    Anti-TIGIT Antibody Improves PD-L1 Blockade through Myeloid and Treg Cells

    Investigators found that a high baseline of intratumoural macrophages and regulatory T cells was associated with better outcomes in patients treated with atezolizumab plus tiragolumab but not with atezolizumab alone.

    Iron Dysregulation and Inflammatory Stress Erythropoiesis Associates with Long-Term Outcome of COVID-19

    Researchers assessed 214 individuals infected with SARS-CoV-2, with varying disease severity, for one year from COVID-19 symptom onset to determine the early correlates of post-acute sequelae.

    A Functional Identification Platform Reveals Frequent, Spontaneous Neoantigen-Specific T Cell Responses in Patients with Cancer

    Scientists developed a platform that combined bioinformatic analysis of tumor exomes and transcriptional data with functional testing of autologous peripheral blood mononuclear cells to simultaneously identify and validate neoantigens recognized by naturally primed CD4+ and CD8+ T cell responses.

    Rare SH2B3 Coding Variants in Lupus Patients Impair B Cell Tolerance and Predispose to Autoimmunity

    The authors showed that unlike the variant found exclusively in healthy controls, SH2B3 rare variants found in lupus patients were predominantly hypomorphic alleles, failing to suppress IFNGR signaling via JAK2-STAT1.

    Abstract

    An Immunosuppressive Vascular Niche Drives Macrophage Polarization and Immunotherapy Resistance in Glioblastoma

    Investigators identified a distinct mesenchymal-like population of endothelial cells that formed an immunosuppressive vascular niche in glioblastoma.

    Chronic Stress Exacerbates the Immunosuppressive Microenvironment and Progression of Gliomas by Reducing Secretion of CCL3

    The authors revealed that chronic stress inhibited the recruitment of tumor-associated macrophages and other immune cells, and decreased the level of proinflammatory cytokines in gliomas, leading to an immunosuppressive microenvironment and glioma progression.

    Abstract

    Retinoic Acid-Loaded Liposomes Induce Human Mucosal CD103+ Dendritic Cells That Inhibit Th17 Cells and Drive Regulatory T Cell Development In Vitro

    Scientists investigated the effects of retinoic acid-loaded liposomes on human dendritic cell (DC) phenotype and function, including DC-driven T-cell development, both during the generation of monocyte-derived DCs (moDCs) as well as by priming immature moDCs.

    Combination of IL-33 with PD-1 Blockade Augment mILC2s-Mediated Anti-Tumor Immunity

    The proportion of group 2 innate lymphoid cells (ILC2s) originating from various tissue sources were quantified through flow cytometry, along with the determination of CD4+ T cell and CD8+ T cell percentages.

    Th17/1 and Ex-Th17 Cells Are Detected in Patients with Polyarticular Juvenile Arthritis and Increase following Treatment

    Blood from 17 patients with polyarticular juvenile idiopathic arthritis was collected at initial diagnosis and again if remission was achieved. Pediatric healthy controls were also collected.
