    Metformin alleviates stress-induced cellular senescence of aging human adipose stromal cells and the ensuing adipocyte dysfunction

    Laura Le Pelletier et al.
    Aging is associated with stress-induced senescence of adipose stromal cells, leading to impaired adipogenesis, oxidative stress, mitochondrial dysfunction, and insulin resistance, all being alleviated by metformin treatment of adipose stromal cells.

    Mosquito infection by gametocytes from cultures exposed to dihydroartemisinin (DHA) from Figure 2, Portugaliza et al.

    Malaria: A Collection of Articles

    Edited by Olivier Silvie et al.
    eLife has recently published a wide range of papers on malaria, covering a diversity of themes including parasite biology, epidemiology, immunology, drugs and vaccines.

    Memory recall involves a transient break in excitatory-inhibitory balance

    Renée S Koolschijn et al.
    Hippocampal activity during memory recall predicts a transient increase in the ratio between neocortical glutamate and GABA, thereby allowing otherwise dormant memories to be released.

    The transcription factor Xrp1 is required for PERK-mediated antioxidant gene induction in Drosophila

    Brian Brown et al.
    The transcription factor Xrp1 mediates a previously unrecognized branch of stress-response signaling, specifically as a downstream effector of eIF2alpha kinases.

    The LRRK2 G2019S mutation alters astrocyte-to-neuron communication via extracellular vesicles and induces neuron atrophy in a human iPSC-derived model of Parkinson’s disease

    Aurelie de Rus Jacquet et al.
    Extracellular vesicles are proposed as novel, non-cell-autonomous mediators of neuronal atrophy in Parkinson's disease.

    MACF1 controls skeletal muscle function through the microtubule-dependent localization of extra-synaptic myonuclei and mitochondria biogenesis

    Alireza Ghasemizadeh et al.
    Maintenance of peripheral myonuclei patterning in skeletal myofibers is dependent on the regulation of microtubules dynamic and nuclei motion and is essential for proper neuromuscular junction integrity and mitochondria homeostasis.

    Lipid droplets and ferritin heavy chain: a devilish liaison in human cancer cell radioresistance

    Luca Tirinato et al.
    Lipid Droplet accumulation is a fingerprint shared by different human cancer radioresistant cells and their biogenesis strongly depend on FTH1 presence.

    Structural characterization of NrnC identifies unifying features of dinucleotidases

    Justin D Lormand et al.
    Dinucleotidases, specialized enzymes that catalyze the final step in RNA degradation, have evolved independently and repeatedly to fulfill essential roles in cell growth.
