Gene therapy delivery of nerve growth factors reverses erectile dysfunction in animal model

ith rats treated with the control virus or untreated mice with ED. Rats treated with HSV-neurturin also exhibited significant recovery of ICP and AP compared with the control or untreated mice at four weeks after treatment. Fluorescent protein studies also showed that the delivered genes had been effectively incorporated into the target nerve cells.

According to Dr. Glorioso, HSV delivery of GDNF or neurturin presents a potentially important new approach for the treatment of ED. "Because the herpes virus persists in the nerve cell for as long as it is alive and nerve cells typically do not reproduce, this represents the first-ever demonstration of a long-term treatment for ED that does not rely on the chronic administration of drugs that can have potentially harmful side effects," he explained.
