COVID-19: Immune cells targeting core protein are important for early immune defense

A study has identified a key component of the adaptive immune response to SARS-CoV-2 infection: nucleocapsid-specific T cells. These cells recognize and kill virus-infected cells, controlling viral replication and inflammation in the upper airways. The findings suggest that vaccines targeting this protein could be more effective.
