, and MS. The JAK2/STAT3 signaling pathway is required for…Abstract Number: 2818 • 2019 ACR/ARP Annual Meeting
Differences in the Phenotypic Landscape and Antigen Specificity of CD4+ T Cells Are Present in CCP+ Subjects Before the Onset of Rheumatoid Arthritis
Background/Purpose: The “Targeting Immune Responses for Prevention of RA” (TIP-RA) collaboration studies individuals at high risk for developing rheumatoid arthritis (RA) because of serum anti-citrullinated…Abstract Number: 113 • 2019 ACR/ARP Annual Meeting
In Vitro Characterization of the Effect of Cenerimod, a Potent and Selective Sphingosine 1-Phosphate Receptor 1 (S1P1) Modulator, on S1P1 Receptor Expression, Receptor Internalization, and Migration of Primary Human T Cells in the Presence or Absence of Glucocorticoids
Background/Purpose: Cenerimod is a potent, selective, and orally active sphingosine 1-phosphate receptor 1 (S1P1) modulator that is currently being evaluated in a Phase 2b study…Abstract Number: 2819 • 2019 ACR/ARP Annual Meeting
The Transcription Factor MAF Controls the Ability of T Peripheral Helper (Tph) Cells to Help B Cells
Background/Purpose: Pathologic T cell-B cell interactions are hallmark features of many autoimmune diseases. PD-1hi CXCR5- T peripheral helper (Tph) cells are B cell-helper T cells…Abstract Number: 500 • 2019 ACR/ARP Annual Meeting
The Dysregulation of NK Cells and Non-Conventional NK-T and γδ-T Cells in Individuals at Risk of Developing Rheumatoid Arthritis
Background/Purpose: The positivity of antibodies against citrullinated proteins (ACPA) precedes the clinical manifestation and significantly increases the risk of rheumatoid arthritis (RA). EULAR characterised individuals…Abstract Number: 2897 • 2019 ACR/ARP Annual Meeting
Increased CD69+ Tissue-resident Memory T (TRM) Cells and STAT3 Expression in Cutaneous Lupus Erythematosus Patients Recalcitrant to Antimalarials
Background/Purpose: Cutaneous lupus erythematosus (CLE) is an autoimmune disease with various subsets and clinical manifestations. T lymphocytes are the predominant cell type found in lesional…Abstract Number: 588 • 2019 ACR/ARP Annual Meeting
The Gut Enthesis Axis Coming into Focus with the Description of Enriched Entheseal Resident Mucosal Associated Invariant T-cells (MAITs) Capable of IL17A and TNF Production
Background/Purpose: Mucosal associated invariant T-cells (MAITs) are innate-like T lymphocytes that express a semi-invariant TCR repertoire that are activated by microbial ligands or cytokines including…
