Mitochondrial dysfunction drives natural killer cell dysfunction in systemic lupus erythematosus
Background/Purpose: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by immune dysregulation and widespread inflammation. Natural killer (NK) cells, essential for immune surveillance,…Abstract Number: 1876 • ACR Convergence 2025
Targeting the NK cell checkpoint NKG2A promotes lung fibrosis resolution by enhancing immune clearance of senescent myofibroblasts
Background/Purpose: A key event driving pulmonary fibrosis in interstitial lung disease (ILD) is the accumulation of pathologic senescent myofibroblasts, thought to be promoted by insufficient…Abstract Number: 1824 • ACR Convergence 2025
Tissue-Resident Natural Killer Cells May Drive Monocyte Differentiation And Macrophage Accumulation In The Inflamed Joints Of Pediatric Juvenile Idiopathic Arthritis Patients
Background/Purpose: Natural Killer (NK) cells are the most abundant innate lymphoid cells, accounting for 10–40% of total lymphocytes in peripheral blood. They adapt to diverse…Abstract Number: 1145 • ACR Convergence 2025
Numerically Reduced but MSU Crystal-Activated NK Cells Promote Osteoclastogenesis in Gout
Background/Purpose: Gout is an inflammatory arthritis characterized by acute attacks, tophi formation, and bone destruction triggered by inflammatory responses to monosodium urate (MSU) crystals. Natural…Abstract Number: 1094 • ACR Convergence 2025
Changes in NK cells and TH cell phenotype in Rheumatoid Arthritis patients treated with janus kinase inhibitors: implications for adverse effects
Background/Purpose: Janus kinase inhibitors (JAKi) are effective in rheumatoid arthritis (RA); however, concerns regarding safety, particularly the risk of infections and malignancies, have been raised.…Abstract Number: 0933 • ACR Convergence 2025
Spatial Transcriptomics Reveal Altered Immune Dynamics Regulating Placental Development In a Humanized-TLR8 Mouse Model of Spontaneous Anti-Phospholipid Antibody Induced Pregnancy Loss
Background/Purpose: TLR8 has been implicated in adverse outcomes of human pregnancy. We previously reported a mouse model of spontaneous aPL-induced pregnancy loss in Sle1 mice…Abstract Number: 0932 • ACR Convergence 2025
Compartment-specific NK-cell phenotypes reveal distinct maturation and activation states in inflammatory arthritis
Background/Purpose: Synovial natural killer (NK) cells contribute to inflammation in arthritis by secreting cytokines and modulating synovial fibroblast activation. The aim of this study is…Abstract Number: 0039 • ACR Convergence 2025
Hemophagocytic Lymphohistiocytosis Gene Variants in Severe COVID-19 Cytokine Storm Syndrome
Background/Purpose: Severe COVID-19 infection resulting in hospitalization shares features with frequently fatal cytokine storm syndromes (CSS), such as hemophagocytic lymphohistiocytosis (HLH) and macrophage activation syndrome…Abstract Number: 0014 • ACR Convergence 2025
NKX019, an allogeneic off-the-shelf CD19 targeting CAR-NK cell therapy, induces deep CD19+ B cell depletion in hematological malignancy and models of autoimmune disease
Background/Purpose: Autologous CAR T-cell therapies have remarkable clinical activity in autoimmune disease (AD) via B-cell targeting, with many patients achieving durable, drug-free remission. However, safety…Abstract Number: L17 • ACR Convergence 2024
Allogenic CD19 CAR NK Cells Therapy in Refractory Systemic Lupus Erythematosus: An Open-label, Single Arm, Prospective and Interventional Clinical Trial
Background/Purpose: Treatment of systemic lupus erythematosus (SLE) typically necessitates long-term immunosuppression with hormones, immunosuppressants and biologics. CD19-targeting chimeric antigen receptor (CAR) T cells have shown excellent…Abstract Number: 1763 • ACR Convergence 2024
