and to analyze bradykinin B2 receptor expression in response to different doses of gamma-ray exposure. Cultured human foreskin fibroblasts (HF15) were irradiated with 0.5 Gy, 2.0 Gy, 5.0 Gy and 10.0 Gy single [...] e [3H]bradykinin. A dose and time dependant expression of the bradykinin B2 receptor was observed. Initially, higher doses (2 and 10 Gy) induced a fast upregulation of the receptor, followed by long lasting [...] t für Arbeitsforschung an der TU Dortmund Excli - Experimental and Clinical Sciences 2003 - Volume 2 Original Articles   Original Articles Permanent URI for this collection http://hdl.handle.net/2003/25601 …
