Abstract
Parkinson’s Disease (PD) is one of the most prevalent, recurrent and life-threatening neurodegenerative diseases. However, the precise mechanism underlying this disease is not yet clearly understood. For understanding the pathogenesis of PD, it is essential to identify the symptoms along with the novel biological markers and to develop strategies that could lead towards the development of effective therapy. PD is associated with Lewy bodies (LBs) formation and the loss of dopaminergic neurons in the substantia nigra pars compacta of mid brain region. For the improvement in treatment strategies, as well as understanding the pathophysiology of the PD in a number of animal models have been introduced that can recapitulate the pathophysiology, motor and nonmotor symptoms of PD. In contrast to mammalian models like rodents, mice and monkey, Drosophila is easy to handle as well as its maintenance cost is low. Due to the anatomical differences in the brain and other major organs of human and fly, the issues of standardizing the methods or experiments to analyze behavioral aspects (walking, writhing, eating and sleeping) are difficult in flies. The present review highlights the studies carried out for PD since 2000, using Drosophila melanogaster.
Keywords: Parkinson's disease, Drosophila melanogaster, lewy bodies, neurodegenerative disease, neurons, brain.

Lifestyle Interventions to Prevent and Treat Cognitive Impairment and Dementia
More than 55 million people live with dementia worldwide. By 2050, the population affected by dementia will exceed 139 million individuals. Mild cognitive impairment (MCI) is a pre-dementia stage, also known as prodromal dementia, affecting older adults. MCI emerges years before the manifestation of dementia but can be avoidable and ...read more

Role of glial cells in autism spectrum disorder: Molecular mechanism and therapeutic approaches
Emerging evidence suggests that glial cells may play a pivotal role in neuroanatomical and behavioral changes found in autism spectrum disorder (ASD). Many individuals with ASD experience neuro-immune system abnormalities throughout life, which implicates the potential role of microglia in the pathogenesis of ASD. Dysfunctional astrocytes and oligodendrocytes have been ...read more
