The recruitment of monocytes via the endothelial expression of vascular cell adhesion molecule-1 (VCAM-1) is a key step in the formation of the initial lesion in atherosclerosis. Because angiotensin (Ang) II may be involved in this process, we investigated its role on the signaling cascade leading to VCAM-1 expression in endothelial cells. Ang II stimulates(More)
Angiotensin I-converting enzyme (ACE; kininase II) contains two very similar domains (the NH2- and COOH-terminal domains (N and C domains, respectively)), each bearing an active site. These active sites hydrolyze the same peptides, but do not have the same catalytic properties and substrate specificities. In an attempt to develop domain-specific(More)

OBJECTIVE To develop and validate a simple immunological assay for human angiotensin converting enzyme (ACE) based on monoclonal antibodies. METHODS Microtitre plates were coated with mouse monoclonal antibody (MoAb) to human ACE (9B9) and incubated with diluted samples of human plasma. In the sandwich enzyme-linked immunosorbent assay (ELISA), the plasma(More)
T Kininogen and High Molecular Weight Kininogen were characterized in the cell culture medium of Fao cells, a highly differentiated cell line derived from the Reuber H35 rat hepatoma. Immunoreactive T Kininogen and High Molecular Weight Kininogen identified by direct and specific RIAs were indistinguishable from standard kininogens. Immunoreactive T(More)

1. The renin-angiotensin and kinin-kallikrein systems of Dahl salt-sensitive and salt-resistant rats fed diets with different salt contents were analysed using biochemical and immunocytochemical techniques. 2. Blood pressure increased by 45% in salt-sensitive rats only, after 4 weeks on a high-salt diet. The plasma renin activity and plasma angiotensin II(More)
Rat T-kininogens were characterized in plasma, urine and liver slice incubation medium in different physiological conditions using monoclonal antibodies that allow to distinguish between the two forms of T-kininogen. T-kininogen purified from the plasma of both normal and inflamed Wistar and Sprague-Dawley rats was found to contain the two forms of(More)
The thyroid state affects the inflammatory reaction; in general, thyroid hormones increase and hypothyroidism decreases the inflammatory response. T-kininogen is an acute phase protein that inhibits cysteine proteases. The influence of thyroidectomy and 3,5,3'-triiodothyronine (T3)-treatment of thyroidectomized animals was examined on rat plasma T-kininogen(More)
