Intracerebroventricular (i.c.v.) infusion of norepinephrine (NE) decreases neuroprogenitor cell (NPC) proliferation (arrows) within the subventricular zone (SVZ) of the lateral ventricles (LV) and neurogenesis in the SVZ ‐olfactory bulb system without changing cells type composition of the SVZ. In contrast, pharmacological NE inhibition increases the proliferation of various NPC types and early neurogenesis events in the caudal periventricular niche (PGN) of the third ventricle (3 V). Neurotoxic ablation of nore pinephrine neurons within theLocus coeruleus (LC) using Dsp4 confirms the inhibitory effects of NE on N...

AbstractThere is escalating interest in cell-based therapies to restore lost dopamine inputs in Parkinson ’s disease. This is based upon the rationale that implanting dopamine progenitors into the striatum can potentially improve dopamine-responsive motor symptoms. A rich body of data describing clinical trials of previous cell transplantation exists. These have included multiple cell sources for tran splantation including allogeneic (human embryonic mesencephalic tissue, retinal pigment epithelial cells) and autologous (carotid body, adrenal medullary tissue) cells, as well as xenotransplantation. However, there are...

(University of Copenhagen The Faculty of Health and Medical Sciences) Stem cell researchers from the University of Copenhagen have designed a model of an early embryonic brain. The model will increase our understanding of how the human brain develops and can thereby help to accelerate the development of stem cell treatments for brain disorders such as Parkinson's disease, epilepsy and dementia.

This study provides direct evidence for the contribution of gut microbiota to the cognitive decline during normal aging and suggests that restoring microbiota homeostasis in the elderly may improve cognitive function. On Nutraceutical Senolytics https://www.fightaging.org/archives/2020/05/on-nutraceutical-senolytics/ Nutraceuticals are compounds derived from foods, usually plants. In principle one can find useful therapies in the natural world, taking the approach of identifying interesting molecules and refining them to a greater potency than naturally occurs in order to produce a usefully large therape...

CONCLUSION: Research has shown that insulin insensitivity in T2DM leads to neurodegeneration through mechanisms involving a variety of extracellular, membrane receptor, and intracellular signaling pathway disruptions. Some therapeutics, such as intranasal administration of insulin and neuroactive substances have shown promise but face problems related to genetic background, accessibility to the brain, and invasiveness of the procedures.

n;a V Abstract We have recently demonstrated that extracellular vesicles (EVs) derived from the human teeth stem cells improve motor symptoms and normalize tyrosine hydroxylase (TH) expression in the nigrostriatal structures of Parkinson's disease (PD) model rats obtained by 6-hydroxydopamine (6-OHDA) unilateral injection into the medial forebrain bundle (MFB). The aim of this study was to clarify: (1) how long therapeutic effects persist after discontinuation of 17-day intranasal administration of EVs in 6-OHDA rats; (2) may EVs reverse cognitive (learning/memory) dysfunction in these PD model rats; (3) whether a...

WEDNESDAY, May 13, 2020 -- In a first, scientists have treated a Parkinson's disease patient with his own skin cells -- repurposing them to become key brain cells that the disease kills off. Two years after receiving the experimental treatment, the...

In 2017, Harvard stem cell biologist Dr Kwang-Soo Kim took skin cells from George Lopez, reverted them to stem cells, then made those into dopamine neurons, which were injected into Lopez's brain.
