by University of Rochester Medical Center Credit: Pixabay/CC0 Public Domain Gene therapy can effectively treat various diseases, but for some debilitating conditions like muscular dystrophies there is a big problem: size. The genes that are dysfunctional in muscular dystrophies are often extremely large, and current delivery methods can’t courier such substantial genetic loads into the body....

Gene therapy protects against motor neuron disease in rats
by Will Cushman, University of Wisconsin-Madison A section of brain tissue from a rat that received a gene therapy targeting the Trk-fused gene. A mutation in that gene is implicated in the development of certain motor neuron diseases. Green arrows highlight neurons expressing elevated levels of the gene following the therapy. Red arrows indicate other nerve...

Is gene therapy the next big step in vision loss treatment?
Diseases that affect the retina, the light-sensitive layer at the back of the eye, are a significant cause of visual impairment and blindness. Gene therapy holds promise for treating some of these conditions, and current research advances may soon shift the therapeutic landscape for eye health. However, many obstacles remain in place, as this Special...

Gene therapy that converts omega-6 to omega-3 fatty acids in the body could combat effects of childhood obesity
Credit: Unsplash/CC0 Public Domain According to the Centers for Disease Control, nearly 20% of children and teens are considered obese. Research shows it can have a dramatic impact on a variety of health conditions, including arthritis, heart conditions and other metabolic problems, and the American Academy of Pediatrics now recommends early and intensive treatment to...

Magnetically regulated gene therapy tech offers precise brain-circuit control
A gene therapy allows precise magnetic field control of specific brain circuits without implanted devices. The image shows restricted mRNA expression of the genetically encoded magnetic sensor (red) in dopaminergic neurons type 2 (green) in the mouse striatum that regulate initiation of movement. Dopaminergic neurons type 1 (cyan) and cell nuclei shown with dapi staining...

100x Improvement in Sight Seen After Gene Therapy Trial
SCIENCE & TECHNOLOGY NEWS The vision of people with a rare inherited condition that causes them to lose much of their sight early in childhood was 100 times better after they received gene therapy to address the genetic mutation causing it. Some patients even experienced a 10,000-fold improvement in their vision after receiving the highest...

New way to extend ‘shelf life’ of blood stem cells will improve gene therapy
SCIENCE & TECHNOLOGY NEWS Researchers have discovered a way to extend the shelf life of blood stem cells outside the body for gene therapy, providing patients with better options and improving their outcomes. Researchers have identified a drug already used for cancer patients, that, when applied to current gene therapy protocols can improve blood stem...
