Counting (on) Sheep: Gene therapy research on visually impaired sheep now safe for human trials

In 2009, a group of the Hebrew University of Jerusalem researchers led by Ron Ofri, a Professor of Veterinary Ophthalmology, along with teams from Hadassah Medical Center (led by Professor Eyal Banin) and the Volcani Agricultural Research Organization (led by Professor Elisha Gootwine), identified a herd of sheep suffering from day blindness.

As the name implies, affected lambs are blind at day, and visual at night. The researchers characterized the disease and were able to demonstrate that it is caused by a mutation identical to one causing achromatopsia in humans. Achromatopsia is a similar disease, in which the absence of retinal cone function causes loss of color vision, severely reduced visual resolution, and legal blindness in human patients. More interestingly, the specific form of the disease discovered in sheep is the one that is most common in Israeli patients, and in the Jerusalem-area alone, the prevalence of achromatopsia is as high as 1:5,000 people.

Because of the similarity between the ovine(sheep) and human diseases, Professor Ron Ofri and his colleagues began gene therapy trials in the affected animals. A virus carrying a copy of the mutated gene was injected beneath the retina and began producing the missing protein.  The treatment resulted in restored vision in treated eyes, while untreated eyes remain blind. Even more remarkable is that the oldest surviving experimental animals are still visual more than six years after a single injection, a significant scientific and medical achievement that did not escape the attention of the prestigious journal Human Gene Therapy which featured Professor Ofri’s accomplishment.

Based on these results, showing both long-term effectiveness and safety of treatment in the sheep models, the United States FDA last year granted permission to begin clinical trials in human patients (NCT02935517), and several medical centers in the U.S. have already begun treating achromatopsia patients. The Israeli Ministry of Health has just granted similar approval, and clinical trials will begin shortly in Israel. These approvals, coming less than 10 years since the discovery of the original sheep herd, represent a remarkable example of a translational, bench to patient bedside study, where successful scientific results are applied to restore vision in blind human patients.

Koalas, horses and pygmy goats (oh my!) in Israeli-UC Davis vet team-up

A list of the collaborative work between the UC Davis School of Veterinary Medicine and the Koret School of Veterinary Medicine — the only veterinary school in Israel — reads something like a “who’s who” of the animal kingdom.

Nearly 65,000 cats, dogs, horses, cows and goats (including pygmy and Nubian varieties) are cared for annually at the Davis and Rehovot facilities, along with the occasional gorilla, koala and wallaby.

Though 7,300 miles apart, the universities have been collaborating on research, grants, academic papers and faculty exchanges for more than three decades, thanks to support from an endowment at the S.F.-based Koret Foundation.

Not Just a One Trick Pony

This is a story about an amazing horse that demonstrates the expertise and dedication of the doctors and staff at the Hebrew University of Jerusalem’s Veterinary Hospital.

At the beginning of the year,  Keshet, then a three-week-old foal, was brought into the horse department at the Veterinary Hospital because of a sudden paralysis she experienced in all four of her legs. After a comprehensive diagnosis, which included blood tests, spinal cord sampling (CSF), X-rays, and a CT scan, doctors found an infection that pressed her spinal cord. This type of infection is very rare in horses and veterinary literature reports only one case.

Despite the critical condition of young Keshet, her owner decided to treat her in the hopes the horse could live a happy and healthy life. Keshet had two emergency surgeries and was treated with high doses of medicine and liquids.

After five days, when Keshet was stronger but could still not stand, she was scheduled for another emergency operation, to clean the infection again. But a few hours before the surgery, she showed repeated attempts to stand up and on the morning of the scheduled operation, she managed to stand on her own and was able to nurse on her own.

Since then, Keshet continues to show incredible improvement every day. She can get up and lie down on her own, walk, nurse, eat hay and drink water. A later CT scan showed the infection was immensely diminished but still present. Luckily, the infection was not straining her spinal cord, so the doctors decided not to operate but to switch antibiotics. While expensive, the new medicine is essential because it penetrates the bones effectively.


Keshet was also fitted with a brace to help stabilize her right front leg. After a short amount of time, the brace was removed and Keshet is able to move slowly and carefully.

This spirited and persistent little horse is an inspiration to her main caregiver, Dr, Anat Schneiderman and to many who hear her story. While she still has a long way to go in her recovery,  Keshet continues to fight and get better day by day.
