The past few decades have seen an increased emphasis on the involvement of the mitochondrial-associated membrane (MAM) in various neurodegenerative diseases, particularly in Parkinson’s disease (PD) and Alzheimer’s disease (AD). In PD, alterations in mitochondria, endoplasmic reticulum (ER), and MAM functions affect the secretion and metabolism of proteins, causing an imbalance in calcium homeostasis and oxidative stress. These changes lead to alterations in the translocation of the MAM components, such as IP3R, VDAC, and MFN1 and 2, and consequently disrupt calcium homeostasis and cause misfolded proteins with impaired autophagy, distorted mitochondrial dynamics, and cell death. Various reports indicate the detrimental involvement of the brain renin–angiotensin system (RAS) in oxidative stress, neuroinflammation, and apoptosis in various neurodegenerative diseases. In this review, we attempted to update the reports (using various search engines, such as PubMed, SCOPUS, Elsevier, and Springer Nature) demonstrating the pathogenic interactions between the various proteins present in mitochondria, ER, and MAM with respect to Parkinson’s disease. We also made an attempt to speculate the possible involvement of RAS and its components, i.e., AT1 and AT2 receptors, angiotensinogen, in this crosstalk and PD pathology. The review also collates and provides updated information on the role of MAM in calcium signaling, oxidative stress, neuroinflammation, and apoptosis in PD.

Введение. В настоящее время в научной литературе имеется большой объем данных, посвященных болезни Паркинсона. В то же время недостаточно освещена роль ренин-ангиотензиновой системы (РАС) в патогенезе заболевания. Цель - оценка современных патогенетически обоснованных подходов к терапии болезни Паркинсона. Методика. В базах данных Medline (PubMed) и eLibrary осуществлен подбор и анализ современных источников литературы, посвященных изучению роли ренин-ангиотензиновой системы в патогенезе болезни Паркинсона. Результаты. Болезнь Паркинсона является хроническим нейродегенеративным заболеванием, которое проявляется моторными и немоторными нарушениями. Анализ литературы показал, что помимо системной ренин-ангиотензиновой системы во многих тканях и органах имеется локальная РАС. Авторами было показано, что дофамин и ангиотензин II взаимодействуют в черной субстанции (SN) и стриатуме в реципрокном отношении. В модельных экспериментах на животных доказано, что снижение уровней дофамина сопровождается гиперактивацией ренин-ангиотензиновой системы. При этом так же отмечается выброс активных форм кислорода, индуцируемый микроглиальной тканью, и развитие нейровоспаления, что сопровождается нейродегенерацией. Применение блокаторов ангиотензиновых рецепторов в моделях на животных и в клинических испытаниях позволило значительно снизить прогрессирование нейродегенерации черной субстанции. Заключение. Авторами изложены результаты, свидетельствующие о том, что развитие болезни Паркинсона сопровождается гиперактивацией мозговой РАС. Подразумевается, что на новое звено патогенеза можно терапевтически воздействовать. Необходимы дополнительные исследования для понимания механизмов данных процессов. Background. A large amount of literature on Parkinson’s disease is currently available. However, the role of the renin-angiotensin system in the pathogenesis of this disease is not sufficiently covered. Aim. To highlight new therapeutic possibilities based on pathophysiological mechanisms of Parkinson’s disease. Methods. The literature retrieved from the PubMed, Medline, and eLibrary databases focusing on the role of the renin-angiotensin system in the pathogenesis of Parkinson’s disease was analyzed. Results. Parkinson’s disease (PD) is a chronic neurodegenerative disease associated with persistent neurological disorders. Studies have demonstrated that a local renin-angiotensin system (RAS) exists in many tissues and organs along with the systemic RAS. The authors showed that dopamine and angiotensin II interact reciprocally in the substantia nigra (SN) and striatum. In animal models, a decrease in the dopamine level was accompanied by RAS overactivation. Furthermore, microglial tissue induced production of reactive oxygen species, which was associated with neuroinflammation. The angiotensin receptor blocker treatment used in animal models and clinical trials significantly reduced the progression of SN neurodegeneration. Conclusions. The authors reviewed the data of literature demonstrating that the progression of Parkinson’s disease is associated with overactivation of the cerebral RAS. Apparently, it is possible to influence therapeutically this new pathogenetic component of Parkinson’s disease. Further study is required for understanding the mechanisms of this process.

