GPCR-autoantibodies in cardiovascular diseases

Autoantibodies against G-protein coupled receptors (GPCR), most notably antibodies against beta-adrenergic receptors are a cause or risk factor for dilated cardiopathy and several other chronic cardiovascular diseases. These antibodies target definded activity-associated conformations of the receptors thereby altering receptor function. These conformational autoantibodies cannot be assessed in the usual manner by peptide-based immunoassays or staining of fixed tissues. Our current research interest focusses on the development validation and determination of of suitable procedures for measuring potentially pathogenic GPCR-autoantibodies and their predictive values for various dieseases
