СЕРДЦЕ И ВОЗРАСТ (ЧАСТЬ I): ТЕОРИИ СТАРЕНИЯ, МОРФОЛОГИЧЕСКИЕ ИЗМЕНЕНИЯ
Старение сердца — сложный процесс, включающий множество клеточных и молекулярных изменений на клеточном и молекулярном уровнях и приводящих к формированию разных фенотипов старения внутри одного вида. Согласно теориям старения на молекулярно-генетическом уровне взаимодействуют несколько механизмов, включая соматические мутации, укорочение теломер, окислительный стресс и дефекты митохондрий. Наиболее признанные на сегодня теории старения, а также морфологические признаки старения сердца на клеточном, субклеточном и органном уровнях представлены в этой статье.
