Abstract

Chronic wounds are considered a silent epidemic that impact millions of human lives worldwide, causing comorbidities, reducing life quality and expectancy. Diabetic, pressure, and venous ulcers are the three major clinical entities of chronic wounds, in which the presence of a chronicity phenotype and episodes of recurrence remain as contemporary challenges. We are, accordingly, far from a full understanding about the potential endogenous, predisposing factors that may drive both chronicity and recurrence. Decades of academic and financial endeavors have not translated into a pharmacological intervention that may curb these events. These wounds may exhibit the clinical aspect of a torpid granulative response, poor angiogenesis, delayed or abnormal re-epithelialization, and low contraction rates. At the cellular level, chronicity is propelled and distinguished by the triad of interplaying loops of inflammation, oxidative stress, and cellular senescence. Although the proximal molecular drivers of chronicity and their hierarchal debut sequence are a critical research target and pending task, our unifying hypothesis behind chronicity and recurrence is founded on the existence of an epigenetic pathologic code that originates and perpetuates a "chronic wound memory". In vitro studies suggest that this edited script is sheltered in dermal fibroblasts and keratinocytes and is spreadable and transmissible to descendant cells, dictating abnormal traits even in ideal culture conditions and successive passages. The list of epigenomic alterations and their significance in wound pathology is continuously escalating. The accurate identification of the key epigenetic priming codes of impaired healing, and their selective re-editing, will be remarkably beneficial.

摘要

慢性伤口被视为一种无声的流行病,影响着全球数百万人的生活,会引发合并症,降低生活质量和预期寿命。糖尿病性溃疡、压疮和静脉溃疡是慢性伤口的三大主要临床类型,其中慢性表型的存在和复发情况仍是当今面临的挑战。因此,我们远未完全了解可能导致慢性化和复发的潜在内源性易感因素。数十年的学术和资金投入尚未转化为能够抑制这些情况的药物干预措施。这些伤口可能表现出迟缓的肉芽反应、血管生成不良、上皮再形成延迟或异常以及收缩率低等临床特征。在细胞水平上,慢性化由炎症、氧化应激和细胞衰老相互作用的三重循环推动并得以区分。尽管慢性化的近端分子驱动因素及其层次首次出现顺序是一个关键的研究目标和有待完成的任务,但我们关于慢性化和复发的统一假说是基于一种表观遗传病理编码的存在,这种编码产生并延续“慢性伤口记忆”。体外研究表明,这个编辑后的脚本存在于真皮成纤维细胞和角质形成细胞中,可传播并传递给后代细胞,即使在理想的培养条件和连续传代过程中也会决定异常特征。表观基因组改变及其在伤口病理学中的意义的清单在不断增加。准确识别愈合受损的关键表观遗传启动编码并对其进行选择性重新编辑将非常有益。
