Arizona State to grow human neurons, test treatments for neurodegenerative diseases

(Arizona State University) Lab-grown human neurons will be used to develop and test treatments for devastating neurodegenerative diseases, particularly Alzheimer's disease, Parkinson's disease and Amyotrophic lateral sclerosis.

Chivero, Shilpa BuchAbstractPlatelet-derived growth factors (PDGFs) and their receptors (PDGFRs) are expressed in several cell types including the brain cells such as neuronal progenitors, neurons, astrocytes, and oligodendrocytes. Emerging evidence shows that PDGF-mediated signaling regulates diverse functions in the central nervous system (CNS) such as neurogenesis, cell survival, synaptogenesis, modulation of ligand-gated ion channels, and development of specific types o...

Thus, having great potential for investigating neurodegeneration in Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and mild cognitive impairment, speciation is increasingly considered in epidemiological or clinical neurological studies. This review analyses recent speciation findings in neurodegeneration r...

Multiple factors are involved. Elevated serum levels of cytokines, catecholamine, granulocyte colony stimulating factor, peripheral blood hematopoietic progenitor cells (HPCs) and decreased expression of erythropoietin receptor are associated with HF among T/HS. HF leads to anaemia, susceptibility to infection, sepsis and multi-organ failure. There is a lack of molecular underst...

Abstract Neurodegenerative proteinopathies are a group of pathologically similar, progressive disorders of the nervous system, characterised by structural alterations within and toxic misfolding of susceptible proteins. Oligomerisation of Aβ, tau, α-synuclein and TDP-43 leads to a toxin gain- or loss-of-function contributing to the phenotype observed in Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis and frontotemporal dementia. Misfolded proteins can adversely affect mitochondria, and post-mitotic neurones are especially sensitive to metabolic dysfunction. Misfolded proteins imp...

The reasons why restoration of cerebrospinal fluid drainage is a very promising strategy for the treatment of Alzheimer's disease go beyond the compelling direct evidence, into matters of research and development strategy. Numerous proteins that become misfolded or altered in ways that cause them to form solid deposits in the aging brain, surrounded by a halo of harmful secondary biochemistry. To date, serious development efforts that have advanced to clinical trials have focused on clearing only one of these aggregates. That may well never be enough: neurodegeneration appears to be a combination of the effects of many mec...
