Abstract excerpt
BACKGROUND: Cellular rejection of xenografts is predominantly mediated by CD4 T cells. Little is known of the effectiveness of CD4CD25 T regulatory (Treg) cells at suppressing this strong T-cell mediated immune response. In this study, we evaluated the activity of fresh Treg cells and expanded Treg cells to suppress the xeno immune response in vitro. METHODS: Human Treg cells were preferentially expanded by...
