    Club cells form lung adenocarcinomas and maintain the alveoli of adult mice

    Magda Spella, Ioannis Lilis ... Georgios T Stathopoulos
    Airway cells are required for the maintenance of the adult mouse lung and for carcinogen-induced lung adenocarcinoma development, and are thus marked therapeutic targets.

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

    Kaitlyn A Sun, Yan Li ... Gökhan M Mutlu
    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.

    Systems level identification of a matrisome-associated macrophage polarisation state in multi-organ fibrosis

    John F Ouyang, Kunal Mishra ... Jacques Behmoaras
    A meta-analysis of single-cell data reveals an advanced and conserved polarisation state of SPP1+ macrophages in multiple human fibrotic tissues.

    Creating an atlas of the bone microenvironment during oral inflammatory-related bone disease using single-cell profiling

    Yi Fan, Ping Lyu ... Chenchen Zhou
    Single-cell sequencing of the alveolar bone marrow of apical periodontitis reveals the cellular and molecular composition of the microenvironment and highlights an osteogenic potential within mesenchymal stem cells of inflammatory-related bone diseases.

    Diverse homeostatic and immunomodulatory roles of immune cells in the developing mouse lung at single cell resolution

    Racquel Domingo-Gonzalez, Fabio Zanini ... Cristina M Alvira
    Single cell transcriptomics reveal a complex orchestration of lung immune cells during the transition from fetal to air-breathing life to fill context-specific functions in tissue remodeling, angiogenesis, and immunity.

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

    Maeva Dupont, Shanti Souriant ... Geanncarlo Lugo-Villarino
    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.

    Intracellular growth of Mycobacterium tuberculosis after macrophage cell death leads to serial killing of host cells

    Deeqa Mahamed, Mikael Boulle ... Alex Sigal
    The rapid killing of macrophages by Mycobacterium tuberculosis aggregates, and the subsequent proliferation of the bacteria inside the dead cell, leads to a cell death cascade and explains the coupling of necrosis and pathogen growth observed in active disease.

    Diverse fates of uracilated HIV-1 DNA during infection of myeloid lineage cells

    Erik C Hansen, Monica Ransom ... James T Stivers
    Uracil/adenine base pairs in HIV-1 DNA are attacked by the uracil base excision repair machinery in macrophages, which leads to HIV restriction and viral genome diversification by transcription-associated mutagenesis.

    Bronchus-associated macrophages efficiently capture and present soluble inhaled antigens and are capable of local Th2 cell activation

    Xin-Zi Tang, Lieselotte S M Kreuk ... Christopher D C Allen
    Lung interstitial macrophages are strategically positioned underneath the bronchial airway epithelium and enriched at airway bifurcations for immunosurveillance of the conducting airway lumen and the initiation of adaptive immune responses.

    Telocytes regulate macrophages in periodontal disease

    Jing Zhao, Anahid A Birjandi ... Paul Sharpe
    A poorly understood cell type, the telocyte, is shown to regulate macrophages.
