在女性衰老和绝经过渡期间,发生进行性肌肉退化(即质量和肌肉功能下降)。这种肌肉功能障碍是由肌肉卫星细胞增殖减少、炎症标志物水平升高和性激素水平改变引起的,使妇女患肌肉减少症的发病率升高。在这方面,激素平衡,特别是雌二醇,似乎是必不可少的骨骼肌功能。本文综述了雌二醇对绝经期妇女卫星细胞和炎性细胞因子释放的作用。特别是,雌二醇通过刺激卫星细胞增殖对骨骼肌具有有益作用。骨骼肌可以响应雌激素的控制,因为在肌纤维水平上存在雌二醇的特异性受体。此外,雌二醇可以限制骨骼肌的炎症应激损伤。在这篇综述中,我们主要关注雌二醇在肌肉减少症中的作用,以及使用雌二醇替代疗法的可能性,该疗法结合营养和体育活动计划,可以抵消这种情况,是治疗女性肌肉减少症的有效工具。
During aging and menopausal transition in women, a progressive muscle degeneration (i.e. decrease in quality and muscle function) occurs. This muscle dysfunction, caused by decreased proliferation of muscle satellite cells, increased levels of inflammatory markers, and altered levels of sex hormones, exposes women to a raised incidence of sarcopenia. In this regard, hormonal balance and, in particular, estradiol, seems to be essential in skeletal muscle function. The role of the estradiol on satellite cells and the release of inflammatory cytokines in menopausal women are reviewed. In particular, estradiol has a beneficial effect on the skeletal muscle by stimulating satellite cell proliferation. Skeletal muscle can respond to estrogenic hormonal control due to the presence of specific receptors for estradiol at the level of muscle fibers. Additionally, estradiol can limit inflammatory stress damage on skeletal muscle. In this review, we primarily focused on the role of estradiol in sarcopenia and on the possibility of using Estradiol Replacement Therapy, which combined with nutritional and physical activity programs, can counteract this condition representing a valid tool to treat sarcopenia in women.
