瘦素是一种重要的摄食中枢激素。在发育过程中,胎儿和新生儿暴露于瘦素,最近的证据表明,瘦素受体广泛分布于整个发育中的大脑。因此,瘦素在出生前和出生后都会影响大脑发育。瘦素在发育中的大脑中的作用通常是永久性的,范围从下丘脑回路的建立到皮质通路的可塑性。瘦素介导的细胞事件包括:神经发生、轴突生长和突触发生。营养操纵瘦素分泌在围产期的生活已经产生了相当大的关注,发育中的大脑似乎是一个特别敏感的目标,这些环境的变化。
Leptin is well known as an important hormone in the central control of feeding behavior. During development, fetuses and newborns are exposed to leptin and recent evidence has shown that leptin receptors are widespread throughout the developing brain. Accordingly, leptin affects brain development during both pre- and post-natal life. The actions of leptin in the developing brain are generally permanent and range from the establishment of hypothalamic circuits to plasticity in cortical pathways. The cellular events mediated by leptin include the following: neurogenesis, axon growth, and synaptogenesis. Nutritional manipulation of leptin secretion during perinatal life has generated considerable concern, and the developing brain appears to be a particularly sensitive target for these environmental changes.
