!--[if gte mso 9]> Angiotensin II is known as a peripheral hormone involved in the control of blood pressure and fluids homeostasis. The study and characterization of angiotensin II and its receptors at the brain has opened a new vision of its physiological role and also offers a variety of research fields. Brain angiotensin II is a well-documented neuromodulator of multiple brain circuits. In this sense, angiotensin II is involved in the stress response and both, the brain and the peripheral (hormonal), angiotensin II systems are stimulated during stress. Activation of brain angiotensin II AT1 receptors is required for the stress-induced hormone secretion, including corticotropin-releas
