One of the most promising therapeutic targets for potential diseasemodifying treatment of Parkinson’s disease (PD) is leucine-rich repeat kinase 2 (LRRK2). Specifically, targeting LRRK2’s kinase function has generated a lot of interest from both industry and academia. This work has yielded several published studies showing the feasibility of developing potent, selective and brain permeable LRRK2 kinase inhibitors. The availa Read More

Alpha-Synuclein is found in the neuronal cells but its native function is not well known. While α -synuclein is an intrinsically disordered protein that adopts a helical conformation upon membrane binding, numerous studies have shown that oligomeric β-forms of this protein are cytotoxic. This response to misfolded species contributes to Parkinson’s Disease etiology and symptoms. The resulting amyloid fibrils are an established Read More

Autophagy is a cellular quality control mechanism crucial for neuronal homeostasis. Defects in autophagy are critically associated with mechanisms underlying Parkinson´s disease (PD), a common and debilitating neurodegenerative disorder. Autophagic dysfunction in PD can occur at several stages of the autophagy/lysosomal degradative machinery, contributing to the formation of intracellular protein aggregates and eventu Read More

Parkinson’s Disease (PD) related genes PINK1, a protein kinase [1], and Parkin, an E3 ubiquitin ligase [2], operate within the same pathway [3-5], which controls, via specific elimination of dysfunctional mitochondria, the quality of the organelle network [6]. Parkin translocates to impaired mitochondria and drives their elimination via autophagy, a process known as mitophagy [6]. PINK1 regulates Parkin translocation throug Read More

Parkinson’s disease (PD) is a degenerative neurological syndrome, which is characterized by the preferential death of dopaminergic (DAergic) neurons in the Substantia Nigra. The pathogenesis of this disorder remains poorly understood and PD is still incurable. Current drug treatments are aimed primarily for the treatment of symptoms to improve the quality of life. Therefore, there is a need to find out new therapeutic stra Read More

Although methylphenidate has been used as a neurostimulant to treat patients with attention deficit hyperactivity disorder, its therapeutic role in the psychomotor or cognitive recovery of patients with traumatic brain injuries (TBIs) in both intensive care and rehabilitation settings has not been adequately explored. To address this issue, this meta-analysis searched the available electronic databases using the key words “methylp Read More

Abstract: Selenium (34Se), an antioxidant trace element, is an important regulator of brain function. These beneficial properties that Se possesses are attributed to its ability to be incorporated into selenoproteins as an amino acid. Several selenoproteins are expressed in the brain, in which some of them, e.g. glutathione peroxidases (GPxs), thioredoxin reductases (TrxRs) or selenoprotein P (SelP), are strongly involved in anti Read More
