In the aging communities, wound healing management is a quite remarkable problem especially in elderly individuals. The optimal level of healing of wounds developed spontaneously or due to surgery is of critical importance in order to prevent the negative effects that may occur due to delayed healing (for example, organ or system damage caused by infections that may develop in the wound area). The deteriorated subcellular redox signaling is considered to be as the main factor in the chronicity of wounds. The pivotal role of mitochondria in redox regulation reveals the importance of modulation of redox signaling pathways in senescent cells. Secretory factors released upon the acquisition of senescence-associated secretory phenotype (SASP) function in a paracrine manner to disseminate impaired tissue redox status by affecting the redox metabolome of nearby cells, which could promote age-related pro-inflammatory pathologies. Evaluating the wound-site redox regulation in impaired redox signaling pathways may help prevent the formation of chronic wounds and the development of long-term complications of the wounds, especially in the elderly. Using the redox modulatory pharmacologically active substances targeting the senescent cells in chronic wound areas hopefully opens a new avenue in wound management. As the signaling mechanisms of wound healing and its relationship with advanced age become more clearly understood, many promising therapeutic approaches and redox modulator substances are coming into clinical view for the management of chronic wounds.
在老龄化社区中,伤口愈合管理是一个非常突出的问题,尤其是在老年人中。为了防止因愈合延迟而产生的负面影响(例如,伤口区域可能发生的感染导致的器官或系统损伤),自发或因手术而产生的伤口的最佳愈合水平至关重要。细胞亚结构的恶化氧化还原信号被认为是伤口慢性化的主要因素。线粒体在氧化还原调节中的关键作用揭示了调节衰老细胞中氧化还原信号通路的重要性。获得衰老相关分泌表型(SASP)后释放的分泌因子以旁分泌的方式发挥作用,通过影响附近细胞的氧化还原代谢组来传播受损的组织氧化还原状态,从而促进与年龄相关的促炎病理。评估受损氧化还原信号通路中的伤口部位氧化还原调节有助于防止慢性伤口的形成和伤口的长期并发症,特别是在老年人中。使用针对慢性伤口区域衰老细胞的氧化还原调节药理活性物质,有望为伤口管理开辟新途径。随着对伤口愈合的信号机制及其与年龄增长的关系的理解更加清楚,许多有前途的治疗方法和氧化还原调节剂正在进入临床视野,用于慢性伤口的管理。
