Chronic pain is a major burden for the society and remains more prevalent and severe in females. The presence of chronic pain is linked to persistent alterations in the peripheral and the central nervous system. One of the main types of peripheral pain transducers are the transient receptor potential channels (TRP), also known as thermoTRP channels, which intervene in the perception of hot and cold external stimuli. These channels, and especially TRPV1, TRPA1 and TRPM8, have been subjected to profound investigation because of their role as thermosensors and also because of their implication in acute and chronic pain. Surprisingly, their sensitivity to endogenous signaling has been far less studied. Cumulative evidence suggests that the function of these channels may be differently modulated in males and females, in part through sexual hormones, and this could constitute a significant contributor to the sex differences in chronic pain. Here, we review the exciting advances in thermoTRP pharmacology for males and females in two paradigmatic types of chronic pain with a strong peripheral component: chronic migraine and chemotherapy-induced peripheral neuropathy (CIPN). The possibilities of peripheral druggability offered by these channels and the differential exploitation for men and women represent a development opportunity that will lead to a significant increment of the armamentarium of analgesic medicines for personalized chronic pain treatment.
慢性疼痛是社会的主要负担,在女性中更为普遍和严重。慢性疼痛的存在与外周和中枢神经系统的持续改变有关。外周疼痛传感器的主要类型之一是瞬时受体电位通道(TRP),也称为热 TRP 通道,它们参与对外界冷热刺激的感知。由于这些通道(尤其是 TRPV1、TRPA1 和 TRPM8)作为热感受器的作用及其在急性和慢性疼痛中的作用,它们已经受到了深入的研究。令人惊讶的是,它们对内源性信号的敏感性的研究要少得多。越来越多的证据表明,这些通道的功能在男性和女性中的调节可能不同,部分原因是性激素的作用,这可能是慢性疼痛中性别差异的一个重要原因。在这里,我们回顾了在两种具有强烈外周成分的慢性疼痛的男性和女性的热 TRP 药理学方面的令人兴奋的进展:慢性偏头痛和化疗诱导的周围神经病变(CIPN)。这些通道提供的外周药物治疗可能性以及对男性和女性的不同利用代表了一个发展机会,将导致用于个性化慢性疼痛治疗的镇痛药物的储备显著增加。
