T cells and B cells play key roles in adaptive immunity against the IAV infection. T cells are mainly known as CD4+ T and CD8+ T cells. CD8+ T cells differentiate into cytotoxic T lymphocytes (CTLs), which produce cytokines and effector molecules to restrict viral replication and kill virus-infected cells.
