Inflammatory mediators may reflect a role of systemic inflammation in the neurodegenerative process of Parkinson’s disease (PD). Interleukin-6 (IL-6) and chemokine ligand 5 (CCL5), also known as RANTES (regulated on activation, normal T cell expressed and secreted), have been implicated in neurodegenerative diseases including PD. Serum levels of RANTES and IL-6 of 78 consecutive PD patients and age-matched 80 controls were measured. Patients with PD had higher RANTES and IL-6 levels compared with the controls. We found that serum RANTES levels strongly correlated with Hoehn-Yahr score and disease duration in PD patients. This study indicated that patients with PD have an on-going systemic inflammatory profile where the elevated peripheral production of RANTES may play a role in the neurodegenerative process.

:Parkinson’s disease (PD) is the second most common neurodegenerative disorder among elderly population, characterized by the progressive degeneration of dopaminergic neurons in the midbrain. To date, exact cause remains unknown and the mechanism of neurons death uncertain. It is typically considered as a disease of central nervous system (CNS). Nevertheless, numerous evidence has been accumulated in several past years testifying undoubtedly about the principal role of neuroinflammation in progression of PD. Neuroinflammation is mainly associated with presence of activated microglia in brain and elevated levels of cytokine levels in CNS. Nevertheless, active participation of immune system as well has been noted, such as, elevated levels of cytokine levels in blood, the presence of auto antibodies, and the infiltration of T cell in CNS. Moreover, infiltration and reactivation of those T cells could exacerbate neuroinflammation to greater neurotoxic levels. Hence, peripheral inflammation is able to prime microglia into pro-inflammatory phenotype, which can trigger stronger response in CNS further perpetuating the on-going neurodegenerative process.:In the present review, the interplay between neuroinflammation and the peripheral immune response in the pathobiology of PD will be discussed. First of all, an overview of regulation of microglial activation and neuroinflammation is summarized and discussed. Afterwards, we try to collectively analyze changes that occurs in peripheral immune system of PD patients, suggesting that these peripheral immune challenges can exacerbate the process of neuroinflammation and hence the symptoms of the disease. In the end, we summarize some of proposed immunotherapies for treatment of PD.

Neuroinflammation is a crucial process associated with the pathogenesis of neurodegenerative diseases, including Parkinson’s disease (PD). Several pieces of evidence suggest an active role of lipid mediators, especially epoxy-fatty acids (EpFAs), in the genesis and control of neuroinflammation; 14,15-epoxyeicosatrienoic acid (14,15-EET) is one of the most commonly studied EpFAs, with anti-inflammatory properties. Soluble epoxide hydrolase (sEH) is implicated in the hydrolysis of 14,15-EET to its corresponding diol, which lacks anti-inflammatory properties. Preventing EET degradation thus increases its concentration in the brain through sEH inhibition, which represents a novel pharmacological approach to foster the reduction of neuroinflammation and by end neurodegeneration. Recently, it has been shown that sEH levels increase in brains of PD patients. Moreover, the pharmacological inhibition of the hydrolase domain of the enzyme or the use of sEH knockout mice reduced the deleterious effect of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) administration. This paper overviews the knowledge of sEH and EETs in PD and the importance of blocking its hydrolytic activity, degrading EETs in PD physiopathology. We focus on imperative neuroinflammation participation in the neurodegenerative process in PD and the putative therapeutic role for sEH inhibitors. In this review, we also describe highlights in the general knowledge of the role of sEH in the central nervous system (CNS) and its participation in neurodegeneration. We conclude that sEH is one of the most promising therapeutic strategies for PD and other neurodegenerative diseases with chronic inflammation process, providing new insights into the crucial role of sEH in PD pathophysiology as well as a singular opportunity for drug development.

