    CXCR6 Positions Cytotoxic T Cells to Receive Critical Survival Signals in the Tumor Microenvironment

    The authors showed that the conversion of stem-like into effector-like cytotoxic T lymphocyte involved a major chemotactic reprogramming that included the upregulation of chemokine receptor CXCR6.

    Dual Targeting of CTLA-4 and CD47 on Treg Cells Promotes Immunity against Solid Tumors

    Scientists found that anti–cytotoxic T lymphocyte–associated protein 4 (CTLA-4)×SIRPα preferentially depleted ICOShigh immunosuppressive Treg cells in the tumor microenvironment and enhanced immunity against solid tumors, including MC38 and CT26 murine colon cancers.

    Metabolic and Transcriptomic Profiles of Glioblastoma Invasion Revealed by Comparisons between Patients and Corresponding Orthotopic Xenografts in Mice

    Researchers reported biological features of invasive growth accompanying tumor progression and invasion based on associated metabolic and transcriptomic changes observed in patient derived orthotopic xenografts in the mouse and the corresponding patients’ tumors.

    Molecular Control of Cell Density-Mediated Exit to Quiescence

    Investigators showed that the variable memory of local cell density experienced by a mother cell controls the levels of the cyclin-dependent kinase activator cyclin D1 and inhibitor p27 in newborn daughters, which directed cells to proliferation or quiescence.

    Degradable RGD-Functionalized 3D-Printed Scaffold Promotes Osteogenesis

    The authors proposed to infuse a degradable RGD-functionalized alginate matrix with osteoid-like stiffness, as an artificial ECM, to a rigid 3D-printed hydroxyapatite scaffold for maxillofacial regeneration.

    Abstract

    Dietary Salt Exacerbates Intestinal Fibrosis in Chronic TNBS Colitis via Fibroblasts Activation

    Investigators analyzed the role of dietary salt in TNBS chronic colitis induced in rat, an intestinal fibrosis model, and in human colon fibroblast cells and showed that high-salt diet exacerbated undernutrition and promoted ECM-associated proteins in fibroblasts.
