COVID-19 Protein Disrupts Key Immune Response

Scientists have discovered a key way that the SARS-CoV-2 virus evades the immune system, making it harder for our bodies to fight off the infection. The virus's "nonstructural protein 1" (Nsp1) interferes with a critical pathway that helps our bodies respond to inflammation and infection, called the NF-κB pathway. By binding to a protein called TAK1, Nsp1 triggers its destruction, which in turn shuts down the NF-κB pathway. This means that the virus can suppress the immune system's response to the infection, leading to more severe symptoms and potentially worse outcomes.
