    Disease consequences of higher adiposity uncoupled from its adverse metabolic effects using Mendelian randomisation

    Susan Martin, Jessica Tyrrell ... Hanieh Yaghootkar
    Using genetics, it is possible to uncouple higher adiposity from its adverse metabolic effects and show that some obesity-associated conditions may benefit from treating the metabolic effects alone, whilst others may benefit more from weight loss.

    Multi-ancestry meta-analysis of host genetic susceptibility to tuberculosis identifies shared genetic architecture

    Haiko Schurz, Vivek Naranbhai ... International Tuberculosis Host Genetics Consortium
    Results from the largest tuberculosis genome-wide association study meta-analysis identified a significant association in the human leukocyte antigen class II region, rs28383206, across multiple populations.

    A conserved major facilitator superfamily member orchestrates a subset of O-glycosylation to aid macrophage tissue invasion

    Katarina Valoskova, Julia Biebl ... Daria E Siekhaus
    T antigen glycosylation, which marks metastatic cancer cells, is modulated on a small set of proteins by a conserved multipass transmembrane protein to allow tissue invasion by Drosophila macrophages.

    ATR expands embryonic stem cell fate potential in response to replication stress

    Sina Atashpaz, Sara Samadi Shams ... Vincenzo Costanzo
    ATR protects stem cell genomes by activating a transcriptional response mediated by totipotency genes, conferring trophoblast differentiation potential, the derepression of which in somatic cells might favour cancer features emergence.

    Interneuronal mechanisms of hippocampal theta oscillations in a full-scale model of the rodent CA1 circuit

    Marianne J Bezaire, Ivan Raikov ... Ivan Soltesz
    Spontaneous theta oscillations and interneuron-specific phase preferences emerge spontaneously in a full-scale model of the isolated hippocampal CA1 subfield, corroborating and extending recent experimental findings.

    Expansion and loss of sperm nuclear basic protein genes in Drosophila correspond with genetic conflicts between sex chromosomes

    Ching-Ho Chang, Isabel Mejia Natividad, Harmit S Malik
    Genetic conflicts between sex chromosomes during spermatogenesis may drive the rapid evolution, function, and turnover of some sperm nuclear basic proteins in Drosophila species.

    TNFR1-dependent cell death drives inflammation in Sharpin-deficient mice

    James A Rickard, Holly Anderton ... John Silke
    Skin inflammation in Sharpin-deficient mice is primarily due to TNFR1-dependent apoptosis, but necroptosis appears to play a bigger role in inflammation of internal organs.

    Two new polymorphic structures of human full-length alpha-synuclein fibrils solved by cryo-electron microscopy

    Ricardo Guerrero-Ferreira, Nicholas MI Taylor ... Henning Stahlberg
    Two new polymorphic structures of recombinant human alpha-synuclein fibrils show striking differences to previous structures, while familial PD mutation sites remain crucial for protofilament interaction and fibril stability.

    Internal amino acid state modulates yeast taste neurons to support protein homeostasis in Drosophila

    Kathrin Steck, Samuel J Walker ... Carlos Ribeiro
    Two different classes of taste receptor neurons in the Drosophila melanogaster proboscis play distinct roles in yeast feeding and are both modulated by the fly's internal amino acid state in order to promote protein-specific appetite.

    Stem cell regionalization during olfactory bulb neurogenesis depends on regulatory interactions between Vax1 and Pax6

    Nathalie Coré, Andrea Erni ... Harold Cremer
    Vax1 suppresses dopaminergic neuron phenotype by inhibiting Pax6 expression in the subventricular zone of the lateral ventricle and is necessary to generate Calbindin interneurons for the postnatal olfactory bulb.
