    Muscle-specific stress fibers give rise to sarcomeres in cardiomyocytes

    Aidan M Fenix, Abigail C Neininger ... Dylan T Burnette
    Sarcomeres in heart muscle cells come from stress fiber-like structures that are mechanistically distinct from stress fibers in non-muscle cells.

    Targeting DNA topoisomerases or checkpoint kinases results in an overload of chaperone systems, triggering aggregation of a metastable subproteome

    Wouter Huiting, Suzanne L Dekker ... Steven Bergink
    Various genotoxic stresses trigger widespread aggregation of abundant, liquid-liquid phase separation-prone proteins, suggesting that genotoxic stress is a potential driver of disease-associated protein aggregation.

    The mechanism of MICU-dependent gating of the mitochondrial Ca2+uniporter

    Vivek Garg, Junji Suzuki ... Yuriy Kirichok
    A comprehensive functional analysis of mitochondrial Ca2+ uniporter (MCU) demonstrates that the auxiliary MICU subunits potentiate Ca2+ transport via MCU.

    Blood-brain barrier-restricted translocation of Toxoplasma gondii from cortical capillaries

    Gabriela C Olivera, Emily C Ross ... Antonio Barragan
    The invasion of Toxoplasma to the CNS across cortical capillaries is restricted by the integrity of the blood-brain barrier (BBB) and exacerbated by the inflammatory response.

    Regulated delivery controls Drosophila Hedgehog, Wingless, and Decapentaplegic signaling

    Ryo Hatori, Brent M Wood ... Thomas B Kornberg
    Delivery of Hedgehog, Decapentaplegic and Wingless to target cells in the Drosophila wing imaginal disc is regulated in both amount and destination, and is not dependent on constitutive release or uptake from a common pool.

    Competitive binding of STATs to receptor phospho-Tyr motifs accounts for altered cytokine responses

    Stephan Wilmes, Polly-Anne Jeffrey ... Ignacio Moraga
    IL-27 exerts differential activation of STAT1 and STAT3 via IL-27Ra and GP130, respectively, leading to a kinetic decoupling of its gene expression program, which contributes to tune its immuno-modulatory activities.
