| Abstract: | We localized and characterized angiotensin II AT1 and AT2 receptors in the skin of 2-week-old rats during experimental wound healing. Both AT1 and AT2 were present in the skin. Three days after wounding, the expression of angiotensin II receptors was significantly enhanced in the dermis as well as in a localized band within the superficial dermis of the skin surrounding the wound. The major proportion of this increase was due to angiotensin II AT2 receptors. Our results suggest a physiological role for AT2 receptors in the process of tissue repair. |
