摘要
Since its discovery and molecular characterization, the angiotensin AT(2)-receptor has been enigmatic with respect to signalling pathways and function. Evidence now emerges that angiotensin II exerts actions through the AT(2) receptor which are directly opposed to those mediated by the AT(1) receptor. This can be exemplified e.g. by mutually antagonizing effects on cell growth. Upregulated by the endogeneous agonist itself, as well as by several growth- and differentiating factors in development and tissue injury, the AT(2) receptor appears to act as a modulator of complex biological programmes involved in embryonic development, cell differentiation, tissue protection and regeneration, as well as in programmed cell death. Research on the AT(2) receptor has thus unveiled hitherto unknown functions of the renin-angiotensin system extending far beyond the classical role of this old hormonal system in cardiovascular control.
