    Understanding genetic variants in context

    Nasa Sinnott-Armstrong, Stanley Fields ... Christine Queitsch
    Multiplexed assays of variant effect are an increasingly important tool in genetic research and including more context specificity in their design would aid interpretation and discovery.

    ESAT-6 undergoes self-association at phagosomal pH and an ESAT-6-specific nanobody restricts M. tuberculosis growth in macrophages

    Timothy A Bates, Mila Trank-Greene ... Fikadu G Tafesse
    ESAT-6, a virulence factor of Mycobacterium tuberculosis, dimerizes at neutral pH and transitions to oligomers under acidic pH similar to that of lysosome, helping the bacterium evade host defense mechanisms.

    Senescent cells inhibit mouse myoblast differentiation via the SASP-lipid 15d-PGJ2 mediated modification and control of HRas

    Swarang Sachin Pundlik, Alok Barik ... Arvind Ramanathan
    Senescent cells release an arachidonic acid-derived electrophilic oxylipin that inhibits myoblast differentiation by covalent modification and activation of HRas.

    The sterol-responsive RNF145 E3 ubiquitin ligase mediates the degradation of HMG-CoA reductase together with gp78 and Hrd1

    Sam A Menzies, Norbert Volkmar ... Paul J Lehner
    CRISPR/Cas9 genome-wide screens using sterol-sensitive endogenous HMG-CoA reductase (HMGCR) reporter identify the sterol-responsive RNF145 and gp78 as independently responsible for sterol-accelerated degradation of HMGCR, the rate-limiting enzyme of cholesterol biosynthesis.

    MHC-compatible bone marrow stromal/stem cells trigger fibrosis by activating host T cells in a scleroderma mouse model

    Yoko Ogawa, Satoru Morikawa ... Shigeto Shimmura
    PDGFRα+ Sca-1+ bone marrow stromal/stem cells in whole bone marrow grafts can trigger the onset of autoimmune-related fibrosis in a mouse model of scleroderma.

    Process- and product-related impurities in the ChAdOx1 nCov-19 vaccine

    Lea Krutzke, Reinhild Rösler ... Stefan Kochanek
    Analysis of protein content and protein composition of the ChAdOx1 nCov-19 vaccine, but not of the Ad26.COV2.S vaccine, indicated significantly higher than expected levels of host cell proteins (HCPs) and of free viral proteins.
