Aim: The effect of Majun Falasfa (MF) was studied on the transgenic Drosophila expressing human alpha synuclein panneurally. Background: MF is a Unani medicine used for enhancing mental power and treating kidney, joint pains and urinary tract diseases. It is also use for phlegmatic diseases. It is also being used in age related dementia and to counter the effects of ageing. Methods: The equivalents of recommended dose for human were established for 20g of fly food i.e. 0.0014, 0.0028, 0.0042 and 0.0056g per 20g of diet. The PD flies were allowed to feed on it for 24 days before studying its effect on cognitive and oxidative stress parameters. Immunohistochemistry was also performed study the effect of MF on human alpha synuclein expression. Results: The exposure to MF increased the life span and improves the activity of PD flies. MF delayed the loss of climbing ability of PD flies. The exposure of PD flies to MF significantly reduced the oxidative stress and improves the antioxidant enzymes homeostasis compared to unexposed PD flies. The exposure to MF reduces the formation of Lewy bodies as is evident by immunohistochemistry. Conclusion: MF is potent in reducing the PD (Parkinson’s disease) symptoms being mimicked in the transgenic flies.

Background: Parkinson’s Disease (PD) is characterized by the aggregation of α-synuclein, formation of Lewy bodies and the selective loss of dopaminergic neurons of mesencephalic substantia nigra pars compacta (SNC) with the debilitating motor symptoms. Introduction: The available treatment for PD provides symptomatic relief with no control on the progression of the disease. The treatment is also associated with several side effects. As the neurodegeneration in PD is also associated with the oxidative stress, antioxidants from plants could play an important role in reducing the PD symptoms. With this aim we decided to study the effect of Lemon grass extract (LGE) on the transgenic Drosophila model of PD expressing human alpha synuclein in the neurons. Methods: The PD flies allowed were allowed to feed on different doses of LGE established in diet for 24 days and then assayed for climbing ability and oxidative stress markers. The molecular docking study was also performed for citral (the component of the extract) and human α-synuclein. Results and discussion: A dose dependent significant improvement in the climbing ability and reduction in oxidative stress was observed in the PD flies exposed to LGE. In our earlier study on LGE, citral was found to be the main component of the extract by GC-MS analysis. The docking results also support the positive interaction between citral and human α-synuclein. Conclusion: The results suggests that LGE is potemnt in reducing the PD symptoms being mimicked in transgenic Drosophila.

The Brain

The genetic models in Drosophila provide a platform to understand the mechanism associated with degenerative diseases. The model for Parkinson's disease (PD) based on normal human alpha-synuclein (αS) expression was used in the present study. The aggregation of αS in brain leads to the formation of Lewy bodies and selective loss of dopaminergic neurons due to oxidative stress. Polyphenols generally have the reduced oral bioavailability, increased metabolic turnover, and lower permeability through the blood brain barrier. In the present study, the effect of synthesized alginate-curcumin nanocomposite was studied on the climbing ability of the PD model flies, lipid peroxidation, and apoptosis in the brain of PD model flies. The alginate-curcumin nanocomposite at final doses of 10−5, 10−3, and 10−1 g/mL was supplemented with diet, and the flies were allowed to feed for 24 days. A significant dose-dependent delay in the loss of climbing ability and reduction in the oxidative stress and apoptosis in the brain of PD model flies were observed. The results suggest that alginate-curcumin nanocomposite is potent in delaying the climbing disability of PD model flies and also reduced the oxidative stress as well as apoptosis in the brain of PD model flies.

Background: Parkinson’s disease is a common neurodegenerative disorder characterized by selective loss of dopaminergic neurons in the substantia nigra pars compacta. Introduction: The effects of alpha synuclein, parkin mutation and pharmacological agents have been studied in the Drosophila model. Methods: The effect of cabergoline was studied on the cognitive impairments exhibited by the transgenic Drosophila expressing human alpha-synuclein in the neurons. The PD flies were allowed to feed on the diet having 0.5, 1 and 1.5 μM of cabergoline. Results and Discussion: The exposure of cabergoline not only showed a dose-dependent significant delay in the cognitive impairments but also prevented the loss of dopaminergic neurons. Molecular docking studies showed the positive interaction between cabergoline and alpha-synuclein. Conclusion: The results suggest a protective effect of cabergoline against the cognitive impairments.

Park Genes

Parkinson’s disease (PD) is an age-related neurodegenerative disorder affecting millions of people worldwide. The disease is characterized by the progressive loss of dopaminergic neurons and spread of Lewy pathology (α-synuclein aggregates) in the brain but the pathogenesis remains elusive. PD presents substantial clinical and genetic variability. Although its complex etiology and pathogenesis has hampered the breakthrough in targeting disease modification, recent genetic tools advanced our approaches. As such, mitochondrial dysfunction has been identified as a major pathogenic hub for both familial and sporadic PD. In this review, we summarize the effect of mutations in 11 PARK genes (SNCA, PRKN, PINK1, DJ-1, LRRK2, ATP13A2, PLA2G6, FBXO7, VPS35, CHCHD2, and VPS13C) on mitochondrial function as well as their relevance in the formation of Lewy pathology. Overall, these genes play key roles in mitochondrial homeostatic control (biogenesis and mitophagy) and functions (e.g., energy production and oxidative stress), which may crosstalk with the autophagy pathway, induce proinflammatory immune responses, and increase oxidative stress that facilitate the aggregation of α-synuclein. Thus, rectifying mitochondrial dysregulation represents a promising therapeutic approach for neuroprotection in PD.

Pathologic Features

Parkinson’s disease is the most common age-related motor movement disorder. Pathological changes in Parkinson’s disease are the loss of melanin-containing dopaminergic neurons and the detection of inclusion bodies in the cells, which contain alpha-synuclein and ubiquitinated proteins, called as Lewy bodies. In this review; the structure of Lewy bodies, structural features and intracellular localization of α-synuclein protein, intracellular functions and intercellular spread of α-synuclein protein are discussed. The physiological and pathologic features of α-synuclein protein are reviewed based mostly upon review of the literature. α-synuclein has significant functions especially at central nervous system. α-synuclein is a protein that can be found in various areas within the cell, particularly in the presynaptic axon terminals. Under pathologic conditions, cellular accumulation of misfolded α-synuclein oligomers and aggregates are observed in a group of neurodegenerative diseases called synucleinopathies. The mechanisms of how α-synuclein protein takes part in the neurodegeneration process and physiologic roles of the protein have not been fully elucidated yet. It’s important to unravel the secrets of this protein and understand its behaviours in order to improve existing treatment protocols and also to develop new and more effective treatments for Parkinson’s Disease.
