Stem cell study paves the way for patient therapies

Stem cell study paves the way for patient therapies

Stem cells that have been specifically developed for use as clinical therapies are fit for use in patients, an independent study of their genetic make-up suggests. The research – which focused on human embryonic stem cells – paves the way for clinical trials of cell therapies to treat conditions such as Parkinson’s disease, age-related degeneration of the eyes and spinal cord injury.

Immune gene prevents Parkinson’s disease and dementia

Immune gene prevents Parkinson's disease and dementia

An estimated seven to ten million people worldwide are living with Parkinson’s disease (PD), which is an incurable and progressive disease of the nervous system affecting movement and cognitive function. More than half of PD patients develop progressive disease showing signs of dementia similar to Alzheimer’s disease.

Smart cells teach neurons damaged by Parkinson’s to heal themselves

UNC smart cells teach neurons damaged by Parkinson's to heal themselves

These are white blood cells reengineered by scientists at UNC-Chapel Hill deliver exosomes (red) loaded proteins that stimulate the growth of damaged nerve fibers (green and yellow). Researchers at the UNC Eshelman School of Pharmacy this technique can be developing into a potential treatment for Parkinson’s disease.

As a potential treatment for Parkinson’s disease, scientists at the University of North Carolina at Chapel Hill have created smarter immune cells that produce and deliver a healing protein to the brain while also teaching neurons to begin making the protein for themselves.

Neuronal disorders and energy metabolism

Neuron energy metabolism
Mitochondria are responsible for creating more than 90 percent of the energy needed by the body to sustain life and support growth. ATP energy is produced when the mitochondria transfers glucose and oxygen into water and carbon dioxide. How ATP is produced and delivered to intricate neuronal dendrites has been a mystery.

Scientists in Japan have have discovered how nerve cells adjust to low energy environments during the brain’s growth process. Their study may one day help find treatments for nerve cell damage and neurodegenerative disorders such as Alzheimer’s and Parkinson’s diseases.
