    The transcription factor FOXL2 mobilizes estrogen signaling to maintain the identity of ovarian granulosa cells

    Adrien Georges et al.
    FOXL2 maintenance of ovarian identity is not solely due to a simple direct repression of Sox9 but to the mobilization of estrogen signalling by FOXL2.

    The skin microbiome facilitates adaptive tetrodotoxin production in poisonous newts

    Patric M Vaelli et al.
    Skin-associated bacteria underlie the production of a potent defensive neurotoxin in newts, impacting host physiology, molecular evolution, and predator-prey interactions in a coevolutionary arms race.

    Programmed genome editing of the omega-1 ribonuclease of the blood fluke, Schistosoma mansoni

    Wannaporn Ittiprasert et al.
    Gene knock-out of the omega-1 ribonuclease of Schistosoma mansoni eggs resulted in immunologically impaired phenotype, showcasing the novel application of CRISPR/Cas9 genome editing and utility for functional genomics in schistosomes.

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

    Deeqa Mahamed et al.
    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.

    HIF-1α regulates IL-1β and IL-17 in sarcoidosis

    Jaya Talreja et al.
    Sarcoidosis, a granulomatous disease characterized by macrophage and T-cell activation, is found to be associated with increased HIF-1α transcriptional activity, and modulation of HIF-1α regulates inflammatory immune responses.

    High-resolution mapping of fluoroquinolones in TB rabbit lesions reveals specific distribution in immune cell types

    Landry Blanc et al.
    Penetration of the fluoroquinolones in tuberculosis lesions is heterogeneous even in fully cellular areas, is driven by macrophage content and decreases as the distance from lesion outer rim increases.

    Potentiation of P2RX7 as a host-directed strategy for control of mycobacterial infection

    Molly A Matty et al.
    An in vivo drug screen of FDA-approved compounds in zebrafish identified host-directed therapies against mycobacterial infection, including the drug clemastine, which targets the P2RX7-inflammasome axis to enhance bacterial control.

    A phosphorylation of RIPK3 kinase initiates an intracellular apoptotic pathway that promotes prostaglandin-induced corpus luteum regression

    Dianrong Li et al.
    A phosphorylation of receptor interacting RIPK3 switches its pro-necroptosis function to apoptosis that promotes luteal regression which induced by Prostaglandin F2alpha.

    Sox9 and Sox8 protect the adult testis from male-to-female genetic reprogramming and complete degeneration

    Francisco J Barrionuevo et al.
    The vertebrate testis-determining gene, Sox9, also controls adult testis maintenance in mammals, acting redundantly with its paralog Sox8.

    Identification of novel, clinically correlated autoantigens in the monogenic autoimmune syndrome APS1 by proteome-wide PhIP-Seq

    Sara E Vazquez et al.
    Humans with mutations in the AIRE gene exhibit common autoantibodies targeting ovarian and intestinal antigens, including intestinal dysfunction-associated antibodies to enteroendocrine transcription factor RFX6.
