HD News Site. Gene Therapy News. Gene therapy could correct spelling mistakes in our DNA, while stem cells promise transplant operations that don’t need powerful immune suppressing drugs.
Scientists have now combined the two techniques in a genetic liver disease. Several challenges remain before this could work in Huntington’s disease though. Huntington’s disease is one of many conditions caused by a genetic error. A mistake in the genetic recipe for the huntingtin protein causes HD. All cells carry this mistake in their genetic make-up and, as a result, produce the abnormal protein. Common sense suggests the possibility of just going into cells and ‘surgically’ removing the faulty bit. Stem cells can divide into new stem cells, and develop into specialized cells including neurons. Human beings develop from embryonic stem cells within the womb; these stem cells can form any type of tissue. Growing a new brain or using stem cells to repair the brain is currently well beyond our abilities. Stem Cell News. Many people consider gene silencing the best candidate therapy for Huntington’s disease.
A group led by Dr Jan Nolta has described a new method of getting silencing drugs into cells in a dish using modified bone marrow stem cells. Does this new approach offer benefits over existing technologies? Like most HD researchers, we think gene silencing, or shutting off the expression of the HD gene, is the most exciting treatment option on the short term horizon. HD Extra Simplified.

Public release date: 15-Mar-2012 [ Print | E-mail Share ] [ Close Window ] Contact: Su-Chun Zhang zhang@waisman.wisc.edu 608-265-2543University of Wisconsin-Madison MADISON -- Huntington's disease, the debilitating congenital neurological disorder that progressively robs patients of muscle coordination and cognitive ability, is a condition without effective treatment, a slow death sentence.
But if researchers can build on new research reported this week (March 15, 2012) in the journal Cell Stem Cell, a special type of brain cell forged from stem cells could help restore the muscle coordination deficits that cause the uncontrollable spasms characteristic of the disease. "This is really something unexpected," says Su-Chun Zhang, a University of Wisconsin-Madison neuroscientist and the senior author of the new study, which showed that locomotion could be restored in mice with a Huntington's-like condition.

Individuals at risk for Huntington’s disease (HD) have the option of undergoing genetic testing, which detects the presence or absence of the genetic sequence that causes HD. The decision of whether or not to undergo genetic testing is intensely personal, with many factors to consider. This chapter will provide scientific background information regarding genetic testing for Huntington’s disease.
(For more information on how testing for HD may affect relationships, click here ) HD Future. In order to make predictions about the future spread or decline of Huntington’s Disease, we can draw upon scientific tools from the field of population genetics (see Part I for an introduction to this field).
According to population genetics, genes that make it more difficult for an affected individual to survive to reproductive age will tend to decrease in frequency in a population over time. Such a decrease in frequency is an example of the more general process of natural selection—the elimination of variation that results from differential survival and reproduction.
The gene for HD is a special case in that it primarily affects men and women once they have passed their reproductive years. As a result, those affected by HD as adults will already have reproduced and, by the normal laws of probability (as described here), may already have passed on the harmful gene to their children. Stem Cell Treatment News. Washington: A new technique has been developed by researchers which uses stem cells to deliver therapy that specifically targets the genetic abnormality found in Huntington’s disease.
Huntington’s is a hereditary brain disorder that causes progressive uncontrolled movements, dementia and death. This new approach might block Huntington’s from advancing. Researchers think that the best chance to halt the disease’s progression will be to reduce or eliminate the mutant huntingtin (htt) protein found in the neurons of those with the disease. “For the first time, we have been able to successfully deliver inhibitory RNA sequences from stem cells directly into neurons, significantly decreasing the synthesis of the abnormal huntingtin protein,” Jan A Nolta, principal investigator of the study and director of the UC Davis stem cell program and the UC Davis Institute for Regenerative Cures, was quoted as saying.
