WebApr 13, 2024 · Our findings reveal a hitherto uncharacterized mechanism whereby SARS-CoV-2 infection induces the predominant expression of unproductive splicing isoforms in key IFN signaling genes, interferon-stimulated genes (ISGs), class I MHC genes, and splicing machinery genes, including IRF7, OAS3, HLA-B, and HNRNPH1. WebThe first step is binding to antigen presented on MHC. The second step is usually the cell (let’s say it’s a dendritic cell) has a ligand that it expresses that will bind to a receptor on the T-cell. So in order for a T-cell to be activated both of these things must happen. terminal h jeddah
