Prostaglandin E2 (PGE2) is thought to be involved in the control of NaCl loading in the kidney. Since the ability to balance salt concentrations across the nephron appears to be impaired in the Spontaneously Hypertensive Rat (SHR), the uptakes of PGE by isolated medullary collecting tubule cells (MCT) from both SH and normotensive (NT) rats were compared. A rabbit antiserum directed against PGE2 revealed by flow cytometry the active internalisation of exogenous ligand by a high density fraction of intact MCT cells from NT tissue. Conversely, PGE2 uptake by the same fraction was markedly reduced. The monoclonal antibodies (MoAbs) W2.44 and SH6.6 raised against a 45,000 X g fraction of medullary tissue and which blocked binding of the anti-PGE2 serum, identified by Western blotting, an intracellular PGE2 receptor or binding protein (PGER) of 16 k daltons. No alteration in the structure or level of expression of this antigen could be detected in the MCT fractions isolated from the SHR. It is suggested that an impairment of PGE2 membrane transport in the renal medulla may be a contributory factor to the SH condition.
