神经组织将睾酮芳构化为雌二醇的过程通常与性别化、促性腺激素分泌和交配行为的调节有关。然而,新的数据表明芳香化能力并不局限于内分泌脑,并证明了局部形成的雌激素在神经发生和脑组织损伤反应中的作用。本文总结了我们目前对芳香酶在大脑中的分布和调节的理解,并讨论了它所起的经典和新的作用。更好地了解大脑芳构化可以揭示其生理和病理功能,并有一天导致新的集中作用药物治疗。
Aromatization of testosterone to estradiol by neural tissue has classically been associated with the regulation of sexual differentiation, gonadotropin secretion, and copulatory behavior. However, new data indicate that the capacity for aromatization is not restricted to the endocrine brain and demonstrate roles for locally-formed estrogens in neurogenesis and in responses of brain tissue to injury. This manuscript summaries our current understanding of the distribution and regulation of aromatase in the brain and discusses the classical and novel roles it plays. A better understanding of brain aromatization could shed new light on its physiologic and pathologic functions and someday lead to new centrally acting drug therapies.
