Mohammed","doi":"10.23937/2643-4539/1710023","DOIUrl":"https://doi.org/10.23937/2643-4539/1710023","url":null,"abstract":"Down syndrome (DS) is the most frequent genetic disease characterized by several neuropathological features including alteration in neurogenesis, mental disability, cognitive impairments, learning-memory deficits and early onset of Alzheimer’s disease (AD). Over expression of chromosome 21 genes, localized in Down Syndrome Critical Region (DSCR), is the main cause of DS neuropathological features. We studied herein one of DSCR genes, DYRK1A (Dual-Specificity Tyrosine-Phosphorylation-Regulated Ki nase 1A), well-known Drosophila Mini-Brain gene, as a master regulator involved in DS neuropathological features and associated AD. DYRK1A is a central member of phosphorylation pathways regulating cell cycle and belongs to a family of Dual-Specificity Protein Kinases (DYRK kinases) playing key roles in central nervous system. DYRK1A regulates several transcriptional factors, such as CREB (cyclic-AMP response element-binding protein), NFAT (nuclear factor of activated T cells) and signaling pathways playing critical roles in brain functions. Significant associations were found between DYRK1A and regulation of cytoskeletal dynamics of actin, tubulin or microtubule-linked protein Tau, regulation of Tau phosphorylation, Amyloid Precursor Protein (APP) or Presenilin 1 (PS1), regulation of neurogenesis, synaptogenesis, and AD-like neurofibrillary tangles formation. Interestingly, normalization of DYRK1A overexpression by DYRK1A inhibitor, epigalloctechin-3-gallate (EGCG), rescues brain defects, restores cognitive impairments in DS trisomic and DYRK1A transgenic mouse models and DS patients,modulates Amyloid Precursor Protein (APP) cleavage and reduces cerebral amyloidosis in AD transgenic mouse models. DYRK1A inhibitors such as Har-mine, LeucettineL41, SM07883 successfully reduces Tau phosphorylation at multiple AD-related sites, rescues AD phenotypes in APP/PS1 mice and correct cognitive and memory deficits in AD animal models. These results indica tes DYRK1A inhibitors as effective treatments and identifies DYRK1A as a master regulatory protein involved in DS and AD neuropathological features suggestingDYRK1A as promising potential drug target for therapeutics and treatments of DS and AD.

Categorized as a synucleinopathy, the pathological hallmark of PD is intracellular filamentous Lewy bodies (LB), which are formed from protopathic aggregates. The most prevalent of these proteins is the presynaptic protein ɑ-synuclein (α-syn). While commonly attributed to neuronal death in SNpc, postmortem studies have shown α-syn immunoreactivity and LB pathology in the peripheral, central, and enteric nervous system (ENS). While the etiology of misfolded α-syn is unknown, various gut microbiota and substrates are associated with α-syn dysfunction. Gastrointestinal (GI) dysfunction, a common feature in the prodromal phase of PD patients, and histological evidence have led to the Braak hypothesis of misfolded α-syn commencement in the ENS and propagation to brainstem nuclei including the SNpc via the vagus nerve. Altered or stressed gut environment is thought to contribute to the misfolding of α-syn that subsequently initiates or spurs its propagation from the gut myenteric plexus. This review covers clinical and pre-clinical evidence of the involvement of enteric α-syn in PD related to GI dysfunction and brain pathology.","PeriodicalId":92384,"journal":{"name":"International journal of neurodegenerative disorders","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43744263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"The Experience of Parkinson's Disease in Hai District, Tanzania","authors":"Fothergill-Misbah Natasha, Dotchin Catherine, Kisima John, H. Kate, Walker Richard","doi":"10.36959/459/606","DOIUrl":"https://doi.org/10.36959/459/606","url":null,"abstract":"Background: Parkinson’s disease (PD) is a debilitating neurological disease that can result in a reduced quality of life for people with Parkinson’s disease (PwP) and their families. The incidence of PD continues to increase as the global population ages, as is being experienced in Tanzania and much of sub-Saharan Africa, yet healthcare systems are under-developed and not prepared to manage the burden posed by chronic conditions. Little is known about people’s experiences of long-term drug treatment for PD and the impact disease progression has on PwP and their families’ lives. This paper outlines findings from a small-scale qualitative research study on the experiences of PwP in later stages of illness and their families in the Hai district of Tanzania. Methods: Semi-structured biographical in-depth interviews were conducted with three PwP and six caregivers in the Hai district of Tanzania. Interviews explored participants’ experiences of living with PD and caring for a family member with PD, their response to biomedical treatment, use of alternative treatment practices and understanding about the disease. Results: PWP and caregivers all expressed the emotional, social, physical and economic strain of PD. PwP felt angry and frustrated with their deteriorating condition and increasing dependence but pleased with the treatment. Caregivers described the full-on nature of their caring role which resulted in increasing social isolation, worry and stress as the PwPs’ condition progressed. Religion, faith and prayers played a significant role in disease management in combination with pharmaceutical treatment. Participants did not report any stigmatisation towards PwP from communities. Conclusion: This study outlines the emotional, financial and physical challenges that PwP at advanced disease stages and their caregivers experienced in the Hai district. It highlights the need for PD management to acknowledge the role of spiritual healing and social support in combination with biomedical treatment to achieve effective care and improve the wellbeing of PwP and their families, and the need for increased awareness and understanding about PD in the region.","PeriodicalId":92384,"journal":{"name":"International journal of neurodegenerative disorders","volume":"43 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88182041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
