    Bmal1 integrates mitochondrial metabolism and macrophage activation

    Ryan K Alexander et al.
    Macrophage Bmal1 controls the timing of the glycolytic to oxidative metabolism transition that dictates the extent of Hif-1a activation and the associated inflammatory response.

    Circulating myeloid cells invade the central nervous system to mediate cachexia during pancreatic cancer

    Kevin G Burfeind et al.
    Circulating myeloid cells invade the brain during pancreatic cancer, where they accumulate at a unique central nervous system interface and drive anorexia and muscle catabolism.

    Zebrafish macrophage developmental arrest underlies depletion of microglia and reveals Csf1r-independent metaphocytes

    Laura E Kuil et al.
    Embryonic and definitive macrophages require colony-stimulating factor 1 receptor, whereas non-hematopoietic metaphocytes that resemble macrophages do not, explaining the relative high numbers of putative macrophages in Csf1r-deficient zebrafish.

    A single-cell survey of Drosophila blood

    Sudhir Gopal Tattikota et al.
    Single-cell RNA sequencing of Drosophila hemocytes in blood distinguishes various states within known blood cell types and implicates a novel role for fibroblast growth factor receptor signaling in inter-hemocyte crosstalk.

    The tumor microenvironment as a metabolic barrier to effector T cells and immunotherapy

    Aaron R Lim et al.
    Diverse components of the tumor microenvironment affect T cell metabolism in ways that are crucial to improving immunotherapy.

    The antibiotic bedaquiline activates host macrophage innate immune resistance to bacterial infection

    Alexandre Giraud-Gatineau et al.
    The anti-tuberculosis drug bedaquiline reprograms human macrophages into potent bactericidal phagocytes, which are able to control bacterial infection.

    Endogenous itaconate is not required for particulate matter-induced NRF2 expression or inflammatory response

    Kaitlyn A Sun et al.
    Aconitate decarboxylase 1-derived itaconate reduces mitochondrial respiration via inhibition of succinate dehydrogenase but does not regulate inflammatory response or NRF2 expression in response to particulate matter.

    Tuberculosis-associated IFN-I induces Siglec-1 on tunneling nanotubes and favors HIV-1 spread in macrophages

    Maeva Dupont et al.
    Type-I interferon enriched microenvironment generated by Mycobacterium tuberculosis induces the Siglec-1 receptor expression in human macrophages, including on tunneling nanotubes, and contributes to the exacerbation of cell-to-cell transfer of HIV-1.

    LRRK2 maintains mitochondrial homeostasis and regulates innate immune responses to Mycobacterium tuberculosis

    Chi G Weindel et al.
    Long studied in the context of the central nervous system, LRRK2 also functions in peripheral immunity by maintaining mitochondrial homeostasis in macrophages to regulate the type I interferon response.
