Abstract | INTRODUCTION: The upregulation of Nav1.8 in primary afferents plays a critical role in the development and persistence of neuropathic pain. The mechanisms underlying the upregulation are not fully understood. AIMS: The present study aims to investigate the regulatory effect of histamine on the expression of Nav1.8 in primary afferent neurons and its involvement in neuropathic pain. RESULTS: CONCLUSIONS: Our findings indicate that histamine increases Nav1.8 expression in primary afferent neurons via H2 receptor-mediated pathway and thereby contributes to neuropathic pain. H2 receptor antagonists may potentially be used as analgesics for patients with neuropathic pain.
