WebCarboxyfluorescein succinimidyl ester (CFSE)-based in vivo cytotoxicity assays enable sensitive and accurate quantitation of CD8 + cytolytic T lymphocyte (CTL) responses elicited against tumor- and pathogen-derived peptides. They offer several advantages over traditional killing assays. WebSince normally Tregs only constitute 5-10% of peripheral CD4(+) T cells, this advantage is noteworthy compared with other methods. With the assay we developed, we demonstrated that regulatory T cells (Tregs) could inhibit the antigen-specific killing of an adherent target cell monolayer by the CD8(+) cytotoxic T cells. stevens point wi voting resultsWebNational Center for Biotechnology Information stevens point wisconsin airport code
