Abstract excerpt
Human metapneumovirus (HMPV) is a leading cause of respiratory tract infection in pediatric, elderly, and immunocompromised populations. Clearance of HMPV relies primarily on the destruction of infected cells by cytotoxic CD8+ T cells. However, signals provided by CD4+ helper T cells significantly impact the magnitude and effectiveness of CD8+ T cells. The role of CD4+ helper T cells in the immune response to...
