B2 receptor loss may promote hypertension and remodeling in mice; hypothesis-generating for kinin cardioprotection, requiring human validation.
Does the absence of bradykinin B2 receptors affect cardiac structure and function in mice?
Disruption of the bradykinin B2 receptor in mice leads to hypertension, LV remodeling, and functional impairment, demonstrating the essential role of kinins in preserving cardiac structure and function.
