    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.

    Quantifying the contribution of Plasmodium falciparum malaria to febrile illness amongst African children

    Ursula Dalrymple et al.
    Fevers amongst African children are often assumed to be caused by a malaria infection, but here it is estimated that the majority of fevers amongst African children, including those with a patent malaria infection, are due to infections with diseases other than malaria.

    Drosophila Synaptotagmin 7 negatively regulates synaptic vesicle release and replenishment in a dosage-dependent manner

    Zhuo Guan et al.
    Drosophila synaptotagmin 7 functions to restrict SV availability and release, but does not act as the Ca2+ sensor mediating the asynchronous release and facilitation remaining in synaptotagmin 1 mutants.

    Mitochondrial flashes regulate ATP homeostasis in the heart

    Xianhua Wang et al.
    Mitochondrial flashes counteract the imbalance of ATP supply-and-demand and constitute an auto-regulator of ATP homeostasis in the heart.

    The carboxyl-terminal sequence of bim enables bax activation and killing of unprimed cells

    Xiaoke Chi et al.
    The C-terminal membrane binding domain of Bim is shown to interact with and activate Bim enabling it to kill cells not dependent on anti-apoptotic proteins for survival.

    Structural basis of αE-catenin–F-actin catch bond behavior

    Xiao-Ping Xu et al.
    A molecular mechanism for force-dependent binding of the cell adhesion proteins αE-catenin and vinculin to actin is derived from the structure of the αE-catenin actin-binding domain bound to F-actin.

    Critical roles of mTOR Complex 1 and 2 for T follicular helper cell differentiation and germinal center responses

    Jialong Yang et al.
    Genetic ablation of Raptor and Rictor in mice revealed critical roles of mTORC1 and mTORC2 in T follicular helper cell differentiation and germinal center responses.

    Regulation of mitochondria-dynactin interaction and mitochondrial retrograde transport in axons

    Catherine M Drerup et al.
    Actr10, a dynactin pointed end protein, is essential for mitochondrial interaction with the dynein-dynactin retrograde motor and subsequent transport.

    More homogeneous capillary flow and oxygenation in deeper cortical layers correlate with increased oxygen extraction

    Baoqiang Li et al.
    Resting-state capillary blood flow and oxygenation are more homogeneous in the deeper cortical layers, underpinning an important mechanism by which the microvascular network adapts to an increased local oxidative metabolism.

    Molecular basis for the adaptive evolution of environment-sensing by H-NS proteins

    Xiaochuan Zhao et al.
    Combining in silico and experimental approaches to identify and understand the residue changes in the H-NS protein that allowed bacteria to adapt environment-sensing to different habitats.
