Effects of allogeneic T cells on arterial graft function at 1 week in vivo. Transplanted human arterial segments were recovered from mice injected with saline (open squares) or PBMCs (filled squares) 7–9 days before harvest (n = 5 pairs from four experiments). (A–D) Response curves. Restriction response to various concentrations of PGF2α (A) and relaxation response curves for nitroprusside (B), bradykinin (C), or substance P (D) after preconstriction with PGF2α. *P < 0.05; **P < 0.01; #P < 0.001 vs. saline control. mN, milliNewtons. (E) Immunohistochemistry of graft sections stained for human and murine (inset) CD31, human CD45, and HLA-DR. The staining for human CD45 is indistinguishable from that for human CD3 (data not shown). Original magnification, ×200.
