Cyclooxygenase-1 and -2-dependent prostacyclin formation in patients with atherosclerosis.

abstract：BACKGROUND:Prolonged survival of xenografted neonatal cardiomyocytes was achieved by blocking the CD28/B7 costimulatory pathway via CTLA4-Ig gene transfer. We examined the long-term survival of xenografted neonatal cardiomyocytes by adenovirus-mediated CTLA4-Ig expression and transient CD40 blockade with anti-CD40L mon...
