    Role of N343 glycosylation on the SARS-CoV-2 S RBD structure and co-receptor binding across variants of concern

    Callum M Ives, Linh Nguyen ... Elisa Fadda
    Viral evolution can lead to mutations that render specific glycosylation sites dispensable for folding and for supporting the protein's function, allowing changes in the shield, and in the immunogenic profile.

    Coronary blood vessels from distinct origins converge to equivalent states during mouse and human development

    Ragini Phansalkar, Josephine Krieger ... Kristy Red-Horse
    Endothelial cells from separate cardiac lineages start off in distinct transcriptional states, but over the course of development converge into transcriptional and functional states which are unrelated to lineage and which are conserved between mouse and human.

    Common host variation drives malaria parasite fitness in healthy human red cells

    Emily R Ebel, Frans A Kuypers ... Elizabeth S Egan
    Human red blood cells from healthy donors display marked biophysical and genetic variation that impacts the growth of Plasmodium falciparum malaria parasites, outside of known disease alleles.

    The malaria parasite sheddase SUB2 governs host red blood cell membrane sealing at invasion

    Christine R Collins, Fiona Hackett ... Michael J Blackman
    Genetic analysis identifies an enzyme of the malaria parasite that is required to seal its host red blood cell membrane upon invasion, a key requirement of this important intracellular pathogen.

    Piezo1 as a force-through-membrane sensor in red blood cells

    George Vaisey, Priyam Banerjee ... Roderick MacKinnon
    Super-resolution microscopy and single particle tracking analysis of Piezo1 in red blood cells demonstrate its ability to sense membrane curvature, consistent with a force-through-membrane mechanism of channel mechanosensation in these cells.

    Piezo1 links mechanical forces to red blood cell volume

    Stuart M Cahalan, Viktor Lukacs ... Ardem Patapoutian
    In red blood cells, the Piezo1 protein is responsible for sensing mechanical forces and volume regulation.

    NK cells inhibit Plasmodium falciparum growth in red blood cells via antibody-dependent cellular cytotoxicity

    Gunjan Arora, Geoffrey T Hart ... Eric O Long
    Red blood cells infected by the malaria parasite Plasmodium falciparum are destroyed by human natural killer cells in the presence of antibodies from people who have acquired clinical immunity to malaria.

    Addressing shortfalls of laboratory HbA1c using a model that incorporates red cell lifespan

    Yongjin Xu, Richard M Bergenstal ... Ramzi A Ajjan
    The person-specific adjusted HbA1c addresses non-glycaemic variation in laboratory HbA1c due to red blood cell lifespan differences, potentially providing a better marker to predict diabetes complications and guide glycaemic management.

    Variability of cholesterol accessibility in human red blood cells measured using a bacterial cholesterol-binding toxin

    Rima S Chakrabarti, Sally A Ingham ... Helen H Hobbs
    Accessible cholesterol levels in human red blood cells were found to be stable within individuals but vary >10-fold among individuals and this variability may contribute to differences in cholesterol trafficking among tissues.

    Determinants shaping the nanoscale architecture of the mouse rod outer segment

    Matthias Pöge, Julia Mahamid ... Wolfgang Baumeister
    Cryo-electron tomography of close-to-native rod outer segments resolves connectors between disks and a scaffold at the disk rim enforcing the high membrane curvature of the unique long-range organization in these rhodopsin-rich light-sensitive subcellular organelles.
