Expression of TGF-beta receptors type I and II in human glomerulonephritis.

Abstract

Our data show that TGF-beta expression is a good indicator of the severity of proliferative glomerular lesions in most, if not all cases and that RI-RII expression occurs at levels detectable with indirect immunofluorescence in limited number of glomerulonephritides, mostly associated with systemic diseases. A complex interaction between TGF-beta and its ligand may represent a critical factor conditioning the tissue response to immunological injury.
