创伤事件会产生一些最持久的记忆形式。尽管焦虑症的终生患病率上升,但减轻长期创伤记忆的有效策略很少。减少新近(即一天前的)创伤的最有效的治疗方法是利用记忆回忆启动的再巩固过程中的记忆更新机制。在这里,我们表明,在小鼠中,成功的最近记忆的重新巩固-更新范例未能削弱遥远的(即,一个月前的)记忆。我们发现,虽然最近的记忆回忆诱导了一段有限的海马神经可塑性,部分是由HDAC2的S亚硝化和组蛋白乙酰化介导的,但这种可塑性在远距离记忆中是不存在的。然而,通过在再巩固过程中使用HDAC2靶向抑制剂(HDACi),即使是远程记忆也可以被持久地减弱。这种干预在表观遗传学上启动了神经可塑性相关基因的表达,伴随着更高的代谢、突触和结构可塑性。因此,在记忆再巩固期间应用HDACis可能是治疗远程创伤的一种选择。
Traumatic events generate some of the most enduring forms of memories. Despite the elevated lifetime prevalence of anxiety disorders, effective strategies to attenuate long-term traumatic memories are scarce. The most efficacious treatments to diminish recent (i.e., day-old) traumata capitalize on memory updating mechanisms during reconsolidation that are initiated upon memory recall. Here, we show that, in mice, successful reconsolidation-updating paradigms for recent memories fail to attenuate remote (i.e., month-old) ones. We find that, whereas recent memory recall induces a limited period of hippocampal neuroplasticity mediated, in part, by S-nitrosylation of HDAC2 and histone acetylation, such plasticity is absent for remote memories. However, by using an HDAC2-targeting inhibitor (HDACi) during reconsolidation, even remote memories can be persistently attenuated. This intervention epigenetically primes the expression of neuroplasticity-related genes, which is accompanied by higher metabolic, synaptic, and structural plasticity. Thus, applying HDACis during memory reconsolidation might constitute a treatment option for remote traumata.
