    Physiological and stem cell compartmentalization within the Drosophila midgut

    Alexis Marianes, Allan C Spradling
    The intestine contains distinct subregions specialized for digestion along its anterior-posterior axis, and the stem cells that constantly renew these subregions are not interchangeable.

    Cellular compartmentalisation and receptor promiscuity as a strategy for accurate and robust inference of position during morphogenesis

    Krishnan S Iyer, Chaitra Prabhakara ... Madan Rao
    An information theoretic and systems biology approach shows that cellular compartmentalisation and receptor promiscuity can facilitate the accurate and robust inference of position from noisy morphogen profiles, verified by experiments in Drosophila wing imaginal disc.

    Diffusive lensing as a mechanism of intracellular transport and compartmentalization

    Achuthan Raja Venkatesh, Kathy H Le ... Onn Brandman
    Agent-based modeling of space-dependent diffusivity inside cells reveals potential effects on biomolecule concentration and mesoscale dynamics.

    Compartmentalization and persistence of dominant (regulatory) T cell clones indicates antigen skewing in juvenile idiopathic arthritis

    Gerdien Mijnheer, Nila Hendrika Servaas ... Femke van Wijk
    In localized autoimmune disease, there is autoantigen-driven expansion of both effector T cell and Treg clones that are highly persistent and are (re)circulating, and might represent interesting therapeutic targets.

    Differential activation of JAK-STAT signaling reveals functional compartmentalization in Drosophila blood progenitors

    Diana Rodrigues, Yoan Renaud ... Maneesha S Inamdar
    Comprehensive developmental in situ analysis of the Drosophila lymph gland provides markers highlighting blood progenitor diversity and reveals that JAK-STAT signaling prevents posterior progenitor differentiation, promoting survival after immune challenge.

    Evidence for DNA-mediated nuclear compartmentalization distinct from phase separation

    David Trombley McSwiggen, Anders S Hansen ... Xavier Darzacq
    Transient DNA interactions by DNA-binding proteins are utilized by herpes simple virus as an alternative route to generate membraneless compartments in the nucleus without invoking phase separation.

    PDE2A2 regulates mitochondria morphology and apoptotic cell death via local modulation of cAMP/PKA signalling

    Stefania Monterisi, Miguel J Lobo ... Manuela Zaccolo
    The enzyme phosphodiesterase 2A2 localises at the mitochondrial membrane and its inhibition results in a local increase in cAMP concentration, mitochondrial elongation and resistance to apoptosis.

    Mixed cytomegalovirus genotypes in HIV-positive mothers show compartmentalization and distinct patterns of transmission to infants

    Juanita Pang, Jennifer A Slyker ... Judith Breuer
    Genomic analyses provide new insights into natural history and pathogenesis of cytomegalovirus infection and suggest new testable hypotheses that could be important for the design and implementation of new vaccines.

    Exocyst-mediated membrane trafficking of the lissencephaly-associated ECM receptor dystroglycan is required for proper brain compartmentalization

    Andriy S Yatsenko, Mariya M Kucherenko ... Halyna R Shcherbata
    Neuronal interacting proteome reveals that the cellular dynamics of the lissencephaly-associated extracellular matrix receptor dystroglycan are governed by the exocyst complex, which is key for proper brain assembly.

    Glucose restriction drives spatial reorganization of mevalonate metabolism

    Sean Rogers, Hanaa Hariri ... W Mike Henne
    Genetic and biochemical analyses, coupled with fluorescence imaging, reveal that spatial compartmentalization of HMG-CoA Reductases at yeast ER-lysosome contacts modulates mevalonate pathway flux during glucose restriction, enabling metabolic adaptation.
