- 内分泌学 在内分泌学.
- 生殖生物学 生殖生物学
背景情况:
- 多囊卵巢综合征 (PCOS) 与低度炎症有关.
- 在PCOS中,高雄性特征对免疫系统的具体影响尚不清楚.
研究的目的:
- 为了研究超原体主义如何影响各种组织中的免疫细胞群.
- 为了确定这些效应是否由雄激素受体激活介导.
- 探索这些免疫变化与PCOS类特征之间的联系.
主要方法:
- 使用一个PCOS类型的小鼠模型,暴露在二铁 (DHT) 中.
- 在并发治疗时使用雄激素受体抗剂.
- 分析了生殖,代谢 (内脏脂肪组织-VAT) 和免疫组织中的免疫细胞群和标记物.
- 评估胰岛素耐药性和脂肪质量.
主要成果:

Oogenesis
63.7K
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

Hormonal Regulation of the Menstrual Cycle
345
The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...
