J Neurosci Res:大脑活动的性别差异改变疼痛疗效

2017-03-15 佚名 生物360

根据乔治亚洲立大学最近的一项研究显示,女性大脑中参与疼痛调节的定植免疫细胞区域相对于男性更为活跃。



根据乔治亚洲立大学最近的一项研究显示,女性大脑中参与疼痛调节的定植免疫细胞区域相对于男性更为活跃。

女性患纤维肌痛和骨关节炎等慢性和炎性疼痛疾病的概率较高,虽然吗啡仍然是治疗疼痛的主要药物之一,但是对女性的效果通常较差。

“事实上,临床临床前期研究报告显示,女性使用吗啡的剂量为男性的两倍,才能产生类似的效果,”乔治亚洲神经科学研究 Murphy 实验室的研究生 Hillary Doyle 说到,“我们对于这种现象可能的解释是大脑小胶质细胞存在性别差异。”

在健康人中,小胶质细胞作为寻找感染或病原体的特征。在没有疼痛的情况下,吗啡能干扰正常的生理功能,并被视为病原体激活大脑的免疫细胞进而引起炎症因子的释放。

为了检测性别差异如果影响吗啡的疗效,Doyle 分别给予雄性和雌性大鼠抑制小胶质细胞活化的药物。

“这项研究结果对于疼痛的治疗有重要影响,表明小胶质细胞可能是提升阿片类药物对女性治疗效果的重要靶点,” Anne Murphy 博士说到。

研究发现小胶质细胞在大脑疼痛相关的区域更加活跃,这可能有助于解释为什么各种慢性疼痛综合征在女性的发病率明显高于男性。
