Within the span of few decades, there has been a significant increase in diabetes mellitus and chronic stress in developed countries, such as the Czech Republic. These conditions have a significant negative effect on physical and mental health. Repeated and long-term exposure to raised levels of glucose, overactivity of the sympathetic nervous system and the increase in plasma levels of stress hormones affects most of the organs in the body, including the heart. The cardiovascular system is regulated by a broad number of neurotransmitters, hormones and neuropeptides. Alterations in the innervation of the cardiovascular system, as a result of both diseases, can affect its physiological functions. The present thesis focuses not only on the role of the classic, but primarily on the peptidergic innervation of the heart. The aim was to contribute to the explanation of the impact of neuropeptides and their shared receptor systems on the genesis and the development of heart damage due to diabetes mellitus and/or exposure to stressors. Knowledge of the physiological characteristics of neuropeptides and their involvement in the pathogenesis of both diseases and related complications could be helpful in determining the optimal treatment method or alternatively allow us to use the cardio protective effect of... |
