    Immune Response after Pig-to-Human Kidney Xenotransplantation: A Multimodal Phenotyping Study

    Scientists did a complete phenotyping of two pig kidney xenografts transplanted to decedent humans, using a multimodal strategy combining morphological evaluation, immunophenotyping, gene expression profiling, and whole-transcriptome digital spatial profiling and cell deconvolution.

    Abstract

    A Pan-Cancer Single-Cell Panorama of Human Natural Killer Cells

    To depict NK cells’ phenotypic and functional diversities in the tumor microenvironment, researchers performed integrative single-cell RNA sequencing analyses on NK cells from 716 patients with cancer, covering 24 cancer types.

    TIGIT Can Inhibit T Cell Activation via Ligation-Induced Nanoclusters, Independent of CD226 Co-Stimulation

    By analysing lymphocytes from matched human tumor and peripheral blood samples, investigators showed that TIGIT and CD226 co-expression was rare on tumor-infiltrating lymphocytes.

    Abstract

    IFNɣ but Not IFNα Increases Recognition of Insulin Defective Ribosomal Product-Derived Antigen to Amplify Islet Autoimmunity

    The authors studied the role of early innate cytokines (IFNα) and late immune adaptive events (IFNɣ) in insulin defective ribosomal products-derived peptide presentation to diabetogenic CD8+ T cells.

    Epigenetic Signature of Human Immune Aging in the GESTALT Study

    Investigators identified age-associated DNA methylation sites in six purified blood borne immune cell types, naïve B, naïve CD4+ and CD8+ T cells, granulocytes, monocytes and NK cells, collected from healthy individuals interspersed over a wide age range.
