    CDK4/6 Inhibition Promotes Anti-Tumor Immunity through the Induction of T Cell Memory

    Using integrated epigenomic, transcriptomic and proteomic analyses, researchers demonstrated a novel action of CDK4/6 inhibitors in promoting the phenotypic and functional acquisition of immunological T cell memory.

    The Multiple Myeloma Microenvironment Is Defined by an Inflammatory Stromal Cell Landscape

    Investigators generated paired single-cell transcriptomic datasets of tumor cells and the bone marrow immune and stromal microenvironment in multiple myeloma.
    [Nature Immunology]

    Abstract

    Disrupting Tumor Vasculature and Recruitment of aPDL1-Loaded Platelets Control Tumor Metastasis

    The authors utilized the mouse mammary carcinoma cell line 4T1 to develop a strategy that guided an anti-programmed cell death-ligand 1 (aPDL1) antibody to accumulate in metastatic lesions to promote anti-tumor immune responses.

    Platelets Orchestrate the Resolution of Pulmonary Inflammation in Mice by T Reg Cell Repositioning and Macrophage Education

    Researchers demonstrated that platelets were recruited into the lung together with neutrophils during the onset of inflammation and alongside Treg cells during the resolution phase.
    [Journal of Experimental Medicine]

    Abstract

    Neutralization of PD-L2 is Essential for Overcoming Immune Checkpoint Blockade Resistance in Ovarian Cancer

    Investigators found that the immune checkpoint ligand PD-L2 is robustly expressed in patient samples of ovarian cancers and other malignancies exhibiting suboptimal response to immune checkpoint blockade (ICB) but not in cancers that are ICB sensitive.
    [Clinical Cancer Research]

    Abstract

    Galectin-1 Fosters an Immunosuppressive Microenvironment in Colorectal Cancer by Reprogramming CD8+ Regulatory T Cells

    The authors investigated the relevance of galectin-1 in colorectal cancer and explored its modulatory activity within the CD8+ regulatory T cell compartment.

    Abstract

    Pharmacological Inhibition of MDA-9/Syntenin Blocks Breast Cancer Metastasis through Suppression of IL-1β

    Genetic silencing of MDA-9/Syntenin or treatment with a pharmacological inhibitor of the PDZ1 domain, PDZ1i, activated the immune system to kill cancer cells.

    Abstract

    Rational Design of Innate Defense Regulator Peptides as Tumor Vaccine Adjuvants

    The authors develped a screening system for innate defense regulator peptides for composite vaccine adjuvants. 4T1 mammary tumor cells were used to evaluate the antitumor activity of the alum/CpG oligonucleotide/DP7 adjuvant.

    Astragalus membranaceus Polysaccharides Potentiate the Growth-Inhibitory Activity of Immune Checkpoint Inhibitors against Pulmonary Metastatic Melanoma in Mice

    Scientists examined the effect of intranasal administration of A. membranaceus polysaccharides on mucosal immune cell activation and the growth-inhibitory activity against pulmonary metastatic melanoma in mice by combination treatment with immune checkpoint blockade.

    Abstract

    A Bispecific Antibody Agonist of the IL-2 Heterodimeric Receptor Preferentially Promotes In Vivo Expansion of CD8 and NK Cells

    Researchers described a novel bispecific heavy-chain only antibody which bound to and activated signaling through the heterodimeric interleukin-2-2Rβγ receptor complex that was expressed on resting T cells and NK cells.

    Fibroblast-Macrophage Reciprocal Interactions in Health, Fibrosis, and Cancer

    The authors present an integrated view of fibroblast-macrophage interactions that is centered on the CSF1-CSF1R axis and discuss how additional molecular programs linking these cell types can underpin disease onset, progression, and resolution.

    Abstract

    Epigenetic Gene Regulation in Plasma Cells

    Scientists discuss the unique physiology of antibody-secreting cells and how naive B cells undergo epigenetic and genome architectural reorganization to acquire the necessary functions to support antibody production.
    [Immunological Reviews]

    Abstract

    Divalent Cation Signaling in Immune Cells

    Divalent cations of two alkaline earth metals Ca2+ and Mg2+ and the transition metal Zn2+ play vital roles in the immune system, and several immune disorders are associated with disturbances of their function.

    Novo Nordisk Prize for Research on Novel Therapeutic Approaches for Brain Disease

    As wardens and housekeepers, the microglia play a central role in both monitoring and defending the brain and maintaining its normal functions. At the start of his career, German professor Marco Prinz became fascinated by these cells, which were at that time primarily thought to be the brain’s garbage collectors.
