    The structure and dynamics of secretory component and its interactions with polymeric immunoglobulins

    Beth M Stadtmueller et al.
    The ectodomain of the human polymeric Ig receptor maintains a closed triangular shape that binds and excludes bacteria in mucosa, or opens to bind and transport polymeric Ig ligands across epithelial cells.

    Mycobacterium tuberculosis exploits host ATM kinase for survival advantage through SecA2 secretome

    Savita Lochab et al.
    Mycobacterium tuberculosis (Mtb), effectors secreted through SecA2 pathway cause double strand breaks (DSBs) in the host DNA, which in turn activates ATM kinase to gain survival advantages, through Akt.

    Ovulation in Drosophila is controlled by secretory cells of the female reproductive tract

    Jianjun Sun, Allan C Spradling
    Secretory cells in the fruit fly reproductive tract produce secretions that control ovulation through a conserved mechanism that could provide insights into ovarian cancer.

    Exophilin-8 assembles secretory granules for exocytosis in the actin cortex via interaction with RIM-BP2 and myosin-VIIa

    Fushun Fan et al.
    Analyses of knockout mice and a biochemical screen of interacting proteins reveal that exophilin-8 forms a large network of protein interactions to efficiently retain secretory granules beneath the plasma membrane for exocytosis.

    The biogenesis of CLEL peptides involves several processing events in consecutive compartments of the secretory pathway

    Nils Stührwohldt et al.
    Step-wise processing of plant peptide hormone precursors by subtilisin-like proteinases in consecutive compartments of the secretory pathway is required for formation and secretion of the bioactive peptides.

    Structural plasticity of dendritic secretory compartments during LTP-induced synaptogenesis

    Yelena D Kulik et al.
    The secretory and recycling components of neuronal dendrites, smooth endoplasmic reticulum and endosomes, were discovered to support synaptogenesis underlying a cellular mechanism of learning and memory in the developing brain.
