Retinal photograph taken more than two years after subretinal injection of AAV2-hRPE65v2 in the second eye of a dog model of Leber's congenital amaurosis due to RPE65 mutations. The AAV-exposed portion of the retina, with the overlying inner retinal blood vessels, appears yellow due to reflective changes in the underlying tapetum.

Second Dose Of Gene Therapy For Inherited Blindness Proves Safe In Animal Studies

Rapamycin Rescues Learning And Memory In An Alzheimer’s Disease Mouse Model

Rapamycin, a drug that keeps the immune system from attacking transplanted organs, may have another exciting use: fighting Alzheimer’s disease. Rapamycin rescued learning and memory deficits in a mouse model of Alzheimer’s, a team from The University of Texas Health Science Center at San Antonio reported Tuesday (Feb. 23). The study, in the Journal of […]
