疼痛感知已经发展成为一种警告机制,以提醒生物体注意组织损伤和危险环境。然而,在人类中,不期望的、过度的或慢性的疼痛是一种常见的和主要的社会负担,对于这种负担,现有的医学治疗目前是次优的。新的治疗选择最近已经从对先天性疼痛不敏感(CIP)个体的研究中得出。在此,我们在来自11个家族的CIP受试者中鉴定了PRDM 12(编码PRDI-BF 1和含RIZ同源结构域的蛋白12)中的10种不同的纯合突变。Prdm蛋白是一个家族的表观遗传调控,控制神经规范和神经发生。我们确定Prdm 12在伤害感受器及其祖细胞中表达,并参与爪蟾胚胎感觉神经元的发育。此外,CIP相关突变体废除了与野生型Prdm 12相关的组蛋白修饰潜力。prdm 12作为感觉神经发生的关键因素出现,并可能成为新疼痛治疗的靶点。
Pain perception has evolved as a warning mechanism to alert organisms to tissue damage and dangerous environments. In humans, however, undesirable, excessive or chronic pain is a common and major societal burden for which available medical treatments are currently suboptimal. New therapeutic options have recently been derived from studies of individuals with congenital insensitivity to pain (CIP). Here we identified 10 different homozygous mutations in PRDM12 (encoding PRDI-BF1 and RIZ homology domain-containing protein 12) in subjects with CIP from 11 families. Prdm proteins are a family of epigenetic regulators that control neural specification and neurogenesis. We determined that Prdm12 is expressed in nociceptors and their progenitors and participates in the development of sensory neurons in Xenopus embryos. Moreover, CIP-associated mutants abrogate the histone-modifying potential associated with wild-type Prdm12. Prdm12 emerges as a key factor in the orchestration of sensory neurogenesis and may hold promise as a target for new pain therapeutics.