Cerebrovascular Diseases (CVD) comprise a wide spectrum of disorders, all sharing an acquired or inherited alteration of the cerebral vasculature. CVD have been associated with important changes in systemic and tissue Renin-Angiotensin System (RAS). The aim of this review was to summarize and to discuss recent findings related to the modulation of RAS components in CVD. The role of RAS axes is more extensively studied in experimentally induced stroke. By means of AT1 receptors in the brain, Ang II hampers cerebral blood flow and causes tissue ischemia, inflammation, oxidative stress, cell damage and apoptosis. On the other hand, Ang-(1-7) by stimulating Mas receptor promotes angiogenesis in brain tissue, decreases oxidative stress, neuroinflammation, and improves cognition, cerebral blood flow, neuronal survival, learning and memory. In regard to clinical studies, treatment with Angiotensin Converting Enzyme (ACE) inhibitors and AT1 receptor antagonists exerts preventive and therapeutic effects on stroke. Besides stroke, studies support a similar role of RAS molecules also in traumatic brain injury and cerebral aneurysm. The literature supports a beneficial role for the alternative RAS axis in CVD. Further studies are necessary to investigate the therapeutic potential of ACE2 activators and/or Mas receptor agonists in patients with CVD.

Abstract: The discovery of charged molecules being able to cross the mitochondrial membrane has prompted many scholars to exploit this idea to find a way of preventing or slowing down aging. In this paper, we will focus on mitochondriatargeted antioxidants, which are cationic derivatives of plastoquinone, and in particular on the mitochondria-targeted antioxidant therapy of neurodegenerative diseases. It is well known that the accumulation of amyloid-β peptide (Aβ) in mitochondria and its related mitochondrial dysfunction are critical signatures of Alzheimer’ s disease (AD). In another neurodegenerative disease, Parkinson’s disease (PD), the loss of dopaminergic neurons in the substantia nigra and the production of Lewy bodies are among their pathological features. Pathogenesis of Parkinson’s disease and Alzheimer’s disease has been frequently linked to mitochondrial dysfunction and oxidative stress. Recent studies show that MitoQ, a mitochondria-targeted antioxidant, may possess therapeutic potential for Aβ-related and oxidative stress-associated neurodegenerative diseases, especially AD. Although MitoQ has been developed to the stage of clinical trials in PD, its true clinical effect still need further verification. This review aims to discuss the role of mitochondrial pathology in neurodegenerative diseases, as well as the recent development of mitochondrial targeted antioxidants as a potential treatment for these diseases by removing excess oxygen free radicals and inhibiting lipid peroxidation in order to improve mitochondrial function.

Huntington’S Disease

Neurodegenerative diseases affect not only the life quality of aging populations, but also their life spans. All forms of neurodegenerative diseases have a massive impact on the elderly. The major threat of these brain diseases includes progressive loss of memory, Alzheimer’s disease (AD), impairments in the movement, Parkinson’s disease (PD), and the inability to walk, talk, and think, Huntington’s disease (HD). Oxidative stress and mitochondrial dysfunction are highlighted as a central feature of brain degenerative diseases. Oxidative stress, a condition that occurs due to imbalance in oxidant and antioxidant status, has been known to play a vital role in the pathophysiology of neurodegenerative diseases including AD, PD, and HD. A large number of studies have utilized oxidative stress biomarkers to investigate the severity of these neurodegenerative diseases and medications are available, but these only treat the symptoms. In traditional medicine, a large number of medicinal plants have been used to treat the symptoms of these neurodegenerative diseases. Extensive studies scientifically validated the beneficial effect of natural products against neurodegenerative diseases using suitable animal models. This short review focuses the role of oxidative stress in the pathogenesis of AD, PD, and HD and the protective efficacy of natural products against these diseases.

The Impact

Abstract Background Renin-angiotensin system (RAS) influences the central nervous system not only through its peripheral impact—the brain possesses its own local RAS. Studies showed altered RAS components in Parkinson’s disease (PD) and their association with oxidative stress which may be linked to neurodegeneration and dementia. Moreover, the protective functions of RAS blockade antagonists against cognitive decline and dementia have been suggested. This study aimed to examine whether genetic variability in RAS genes correlates with cognitive decline in PD. Methods and results We genotyped single nucleotide polymorphisms (SNPs) in angiotensinogen (AGT: rs699, rs4762), angiotensin II receptors (AGTR1: rs5186 and AGTR2: rs5194, rs1403543) genes, as well as insertion/deletion polymorphism in the angiotensin-converting enzyme (ACE I/D) gene in 256 PD patients, divided into three groups: without cognitive decline, with mild cognitive impairment and with PD dementia. We did not find any significant differences in the frequencies of the analysed polymorphisms in any of the groups. Conclusions Despite no direct correlation between the investigated polymorphisms in RAS genes and cognitive decline in PD, we believe the impact of those genotypes may be indirect, affecting RAS blockade treatment.
