Measles Virus exits via ______ epithelium

[Blank] is the first discovered viral receptor for influenza

There are three different receptors for the viral entry into the host cell: 1. [Blank] 2. MCP/CD46 o compliment binding protein 3. PVRL4/Nectin 4

The measles virus exits the cell by fusing into ________.

Nectin 4 is present between ________ in the respiratory tract.

The virus within T, B, and dendritic cells will bind to ________ and gain entry into epithelial cells.

SLAM and ________ are the two receptors used by wild-type MeV to infect and exit its human host.

Using a pseudotype virus has the advantage of allowing researchers to work on the SARS cov2 research in a ______ facility.

One limitation of using a pseudotype virus is that you don't know the role of other ______ proteins.

In the study, the spike protein of SARS cov2 demonstrated ______ activity.

When expressing the spike protein of SARS cov2 in cells, the researchers observed cleavage into S1 and S2, providing ______ evidence of cleavage.

Which receptor does SARS-CoV-2 bind to?

What is the function of the fusion peptide proximal region (FPPR) in SARS-CoV-2 membrane fusion?

What is the post-fusion structure of S2 responsible for?

What is the purpose of the second cleavage in SARS-CoV-2 membrane fusion?

mRNA vaccines have a ______ locked state of spike in their surface so that they don’t have - Lock spike in its pre-fusion state so that when it is expressed, it is only existing in the S1/S2 complex --. There is no post fusion spike that is being made Only post fusion S2 on the surface of the vriions

The S1 and S2 exists in the trimer form and are recognized by ______

There is already a prefusion cleavage between S1 and S2 by ______ but TMPRSS2 can also cleave but it predominantly cleaves at the S2 prime site and the S2 prime site is important for S1 fall off and expose major conformational changes in S2 exposes the fusion peptide which allows the virus to engage with target cellular protein. Fusion of viral post membrane and release of contents into the cytosol

This study showed that ______ is important for cells that are TMPRSS2 + for SARS-CoV-2 to enter the cell, but TMPRSS2 - cells can't fuse through the cell membrane and inhibiting ______ results in no infection. Inhibition of cathepsin B had no major affect on the ability of SARS-CoV-2 to enter the cell
