    Lack of IL-1R8 in neurons causes hyperactivation of IL-1 receptor pathway and induces MECP2-dependent synaptic defects

    Romana Tomasoni et al.
    Excessive inflammation of the brain in early life predisposes individuals to neurodevelopmental disorders by preventing synapses from developing correctly.

    Bystander hyperactivation of preimmune CD8+ T cells in chronic HCV patients

    Cécile Alanio et al.
    Naïve CD8+ T cells are dysregulated during chronic hepatitis C (HCV) infection, and this is reversible after viral clearance.

    Control of AMPA receptor activity by the extracellular loops of auxiliary proteins

    Irene Riva et al.
    Glutamate receptor auxiliary proteins exert their effects on receptor gating through two divergent extracellular loops, explaining subunit specificity and allowing the construction of null versions that form complexes normally but do not modify receptor gating.

    Ragulator and GATOR1 complexes promote fission yeast growth by attenuating TOR complex 1 through Rag GTPases

    Kim Hou Chia et al.
    The Rag-family GTPases, known activators of TOR complex 1 (TORC1), also function as attenuator that prevents deregulated hyperactivation of TORC1 signaling.

    Tumor suppressive role of sestrin2 during colitis and colon carcinogenesis

    Seung-Hyun Ro et al.
    Sestrin2 loss could be a universal mechanism of human colon carcinogenesis that allows for barrier dysfunction, mTORC1 hyperactivation, unrestricted tumor growth and chemoresistance.

    Luqin-like RYamide peptides regulate food-evoked responses in C. elegans

    Hayao Ohno et al.
    Identification and functional characterization of C. elegans luqin-like arginine-tyrosine-NH2 (RYamide) peptides reveal their critical role in feeding-related processes.

    A vitamin-B2-sensing mechanism that regulates gut protease activity to impact animal’s food behavior and growth

    Bin Qi et al.
    The availability of an essential dietary micronutrient is evaluated by an intestinal signaling system that in turn regulates food-uptake and response behaviors by modulating protease expression.

    Unfolded protein response transducer IRE1-mediated signaling independent of XBP1 mRNA splicing is not required for growth and development of medaka fish

    Tokiro Ishikawa et al.
    The unfolded protein response sensor/transducer IRE1-mediated splicing of XBP1 mRNA encoding its active downstream transcription factor to maintain the homeostasis of the endoplasmic reticulum is sufficient for growth and development of medaka fish.

    The LIM protein complex establishes a retinal circuitry of visual adaptation by regulating Pax6 α-enhancer activity

    Yeha Kim et al.
    Regulation of Pax6 expression through the α-enhancer fine-tunes amacrine cell subtype number, and consequently, the visual output of the retina.
