    Self-organization of modular network architecture by activity-dependent neuronal migration and outgrowth

    Samora Okujeni, Ulrich Egert
    Activity-dependent neurite outgrowth and neuronal migration interact to shape modular mesoscale network architecture by homeostatic self-organization.

    Repression of ferritin light chain translation by human eIF3

    Mia C Pulos-Holmes et al.
    Human ferritin light chain (FTL) mRNA translation is regulated via its 5'-untranslated region (5'-UTR) by three mechanisms: RNA folding, iron response protein binding, and eukaryotic translation initiation factor eIF3 binding.

    Homeostatic reinforcement learning for integrating reward collection and physiological stability

    Mehdi Keramati, Boris Gutkin
    A mathematical model built around the assumption that the desire to maintain internal homeostasis drives the behavior of animals, by affecting their learning processes, can explain many real-world behaviors, including some that might otherwise appear irrational.

    Evolution of (p)ppGpp-HPRT regulation through diversification of an allosteric oligomeric interaction

    Brent W Anderson et al.
    The signaling ligand (p)ppGpp regulates the enzyme HPRT across species by binding to a novel class of conserved motif, yet its specificity is allosterically altered through evolution of enzyme oligomerization.

    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.

    Sleep-promoting effects of threonine link amino acid metabolism in Drosophila neuron to GABAergic control of sleep drive

    Yoonhee Ki, Chunghun Lim
    Threonine promotes sleep via down-regulation of metabotropic GABA transmission in the ellipsoid body R2 neurons that generate homeostatic sleep drive in Drosophila.

    Drosophila neprilysins control insulin signaling and food intake via cleavage of regulatory peptides

    Benjamin Hallier et al.
    The catalytic activity of a Drosophila neprilysin is critical to proper insulin expression and food intake by regulating homeostasis of distinct signaling peptides.

    A novel role for lipoxin A4 in driving a lymph node–eye axis that controls autoimmunity to the neuroretina

    Jessica Wei et al.
    LXA4 in lymph nodes is an important resident homeostatic regulator that controls effector T cell functions and egress in the development of adaptive immune responses.

    Genetic analysis reveals functions of atypical polyubiquitin chains

    Fernando Meza Gutierrez et al.
    A comprehensive genetic interaction screen uncovered biological roles of K11 linkages in amino acid homeostasis and cell cycle regulation in yeast.

    Mitochondrial flashes regulate ATP homeostasis in the heart

    Xianhua Wang et al.
    Mitochondrial flashes counteract the imbalance of ATP supply-and-demand and constitute an auto-regulator of ATP homeostasis in the heart.
