Abstract

Hyperpolarisation-activated cyclic nucleotide-gated (HCN) channels control neuronal firing thresholds. Together with sodium channels, they accumulate at sites of nerve injury, creating ectopic foci of action potential generation (EFAPG) that result in neuropathic pain.Their presence may explain why EFAPG do not always respond to sodium channel blockers (eg, lacosamide). Further, several current analgesics (clonidine, dexmedetomidine, ketamine and systemic lidocaine) block HCN channels in addition to their better-known actions. Future research could explore the use of ivabradine (an HCN blocker) and multichannel blockade for refractory EFAPG and develop tools to distinguish EFAPG from secondary 'upstream' pain mechanisms (eg, central sensitisation).

HCN通道:治疗周围神经性疼痛的新靶点。
超极化激活环核苷酸门控(HCN)通道控制神经元放电阈值。它们与钠离子通道一起积聚在神经损伤部位,形成动作电位产生异位灶(EFAPG),导致神经性疼痛。它们的存在可以解释为什么EFAPG并不总是对钠通道阻滞剂(如拉可沙胺)有反应。此外,几种现有的镇痛药(可乐定、右美托咪定、氯胺酮和全身利多卡因)除了它们众所周知的作用外,还能阻断HCN通道。未来的研究可以探索使用伊伐布雷定(一种HCN阻滞剂)和多通道阻断治疗难治性EFAPG,并开发工具来区分EFAPG与继发性“上游”疼痛机制(如中枢致敏)。

期刊介绍: Published quarterly in print and continuously online, BMJ Supportive & Palliative Care aims to connect many disciplines and specialties throughout the world by providing high quality, clinically relevant research, reviews, comment, information and news of international importance. We hold an inclusive view of supportive and palliative care research and we are able to call on expertise to critique the whole range of methodologies within the subject, including those working in transitional research, clinical trials, epidemiology, behavioural sciences, ethics and health service research. Articles with relevance to clinical practice and clinical service development will be considered for publication. In an international context, many different categories of clinician and healthcare workers do clinical work associated with palliative medicine, specialist or generalist palliative care, supportive care, psychosocial-oncology and end of life care. We wish to engage many specialties, not only those traditionally associated with supportive and palliative care. We hope to extend the readership to doctors, nurses, other healthcare workers and researchers in medical and surgical specialties, including but not limited to cardiology, gastroenterology, geriatrics, neurology, oncology, paediatrics, primary care, psychiatry, psychology, renal medicine, respiratory medicine.
