    Somatosensory neurons integrate the geometry of skin deformation and mechanotransduction channels to shape touch sensing

    Alessandro Sanzeni et al.
    Nonlinear elasticity of skin tissues and somatosensory neural responses are combined to predict and test C. elegans processing of touch stimuli and modifications due to changes in the body mechanics.

    Formin-2 drives polymerisation of actin filaments enabling segregation of apicoplasts and cytokinesis in Plasmodium falciparum

    Johannes Felix Stortz et al.
    Formin-2 controls spatiotemporal polymerisation of actin filaments, a common mechanism used by apicomplexans for effective segregation of essential chloroplast-like organelles called apicoplasts, and additionally for daughter formation in Plasmodium falciparum.

    Lmx1b is required at multiple stages to build expansive serotonergic axon architectures

    Lauren J Donovan et al.
    A continuously expressed LIM HD factor, Lmx1b, acts at successive stages to orchestrate the progressive morphological maturation of a long-range profusely arborized neuromodulatory axonal projection pathway.

    A two-step mechanism for the inactivation of microtubule organizing center function at the centrosome

    Jérémy Magescas et al.
    The microtubule organizing potential of the centrosome is inactivated in a stepwise process through phosphatase activity and mechanical disruption to remove an aging matrix of proteins.

    Type-I myosins promote actin polymerization to drive membrane bending in endocytosis

    Hetty E Manenschijn et al.
    Monomeric myosins can stimulate growth of actin filaments under load.

    Combinations of Spok genes create multiple meiotic drivers in Podospora

    Aaron A Vogan et al.
    Members of a single gene family determine the genomic basis of multiple coexisting meiotic drive elements in natural populations of Podospora.

    Agrin-Lrp4-Ror2 signaling regulates adult hippocampal neurogenesis in mice

    Hongsheng Zhang et al.
    Enriched environment stimulates neuron generation in the hippocampus by a novel pathway involving Agrin, Lrp4, and Ror2.

    The transcription factor Hey and nuclear lamins specify and maintain cell identity

    Naama Flint Brodsly et al.
    Hey together with LaminC continuously supervise nuclear organisation and differentiated enterocyte identity, a regulation that is lost upon ageing, resulting in loss of gut homeostasis.

    A composition-dependent molecular clutch between T cell signaling condensates and actin

    Jonathon A Ditlev et al.
    Compositional changes alter actin binding by phase separated T cell signaling clusters, enabling cluster movement by distinct actin networks.

    Defective AMH signaling disrupts GnRH neuron development and function and contributes to hypogonadotropic hypogonadism

    Samuel Andrew Malone et al.
    Mouse in vivo and in vitro analysis and human genetic screening highlight the role of anti-Müllerian hormone (AMH) signaling in GnRH neuronal development and function, and identify mutations in AMH and AMHR2 in CHH patients.