Abstract: Introduction: Selective monoamine oxidase B inhibitors have an accurate place in therapeutical strategy of Parkinsons’s disease. In the early stages of the disease, especially in younger patients with milder symptoms, the introduction of levodopa substitution could be efficacious in delaying; in advanced stages they are mainly used to treat motor complications, as an adjunct to levodopa. Aim: The evaluation of therapeutical strategies used in the neurology clinics of Tirgu Mures County Emergency Clinical Hospital in order to define the role of monoamine oxidase B inhibitors. Method: This retrospective study includes all records of patients with Parkinson’s disease hospitalized between 1 January 2003 and 31 December 2016. From the 2194 reports we used data focusing on the therapeutic recommendations. Regarding disease duration, we divided the patients in two groups: less than or equal to 5 years and more than 5 years. Results: From the 1183 patients in first group, 243 received monoamine oxidase inhibitors: 12 as monotherapy, 52 together with dopamine agonists, in 61 cases combined with levodopa. In 118 cases monoamine oxidase inhibitors were combined with levodopa and dopamine agonists. From 582 cases whith Parkinson’s disease for more than 5 years, 195 received monoamine oxidase B inhibitors (selegiline: 10 cases, rasagiline: 185 cases). In 429 cases we did not find accurate data regarding disease duration (selegiline: 5 cases, rasagiline: 93 cases). Conclusion: The use of monoamine oxidase B inhibitors was similar to those found in literature. The treating physicians should utilise more confidently the available therapeutical combinations.

Abstract The pathogenetic aspects of Parkinson's disease and possible ways of their correction. Buchakchyiska N. M., Maramukha V. I., Maramukha I. V. Purpose of the study. The purpose of the work is to summarize the data available in the literature regarding the role of shock proteins, in particular the HSP 70 protein, in the mechanisms of endogenous neuroprotection and neurodegradation in Parkinson's disease (PD). The article also aims at determining the possible pathogenetic stages of the disease development and the place of mitochondrial dysfunction, apoptotic and antiapoptotic systems in these processes. The modulation of PD MPTP model can help to identify possible ways of influencing the pathogenetic mechanisms of neurodegenerative changes in structures of the extrapyramidal system by stimulating the processes of neuroprotection and slowing of neurodegradation owing to inducing protein level synthesis. After statistical processing of the obtained results, one can interpolate the obtained data on idiopathic PD in the population by matching the relevant neurodegenerative process markers found in the experiment with indicators in PD patients. As a result, it may hypothetically be possible to develop the use of personalized pathogenetic therapy for PD. Keywords: Parkinson’s disease, neuroprotection, heat shock

Dopamine Oxidation

The molecular mechanisms involved in the neurodegenerative process of Parkinson's disease remain unclear. Currently, there is a general agreement that mitochondrial dysfunction,α-synuclein aggregation, oxidative stress, neuroinflammation, and impaired protein degradation are involved in the neurodegeneration of dopaminergic neurons containing neuromelanin in Parkinson's disease. Aminochrome has been proposed to play an essential role in the degeneration of dopaminergic neurons containing neuromelanin by inducing mitochondrial dysfunction, oxidative stress, the formation of neurotoxicα-synuclein protofibrils, and impaired protein degradation. Here, we discuss the relationship between the oxidation of dopamine to aminochrome, the precursor of neuromelanin, autophagy dysfunction in dopaminergic neurons containing neuromelanin, and the role of dopamine oxidation to aminochrome in autophagy dysfunction in dopaminergic neurons. Aminochrome induces the following: (i) the formation ofα-synuclein protofibrils that inactivate chaperone-mediated autophagy; (ii) the formation of adducts withα- andβ-tubulin, which induce the aggregation of the microtubules required for the fusion of autophagy vacuoles and lysosomes.

ABSTRACT Falls are common among persons with Parkinson's disease (PD). On the other hand, predicting falls is complex as there are both generic and PD-specific contributors. In particular, the role of non-motor symptoms has been less studied. Objective: The objective of this study was to identify the role of non-motor predictors of falling in persons with PD (PwP). Methods: A cross-sectional study was carried out in PwP recruited from a movement disorders clinic. Clinical and demographical data were collected. All PwP were assessed using the Movement Disorders Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS) and the Non-Motor Symptoms Scale (NMSS). Variables were assessed at the bivariate level. Significant variables were put into a logistic regression model. Results: A total of 179 PwP were included. Overall, 16.8% of PwP had fallen in the past 12 months, with 53.3% of them being recurrent fallers. The mean number of monthly falls was 2.5 ± 3.3. Factors associated with falling in the bivariate analysis included the disease duration, Hoehn and Yahr stage, MDS-UPDRS part I and II, postural instability/gait disturbance (PIGD) subtype, NMSS urinary domain, NMSS miscellaneous domain, and non-motor severity burden (all p-values < 0.05). After multivariate analysis, only the disease duration (p = 0.03) and PIGD (p = 0.03) remained as independent risk factors. Conclusion: Disease duration and the PIGD subtype were identified as relevant risk factors for falls in PwP Non-motor symptoms appear to have a less important role as risk factors for falls.
