Research Abstract

Adipocyte-derived leucine amnopeptidase (A-LAP) may play role in the blood pressure regulation. In this study, it is revealed that ER-retained A-LAP is secreted from macrophages in response to activation by treatment with lipopolysaccharide and interferon-γ, and supply of arginine for nitric oxide synthesis from peptide to cells. These results suggest that secretion of A-LAP is important for hypertensive action.
