Inhibition of host NOX1 blocks tumor growth and enhances checkpoint inhibitor–based immunotherapyBlocking NOX1 with the novel small molecule inhibitor GKT771 inhibits tumor growth in mice by targeting tumor lymph/angiogenesis and promoting antitumor immune cells recruitment. GKT771 emerges as a novel and promising anticancer drug worth translating into the clinics.
Assembly mechanisms of the bacterial cytoskeletal protein FilPFilP is a coiled-coil protein that self-assembles into striated filaments and meshwork that shares structural and biochemical characteristics with metazoan intermediate filaments.
Tamoxifen blocks retrograde trafficking of Shiga toxin 1 and 2 and protects against lethal toxicosisThis study reports an unexpected role of late endosome–lysosome fusion in early endosome-to-Golgi trafficking of Shiga toxins and identifies tamoxifen to be a potent inhibitor of Shiga toxicosis.
Fibro-adipogenic progenitors of dystrophic mice are insensitive to NOTCH regulation of adipogenesisThe NOTCH pathway, in concert with TNFa, restrains adipogenesis of muscle fibro-adipogenic progenitors (FAPs). Dystrophin-deficient FAPs are less sensitive to NOTCH anti-adipogenic signals, thus explaining why fat infiltrations are solely observed in the muscles of dystrophic individuals.
An unusual and vital protein with guanylate cyclase and P4-ATPase domains in a pathogenic protistToxoplasma gondii harbors an alveolate-specific guanylate cyclase linked to P-type ATPase motifs, which is an essential actuator of cGMP-dependent gliding motility, egress, and invasion during acute infection.
Expression of a constitutively active human STING mutant in hematopoietic cells produces an Ifnar1-dependent vasculopathy in miceTransgenic expression of a mutant hSTING cDNA under the control of the Vav1 gene promoter leads to a vasculopathy similar to that of the interferonopathy, STING-associated vasculopathy of infancy.
Evidence for vesicle-mediated antigen export by the human pathogen Babesia microtiThe human pathogen Babesia microti undergoes unique morphogenesis during its development within human and mouse red blood cells and uses a novel vesicle-based system for export of antigens into the host cell and environment.
CRISPR-induced double-strand breaks trigger recombination between homologous chromosome armsCRISPR–Cas9 enables recombination between homologous chromosome arms at predefined sites and also underscores the need for caution when applying CRISPR technologies in translational medicine.
The WT1–BASP1 complex is required to maintain the differentiated state of taste receptor cellsThe WT1/BASP1 complex is important to maintain taste receptor cells in their terminally differentiated state.
Molecular characterization of Chlamydomonas reinhardtii telomeres and telomerase mutantsThis study characterizes the sequence, end structure, and length distribution of Chlamydomonas reinhardtii telomeres and shows that telomerase mutants are defective in telomere maintenance.
