Abstract

The slow accumulation of inflammatory biomarker levels in the body-also known as inflammaging-has been linked to a myriad of age-related diseases. Some of these include neurodegenerative conditions such as Parkinson's disease, obesity, type II diabetes, cardiovascular disease, and many others. Though a direct correlation has not been established, research connecting age-related hearing loss (ARHL)-the number one communication disorder and one of the most prevalent neurodegenerative diseases of our aged population-and inflammaging has gained interest. Research, thus far, has found that inflammatory markers, such as IL-6 and white blood cells, are associated with ARHL in humans and animals. Moreover, studies investigating ion channels and mitochondrial involvement have shown promising relationships between their functions and inflammaging in the cochlea. In this review, we summarize key findings in inflammaging within the auditory system, the involvement of ion channels and mitochondrial functions, and lastly discuss potential treatment options focusing on controlling inflammation as we age.

摘要

体内炎症生物标志物水平的缓慢积累——也称为炎症衰老——与许多与年龄相关的疾病有关。其中一些包括神经退行性疾病,如帕金森病、肥胖症、2 型糖尿病、心血管疾病等。虽然尚未建立直接相关性,但将与年龄相关的听力损失(ARHL)——头号交流障碍和我们老年人群中最常见的神经退行性疾病之一——与炎症衰老联系起来的研究引起了人们的兴趣。迄今为止的研究发现,炎症标志物,如 IL-6 和白细胞,与人类和动物的 ARHL 有关。此外,研究离子通道和线粒体参与的研究表明,它们的功能与耳蜗中的炎症衰老之间存在有希望的关系。在这篇综述中,我们总结了听觉系统中炎症衰老、离子通道和线粒体功能的关键发现,并最后讨论了潜在的治疗选择,重点是控制衰老过程中的炎症。
