A new twist on superantigen-activated autoimmune disease.
J Clin Invest

Division of Rheumatology, Center of Excellence for Intestinal and Immunology Research, University of Alberta, Edmonton, Alberta, Canada.
Superantigen-induced (Sag-induced) autoimmunity has been proposed as a mechanism for many human disorders, without a clear understanding of the potential triggers. In this issue of the JCI, McCarthy and colleagues used the SKG mouse model of rheumatoid arthritis to characterize the role of Sag activity in inflammatory arthritis by profiling arthritogenic naive CD4+ T cells. Within the diseased joints, they found a marked enrichment of T cell receptor-variable β (TCR-Vβ) subsets that were reactive to the endogenously encoded mouse mammary tumor virus (MMTV) Sag.

Department of Immunology and inflammation, Imperial College London, UK.
Background: Takayasu arteritis (TAK) and giant cell arteritis (GCA), the most common forms of large-vessel vasculitis (LVV), can result in serious morbidity. Understanding the molecular basis of LVV should aid in developing better biomarkers and treatments.
Methods: Plasma proteomic profiling of 184 proteins was performed in two cohorts.
Effects of on disease activity, T lymphocytes and inflammatory cytokine profiles in pediatric systemic lupus erythematosus: A randomized controlled trial.

Department of Pediatrics, Faculty of Medicine, Universitas Brawijaya, Malang, Indonesia.
Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with diverse manifestations, requiring long-term treatment that can have side effects, particularly in pediatric patients. has shown potential for improving SLE symptoms due to its anti-inflammatory and immunomodulatory effects. The aim of this study was to investigate the immunomodulatory effect of oil (NSO) on disease activity, T lymphocyte activity and inflammatory cytokine profiles in pediatric SLE patients.

Recently, a strategy involving the engineering of chemokine receptors on immune cells was developed to optimize adoptive cell therapy (ACT) for solid tumors. Given the variability in chemokine secretion among different tumor types, identifying and modulating the appropriate chemokine receptors is crucial. In this study, we utilized extensive RNA sequencing data from both tumor tissues from The Cancer Genome Atlas and normal tissues from Genotype-Tissue Expression to investigate the expression profiles of chemokines.
