    COMP-1 promotes competitive advantage of nematode sperm

    Jody M Hansen et al.
    Nematode sperm respond to competitive environments by modulating cellular pathways involved in migration and storage to ensure their access to oocytes.

    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.

    The Toll pathway inhibits tissue growth and regulates cell fitness in an infection-dependent manner

    Federico Germani et al.
    Toll pathway inactivation enhances tissue growth and cell fitness when the environment in which animals develop is not deprived of pathogens.

    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.

    Transient protein accumulation at the center of the T cell antigen-presenting cell interface drives efficient IL-2 secretion

    Danielle J Clark et al.
    A membrane-associated, supramolecular protein complex with dynamically changing components, the central supramolecular activation cluster, regulates the generation of the T cell effector cytokine IL-2 depending on its composition.

    Srsf10 and the minor spliceosome control tissue-specific and dynamic SR protein expression

    Stefan Meinke et al.
    Competition between minor and major splice sites in SRSF10 controls cell type-dependent expression of all SR-proteins and reveals a global impact of the minor spliceosome on major intron splicing.

    Kin cell lysis is a danger signal that activates antibacterial pathways of Pseudomonas aeruginosa

    Michele LeRoux et al.
    The death of bacterial kin cells releases a danger signal that activates a posttranscriptional response in surviving cells, resulting in the rapid elaboration of interbacterial competition factors.

    KRAS-dependent sorting of miRNA to exosomes

    Diana J Cha et al.
    In isogenically matched colorectal cancer (CRC) cell lines, mutant KRAS alters the composition of secreted miRNAs in extracellular vesicles that can then transfer repressive activity to wild type cells.

    Distinct mesoderm migration phenotypes in extra-embryonic and embryonic regions of the early mouse embryo

    Bechara Saykali et al.
    At gastrulation, mesoderm arises as a migratory germ layer that will participate to both foetal and placental development through region-dependant adaptation of cytoskeleton composition, cell shape and migration mode.

    Molecular basis of sidekick-mediated cell-cell adhesion and specificity

    Kerry M Goodman et al.
    Crystal structures of synaptic recognition molecules Sidekick-1 and -2 reveal a single homodimer interaction mode responsible for both cell-cell recognition and cis-clustering, suggesting that competition between cis and trans interactions may be critical to specificity.
