Adrenalchromaffingranule(chromaffinvesicle)preparation
Adrenal chromaffin granule (chromaffin vesicle) preparationIntroduction. This prep is adapted from the classic paper of Smith and Winkler (Smith AD; Winkler H. A simple method for the isolation of adrenal chromaffin granules on a large scale. Biochemical Journal, 1967 May, 103(2):480-2). The method is usually used to prepare granules from freshly obtained (never frozen!) bovine adrenal glands, but can also be us......阅读全文
重磅！揭示肾上腺素能嗜铬细胞的一种新的细胞起源
肾上腺影响着许多过程，如应激反应和代谢。循环肾上腺素能够在体内产生深刻的影响，它的水平依赖于日常生活期间维持器官和身体平衡的需求发生变化。在比较极端的战斗或逃跑反应中，肾上腺素飙升，对器官和组织施加影响，包括增加的心率和血糖水平、将氧气和葡萄糖重新引导到四肢肌肉中。位于肾上腺髓质的嗜铬细胞（ch
