Nature Neuroscience杂志发表的一项最新研究表明,男性和女性之间可能存在根本的痛觉差异。

科学家们首次发现,雄性小鼠和雌性小鼠用不同的细胞处理痛觉。这不仅有助于深入理解理解痛觉机制,帮助人们开发更好的药物治疗慢性痛,还会影响人们用小鼠进行基础生物医学研究的方式。

慢性痛是当今社会相当普遍的一种健康问题。据统计,世界上约有20-25%的人受到慢性痛的困扰,许多因素都可能引起慢性痛,包括神经损伤、关节炎、癌症甚至压力。

“之前的研究显示,男性和女性对疼痛的敏感度不同,而且女性更容易患上慢性痛。不过人们一直认为,男性和女性的痛觉处理应该是相同的,”文章的资深作者,McGill 大学的Jeffrey Mogil教授说。“认识到男性和女性的痛觉基础完全不同,这是非常重要的。”

过去的理论是,损伤或炎症位点的痛觉通过小胶质细胞在神经系统中传递。在这项新研究中只有雄性小鼠符合这一理论,干扰小胶质细胞的功能可以有效阻断雄性小鼠的痛觉,但对雌性小鼠却没有影响。

进一步研究表明,在雌性小鼠中传递痛觉信号的是一类完全不同的细胞(T细胞)。不过这一过程的具体机制还有待于进一步研究。

“我们正在开发更复杂更有针对性的下一代镇痛药物,理解痛觉通路的性别差异是非常必要的,”文章的另一位资深作者,多伦多大学的Michael Salter教授说。“我们相信小鼠的神经系统跟人类很相似,尤其是痛觉这样的基础进化功能。这意味着镇痛药物的开发面临着一个重要问题。”

近来,研究雌性动物和细胞越来越受重视。美国NIH不久前公布了新政策,要求临床前研究使用雌性动物和细胞系。

“十五年来科学家们一直认为是小胶质细胞控制着痛觉,但这是基于雄性小鼠研究得出的结论,”Mogil说。“从我们的研究可以看出,要想让所有人从科学研究中获益,实验设计就必须非常仔细。”
