摘要: Both CD4 + and CD8 human memory but not naive T cells respond to allogeneic dermal microvascular endothelial (HDMEC) in vitro by secreting cytokines proliferating. Several recently identified costimulators, namely, 4-1BB ligand, ICOS OX40 are up-regulated on cultured HDMEC response TNF or coculture with cells. Blockade of these costimulators each partially reduces IFN-γ IL-2 secretion proliferation previously resting The effects overlapping identical. Memory the principal effectors injury skin allografts following adoptive transfer into immunodeficient mice. Furthermore, blocking ligand this model allograft cell effector molecule expression. These data demonstrate that can injure vivo without priming. several described contribute processes.
