Abstract
The spontaneously hypertensive rat (SHR) is a model widely used to investigate the causal mechanisms of essential hypertension. The enhanced catecholamine (CA) release reported in adrenal glands from adult SHRs raised considerable interest for its possible implication in the genesis of hypertension. The use of powerful techniques such as calcium imaging, electrophysiology, and single-cell amperometry to monitor in real time the key steps in CA secretion has allowed a better understanding of the role of chromaffin cells (CC) in the pathophysiology of hypertension, although several questions remain. Additionally, the implementation of these techniques in preparations in situ, such as the acute adrenal gland slice, which maintains the microenvironment, cell-to-cell communication, and anatomical structure similar to that of the intact adrenal gland, yields data that may have even greater physiological relevance. Here, we describe the procedures to measure the blood pressure of rats in a noninvasive manner, how to obtain primary cultures of adrenal chromaffin cells and acute adrenal slices, and how to perform amperometric recordings and intracellular calcium imaging in these preparations.
