    ZBP1-MLKL Necroptotic Signaling Potentiates Radiation-Induced Antitumor Immunity via Intratumoral STING Pathway Activation

    Scientists demonstrated that the fibrin-based gel delivery of CAR-T cells within the surgical cavity enables superior antitumor activity compared to CAR-T cells directly inoculated into the tumor resection cavity.

    Tubular Lysosomes Harbor Active Ion Gradients and Poise Macrophages for Phagocytosis

    Investigators described a DNA-based assembly that tubulated lysosomes in macrophages without activating them. Proteolytic activity maps at single-lysosome resolution revealed that tubular lysosomes were less degradative and showed proximal to distal luminal pH and Ca2+ gradients.

    Attenuation of Apoptotic Cell Detection Triggers Thymic Regeneration after Damage

    The authors demonstrated a trigger of thymic regeneration, centered on detecting the loss of dying thymocytes that were abundant during steady-state T cell development.

    Niraparib Exhibits a Synergistic Anti-Tumor Effect with PD-L1 Blockade by Inducing an Immune Response in Ovarian Cancer

    Programmed death ligand 1 (PD-L1) expression in human ovarian cancer cells after PARP inhibitors treatment was examined by western blotting and flow cytometry.

    Irbesartan, an Angiotensin II Type 1 Receptor Blocker, Inhibits Colitis-Associated Tumorigenesis by Blocking the MCP-1/CCR2 Pathway

    Irbesartan suppressedmonocyte chemoattractant protein-1 (MCP-1) production and the accumulation of Ly6C+CCR2+ monocytes and fibrocytes in the inflamed colon, downregulated the expression of type 1 collagen and matrix metalloproteinase 9 and inhibited the development of intestinal fibrosis and tumors.

    Genome-Wide Associations for Immune Traits in Two Maternal Pig Lines

    The objective of this study was to identify genomic regions with a biological relevance for the immunocompetence of piglets. Genome-wide Association Studies in 535 Landrace and 461 Large White piglets were performed, investigating 20 immune relevant traits.

    Abstract

    Biomaterial-Enabled Induction of Pancreatic-Specific Regulatory T Cells through Distinct Signal Transduction Pathways

    Scientists used poly (lactic-co-glycolide) to co-encapsulate type 1 diabetes-relevant antigen and three distinct TREG-inducing molecules – rapamycin, all-trans retinoic acid, and butyrate – that targeted the mechanistic target of Rapa, the retinoid pathway, and histone deacetylase inhibition, respectively.

    Intrauterine Administration of Peripheral Blood Mononuclear Cells (PBMCs) Improves Embryo Implantation in Mice by Regulating Local Treg/Th17 Cell Balance

    Investigators determined the effect of intrauterine administration of mouse PBMCs prior to embryo implantation on endometrial receptivity and embryo implantation, and examined the underlying mechanism of Treg/Th17 cell balance following intrauterine administration of PBMCs.
