Whats is Optogenetics

From Wikipedia, the free encyclopedia
Optogenetics (from Greek optikós], meaning “seen, visible”) is a biological technique which involves the use of light to control cells in living tissue, typically neurons, that have been genetically modified to express light-sensitive ion channels. It is a neuromodulation method employed in neuroscience that uses a combination of techniques from optics and genetics to control and monitor the activities of individual neurons in living tissue—even within freely-moving animals—and to precisely measure the effects of those manipulations in real-time.[1] The key reagents used in optogenetics … Read more

Gene therapy for osteoarthritis ?

GeneQuine develops drugs that are based on gene therapy. The concept of gene therapy is to introduce genetic material into the patient’s own cells in the body. The cells produce then a therapeutic protein according to the template that the introduced genetic material (DNA) provides

GeneQuine is focused on the development of gene therapy agents for the treatment of osteoarthritis. Osteoarthritis is a degenerative joint disorder characterized by cartilage loss and inflammation. Patients affected by osteoarthritis experience joint pain as well as swelling and stiffness of the joints leading to … Read more

Gene therapy for spinal muscular atrophy (SMA) Type 1


Gene therapy is a well-suited approach for the treatment of SMA due to the monogenic nature of the disease—meaning it’s caused by the deletion of or mutations in a single gene. AVXS-101 is our clinical-stage, proprietary gene therapy candidate of a one-time, intravenous treatment for SMA Type 1—designed to prevent further muscle degeneration caused by SMA through:

Delivery of a fully functional human SMN gene into target motor neuron cells
Production of sufficient levels of SMN protein required to improve motor neuron function
Rapid onset of effect in addition to … Read more
