Insights

Adult stem cells (ASC) show promise for treating Parkinson's disease (PD) by potentially rescuing neurons and improving motor function. Clinical trials suggest neurorescue effects, particularly in early PD stages.

Area of Science:

  • Neuroscience
  • Regenerative Medicine
  • Stem Cell Biology

Background:

  • Parkinson's disease (PD) is a progressive neurodegenerative disorder affecting millions globally.
  • Current PD therapies are symptomatic, highlighting the need for neuroprotective strategies.
  • Adult stem cells (ASC) possess properties like transdifferentiation and immunomodulation, suggesting therapeutic potential.

Purpose of the Study:

  • To evaluate the efficacy of adult stem cells (ASC) as a neuroprotective strategy for Parkinson's disease (PD).
  • To investigate the potential of ASCs to promote neurorescue and improve motor function in PD models and patients.

Main Methods:

  • Preclinical studies utilized 6-hydroxydopamine (6-OHDA) and MPTP-lesioned animal models.
  • Histological and histochemical analyses assessed changes in Tyrosine Hydroxylase-positive (TH+) cells and dopamine levels.
  • Limited clinical investigations involved subventricular or intravasal ASC applications in PD, MSA, and PSP patients.

Main Results:

  • ASC treatment in animal models led to persistent motor behavior improvements.
  • Intracerebral ASC application increased TH+ cells and striatal dopamine levels, indicating cell rescue.
  • Early-phase PD patients showed encouraging neurorescue with subventricular ASCs, while MSA/PSP patients had marginal benefits.

Conclusions:

  • ASCs demonstrate potential for neuroprotection and motor function improvement in Parkinson's disease.
  • Evidence suggests ASCs can promote neurorescue, particularly in the early stages of PD.
  • Further research is needed to optimize ASC therapy for various neurodegenerative conditions like MSA and PSP.

Parkinson's Disease: Treatment

Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of its...
Parkinson's Disease: Overview01:15

Parkinson's Disease: Overview

Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is to...

Parkinson Disease ll: Pathophysiology

Parkinson disease (PD) is a progressive neurodegenerative disorder primarily affecting movement, with additional non-motor features. Its pathophysiology involves complex interactions among genetic susceptibility, environmental exposures, and cellular dysfunction, including dopaminergic neuron loss, protein aggregation, and mitochondrial impairment.Selective NeurodegenerationA key feature is the degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to reduced...
Parkinson Disease l: Introduction01:24

Parkinson Disease l: Introduction

Parkinson’s disease is a chronic, progressive neurodegenerative disorder that primarily affects movement. It is characterized by motor symptoms such as resting tremors, muscle rigidity, bradykinesia (slowness of movement), and postural instability. Patients may notice hand tremors at rest, stiffness during movement, or a shuffling gait. In addition to motor features, non-motor symptoms include sleep disturbances, mood and behavioral changes, constipation, and cognitive impairment, all of which...

EPS and iPS Cells in Disease Research

Embryonic and induced pluripotent stem cells are excellent models for disease research because of their ability to self-renew and differentiate into most cell types. Somatic cells from a patient are isolated and reprogrammed into induced pluripotent stem cells or iPSCs. These iPSCs are later differentiated into the desired cell type, which mirrors the diseased cell of the patient. In this way, disease models have been created for investigating diseases such as Down syndrome, type I diabetes,...

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.
