Description:

The endothelin axis (endothelins and their receptors) is strongly involved in physiological and pathological processes. ET-1 plays a crucial role in particular in tumor diseases. Endothelin-1 receptors (ETA and ETB) are deregulated and overexpressed in several tumors such as melanoma and glioma. We studied the binding of 24 monoclonal antibodies directed against human ETB receptors (hETB) to different melanoma cell lines. Few of these mAbs bound to all the melanoma cell lines. One of them, rendomab B49, bound to ETB receptors expressed at the surface of human glioma stem cells. More recently, we produced new antibodies directed against human ETA receptor (hETA). Several antibodies have been isolated and have been screened on different tumoral cells lines. As for the mAbs directed against the hETB receptor only some of new antibodies directed against ETA receptor are capable to bind the human tumoral cell lines. Rendomab A63 directed against hETA is one of them. We report the specificity and binding properties of these mAbs and consider their potential use in diagnosis by an in vivo imaging approach., A.
