    Abstract

    Extracting Immunological and Clinical Heterogeneity across Autoimmune Rheumatic Diseases by Cohort-Wide Immunophenotyping

    Investigators conducted large-scale and cohort-wide immunophenotyping of 46 peripheral immune cells using Human Immunology Protocol of comprehensive eight-color flow cytometric analyses.

    Abstract

    Identification and Characterization of CD8+CD27+CXCR3 T Cell Dysregulation and Progression-Associated Biomarkers in Systemic Lupus Erythematosus

    The comprehensive immune cell dysregulation in total 263 clinical peripheral blood samples composed of active systemic lupus erythematosus (SLE), remission SLE, and healthy controls was investigated via mass cytometry, flow cytometry, and single-cell RNA sequencing.

    Human Interleukin-12α and EBI3 Are Cytokines with Anti-Inflammatory Functions

    Scientists demonstrated that IL-12α and EBI3 were stable proteins in isolation that acted as anti-inflammatory molecules. Both reduced secretion of proinflammatory cytokines and induced the development of regulatory T cells.

    Human IL-17A Protein Production Is Controlled through a PIP5K1α-Dependent Translational Checkpoint

    Researchers found that phosphatidylinositol 4,5-bisphosphate was enriched in the nuclei of human TH17 cells, which depended on the kinase PIP5K1α, and that inhibition of PIP5K1α impaired IL-17A production.

    Abstract

    Human HLA-DR+CD27+ Regulatory T Cells Show Enhanced Antigen-Specific Suppressive Function

    Expansion of human Tregs in the presence of porcine PBMC allowed the selection of a distinct Treg subset, co-expressing the activation/memory surface markers HLA-DR and CD27 with enhanced proportion of FOXP3+Helios+ Tregs.
