    Ambient Oxygen Levels Regulate Intestinal Dysbiosis and GVHD Severity After Allogeneic Stem Cell Transplantation

    The authors showed in multiple specific pathogen-free, gnotobiotic, and germ-free murine models of gastrointestinal (GI) GVHD that the initiation of the intestinal damage by the pathogenic T cells altered ambient oxygen levels in the GI tract and caused dysbiosis.

    Abstract

    Genetic and Pharmacologic Inhibition of ALDH1A3 as a Treatment of β-Cell Failure

    Researchers investigated the fate of ALDH1A3-positive β-cells during pair-feeding by lineage-tracing, somatically ablated ALDH1A3 in diabetic β-cells, and used a novel selective ALDH1A3 inhibitor to treat diabetes.

    In-Situ Cryo-Immune Engineering of Tumor Microenvironment with Cold-Responsive Nanotechnology for Cancer Immunotherapy

    After the in-situ cryo-immune engineering treatment, the ratio of the CD8+ cytotoxic T cells to the immunosuppressive regulatory T cells was increased by more than 100 times, in not only the primary tumors with cryosurgery, but also distant tumors without freezing.

    Identification of Procathepsin L (pCTS-L)–Neutralizing Monoclonal Antibodies to Treat Potentially Lethal Sepsis

    The authors reported that the expression and secretion of procathepsin-L was induced by serum amyloid A in innate immune cells, contributing to its late and systemic accumulation in experimental and clinical sepsis.

    Crosstalk between ILC2s and Th2 Cells Varies Among Mouse Models

    Scientists reported that IL-33-mediated ILC2 activation promoted the Th2 cell response to papain; however, the Th2 cell response to ovalbumin/alum immunization was thymic stromal lymphopoietin dependent, but independent of ILC2s.

    Mechanisms Driving the Immunoregulatory Function of Cancer Cells

    The authors discuss how cancer cell-intrinsic features, including (epi)genetic aberrations, signaling pathway deregulation and altered metabolism, play a key role in orchestrating the composition and functional state of the immune landscape, and influence the therapeutic benefit of immunomodulatory strategies.
