Sex-linked Disorders

103.0K
Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

概括

多发性硬化症 (MS) 病变中的荷尔蒙差异显示女性的神经活性类固醇产量增加和雄激素水平改变,这可能解释基于性别的疾病进展. 类固醇在体外也影响了质细胞的反应.

科学领域:

  • 神经免疫学 神经免疫学
  • 内分泌学 在内分泌学.
  • 多发性硬化症的发病因子

背景情况:

  • 多发性硬化症 (MS) 易感性和进展的性别差异表明荷尔蒙参与.
  • 之前的发现表明,在MS病变中,性别之间存在不同的类固醇酶表达.

研究的目的:

  • 测量活跃,不活跃和复髓化MS病变中的类固醇水平,并控制白质.
  • 研究性激素对MS患者的质细胞的体外影响.

主要方法:

  • 气色谱-质谱法 (GC/MS) 用于量化MS病变中的类固醇水平和控制白质.
  • 分析了类固醇受体和酶的基因表达.
  • 试验室研究评估了雌激醇 (E2),孕和对初级微质细胞和星体细胞的影响.

主要成果:

  • 女性多发性硬化病变呈现出增加的阿洛普雷格纳和降低的代谢产物和脱水氨 (DHEA).
  • 男性MS病变的类固醇变化最小,5α-DHDOC略有增加.
  • 雷米林化病变没有显示任何类固醇水平差异,但女性的类固醇受体和AKR1C3基因表达率较高.
  • 在体外,性激素在炎症条件下在质细胞中有益调节细胞因子和神经保护性基因表达.

结论:

  • 在MS病变中的类固醇水平和新陈代谢的性别特异性变化可能会导致疾病进展的差异.
  • 激素对质细胞反应的影响可能在MS的发病和病变解决中发挥作用.
  • 对多发性硬化症的荷尔蒙疗法进行进一步的研究是有必要的.
