    SARS-CoV-2 entry into human airway organoids is serine protease-mediated and facilitated by the multibasic cleavage site

    Anna Z Mykytyn et al.
    Whereas SARS-CoV-2 utilizes cathepsins to enter most cell lines, human airway organoids revealed that entry into relevant cells is dependent on serine proteases, which can be targeted for treatment.

    Cancer-associated fibroblasts and their influence on tumor immunity and immunotherapy

    Richard Lee Barrett, Ellen Puré
    Long under-appreciated, fibroblast biology is a key aspect of understanding how the immune system responds to tumors and may hold the key to improving immunotherapy in this tricky space.

    Drosophila PDGF/VEGF signaling from muscles to hepatocyte-like cells protects against obesity

    Arpan C Ghosh et al.
    A muscle-derived signaling molecule suppresses excessive accumulation of lipids in the Drosophila adipose tissue by activating the Pi3K/Akt/mTOR signaling cascade in the Drosophila hepatocyte-like cells.

    Structural and functional characterization of G protein–coupled receptors with deep mutational scanning

    Eric M Jones et al.
    Linking deep mutational scanning with engineered transcriptional reporters in human cell lines establishes a generalizable method for exploring pharmacogenomics, structure, and function across broad classes of drug receptors.

    Lymphangiogenic therapy prevents cardiac dysfunction by ameliorating inflammation and hypertension

    LouJin Song et al.
    Lymphangiogenic therapy VEGFCc156s improved angiotensin-II-induced impairments in heart function via novel mechanisms, which include transcriptional responses to alleviate inflammation and cardiac fibrosis, and systemic responses to ameliorate hypertension.

    Increasing heart vascularisation after myocardial infarction using brain natriuretic peptide stimulation of endothelial and WT1+ epicardial cells

    Na Li et al.
    Brain natriuretic peptide supplementation can increase cardiac neovascularization in infarcted hearts by stimulating endogenous endothelial cell proliferation and proliferation of precursor cells, which will differentiate into endothelial cells.

    Meta-Research: COVID-19 research risks ignoring important host genes due to pre-established research patterns

    Thomas Stoeger, Luís A Nunes Amaral
    An analysis of 10,395 research publications about COVID-19 that mention at least one human gene reveals that many genes implicated in SARS-CoV-2 infection by genome-wide studies remain unstudied.

    ACE2: Evidence of role as entry receptor for SARS-CoV-2 and implications in comorbidities

    Natalia Zamorano Cuervo, Nathalie Grandvaux
    Despite evidence that ACE2 is the receptor for SARS-CoV-2, its limited expression in the respiratory system challenges the uniqueness of this entry route and role in the multifaceted COVID-19.
