Interaction between filovirus glycoprotein (GP) and the Niemann-Pick C1 (NPC1) protein is essential for membrane fusion during virus entry. Some single-nucleotide polymorphism (SNPs) in two surface-exposed loops of NPC1 are known to reduce viral infectivity. However. the dependence of differences in entry efficiency on SNPs remains unclear. https://www.marketingjeunesse.com/product-category/replacement-t-blade/
