GLIAL细胞系衍生的神经营养因子(GDNF)是胚胎中脑多巴胺能(1)、脊髓运动(2)、颅感觉(3)、交感神经和后脑去甲肾上腺素能(4)神经元的有效存活因子,并且在体内可用于这些细胞。因此,它被认为是一种生理营养因子和帕金森病(5,6),肌萎缩侧索硬化(7)和阿尔茨海默病(4)的潜在治疗剂。在这里,我们表明,在出生后0天(P0),GDNF缺陷小鼠有赤字,背根神经节,交感神经元和结状神经元,但不是在后脑去甲肾上腺素能或中脑多巴胺能神经元。这些小鼠完全缺乏肠神经系统(ENS)、输尿管和肾脏。因此,GDNF对于肠神经元、交感神经元和感觉神经元以及肾系统的发育和/或存活是重要的,但对于中枢神经系统(CNS)中的儿茶酚胺能神经元不是必需的。
GLIAL cell-line derived neurotrophic factor (GDNF) is a potent survival factor for embryonic midbrain dopaminergic(1), spinal motor(2), cranial sensory(3), sympathetic, and hindbrain noradrenergic(4) neurons, and is available to these cells in vivo. It is therefore considered a physiological trophic factor and a potential therapeutic agent for Parkinson's disease(5,6), amyotrophic lateral sclerosis(7), and Alzheimer's disease(4). Here we show that at postnatal day 0 (P0), GDNF-deficient mice have deficits in dorsal root ganglion, sympathetic and nodose neurons, but not in hindbrain noradrenergic or midbrain dopaminergic neurons. These mice completely lack the enteric nervous system (ENS), ureters and kidneys. Thus GDNF is important for the development and/or survival of enteric, sympathetic and sensory neurons and the renal system, but is not essential for catecholaminergic neurons in the central nervous system (CNS).
