    MicroRNA-206 Promotes the Recruitment of CD8+ T Cells by Driving M1 Polarisation of Kupffer Cells

    FVB/NJ mice were hydrodynamically injected with AKT/Ras and Sleeping Beauty transposon to induce hepatocellular carcinoma. Mini-circle and Sleeping Beauty were used to overexpress microRNA-206 in Kupffer cells of mice.

    Abstract

    Brain Inflammation Triggers Macrophage Invasion across the Blood-Brain Barrier in Drosophila during Pupal Stages

    Researchers showed that the immune deficiency pathway, but not the Toll pathway, was responsible for attraction and invasion of hemolymph-borne macrophages across the blood-brain barrier during pupal stages.

    Optineurin Modulates the Maturation of Dendritic Cells to Regulate Autoimmunity through JAK2-STAT3 Signaling

    Investigators showed that optineurin was upregulated in human and mouse dendritic cell (DC) maturation, and that deletion of Optn in mice via CD11c-Cre attenuated DC maturation and impaired the priming of CD4+ T cells, thus ameliorating autoimmune symptoms such as experimental autoimmune encephalomyelitis.

    Abstract

    Smart Exosomes with Lymph Node Homing and Immune Amplifying Capacities for Enhanced Immunotherapy of Metastatic Breast Cancer

    A type of smart exosomes was developed, in which the exosome surface was functionally engineered with CD62L and OX40L by forced expression of the genes in the donor cells.
