Interferon-induced transmembrane proteins (IFITMs) inhibit infection of diverse enveloped viruses. including the influenza A virus (IAV) which is thought to enter from late endosomes. Recent evidence suggests that IFITMs block virus hemifusion (lipid mixing in the absence of viral content release) by altering the properties of cell membranes. Consistent with this mechanism. https://jalyttlers.shop/product-category/highball-glasses/
