Endothelin association with the cultured rat Kupffer cell: Characterization and regulation
Katherine Stephenson, Stephen A. K. Harvey, Shamimunisa B. Mustafa, Ann T. Eakes, Merle S. Olson – 1 September 1995 – Circulating endothelin (ET) levels are elevated in conditions such as endotoxemia, hepatic ischemia‐reperfusion injury, or orthotopic liver transplantation, and this potent peptide may contribute to hepatic pathophysiology. We measured the surface binding of [125I]ET‐1 to rat Kupffer cells in primary culture at 4°C; the apparent dissociation constant (Kd) was 270 pmol/L, and the apparent Bmax was 3,000 receptors/cell.
