Memory regulatory T cells (mTregs) have been demonstrated to persist long-term in hosts after the resolution of primary influenza A virus (IAV) infection. However, whether such IAV infection-experienced (IAV-experienced) mTregs differentiate into a phenotypically and functionally distinct Treg subset and what function they play at the infection site remains poorly defined. In this study, we characterized the phenotype, examined the responsiveness and assessed the suppressive function of IAV-experienced memory Tregs (mTregs). In comparison with inexperienced naïve Tregs (nTregs), mTregs exhibited elevated expression of CD39, CD69, CD103, cytotoxic T lymphocyte-associated antigen-4, leukocyte ..
