    Nerfin-1 represses transcriptional output of Hippo signaling in cell competition

    Pengfei Guo et al.
    The zinc finger protein Nerfin-1 represses the transcriptional output of Hippo signaling in cell competition by binding to the TEA DNA-binding domain of Scalloped.

    Similar GABAA receptor subunit composition in somatic and axon initial segment synapses of hippocampal pyramidal cells

    Katalin Kerti-Szigeti, Zoltan Nusser
    All perisomatic GABAergic synpases on hippocampal pyramidal cells have a similar GABAA receptor subunit composition.

    Stochastic homeostasis in human airway epithelium is achieved by neutral competition of basal cell progenitors

    Vitor H Teixeira et al.
    Cell replenishment within the airways is governed by the random division of a population of basal progenitor cells, in a process that is accelerated in smokers.

    Ephrin-B3 controls excitatory synapse density through cell-cell competition for EphBs

    Nathan T Henderson et al.
    Competition between neurons for postsynaptic ephrin-B3 controls distribution of a limited pool of synapses and defines a novel trans-synaptic mechanism enabling neurons to set the number of synapses they receive.

    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.

    Composition and structure of synaptic ectosomes exporting antigen receptor linked to functional CD40 ligand from helper T cells

    David G Saliba et al.
    TCR and CD40L microclusters are linked in synaptic ectosomes (extracellular vesicles) and released in the immunological synapse by helper T cells and induce dendritic cell maturation and cytokine production.

    Bacteria: Exploring new horizons

    Vineetha M Zacharia, Matthew F Traxler
    Streptomyces bacteria employ a newly-discovered cell type, the "explorer" cell, to rapidly colonize new areas in the face of competition.

    Adult-born neurons modify excitatory synaptic transmission to existing neurons

    Elena W Adlaf et al.
    The formation of new neurons in the adult dentate gyrus causes a proportion of cortical neurons to transfer their existing connections to the newborn cells.
