    Systemic hypoxia inhibits T cell response by limiting mitobiogenesis via matrix substrate-level phosphorylation arrest

    Amijai Saragovi et al.
    Systemic hypoxia model reveals the detrimental effect of hypoxia on mitochondrial biogenesis in activated T-cells and points at a new approach for improving viral resistance in patients with respiratory diseases.

    Sex-based differences in clearance of chronic Plasmodium falciparum infection

    Jessica Briggs et al.
    Lower malaria prevalence in females does not appear to be due to lower rates of infection but rather due to faster clearance of asymptomatic infections.

    Elongation inhibitors do not prevent the release of puromycylated nascent polypeptide chains from ribosomes

    Benjamin D Hobson et al.
    Although puromycin staining is often used to examine subcellular translation, puromycin-labeled proteins are rapidly released from ribosomes even in the presence of elongation inhibitors, which may confound translation site localization.

    Shear stimulation of FOXC1 and FOXC2 differentially regulates cytoskeletal activity during lymphatic valve maturation

    Pieter R Norden et al.
    Genetic and molecular analyses show that FOXC1 and FOXC2 play a role in controlling lymphatic valve maintenance as key mediators of mechanotransduction to control cytoskeletal organization and RhoA/ROCK signaling.

    Structural basis for ion selectivity in TMEM175 K+ channels

    Janine D Brunner et al.
    Structural and functional analysis of a recently discovered non-canonical potassium channel family reveals a unique selectivity filter that is exposed to permeating ions only in the conductive state.

    In-depth human plasma proteome analysis captures tissue proteins and transfer of protein variants across the placenta

    Maria Pernemalm et al.
    Comprehensive mass spectrometry analysis of human plasma proteome reveals tissue leakage proteins, describes variability between individual plasma proteomes and demonstrates protein transfer across the placenta during pregnancy.

    Oviductal estrogen receptor α signaling prevents protease-mediated embryo death

    Wipawee Winuthayanon et al.
    Cyclic estrogen signaling in oviduct epithelial cells suppresses oviduct luminal protease activity to allow survival and development of preimplantation embryos

    Astrocytes refine cortical connectivity at dendritic spines

    W Christopher Risher et al.
    Spines with multiple excitatory contacts are potential sites for competition between thalamic and cortical axons, which is regulated by the astrocytes through the secreted synaptogenic protein hevin.

    Bacterial colonization stimulates a complex physiological response in the immature human intestinal epithelium

    David R Hill et al.
    Contact with bacteria and subsequent hypoxia promotes functional maturation of the immature gastrointestinal tract.

    Defective STIM-mediated store operated Ca2+ entry in hepatocytes leads to metabolic dysfunction in obesity

    Ana Paula Arruda et al.
    Store operated calcium entry is defective in hepatocytes of obese mice, and restoring this process is sufficient to improve glucose metabolism.
