REMEDY FOR DISEASE ASSOCIATED WITH APOPTOTIC DEGENERATION IN OCULAR CELL TISSUE WITH THE USE OF SIV-PEDF VECTOR

摘要

It is intended to provide a novel method of treating a diseases associated with apoptotic degeneration in an ocular cell tissue by effectively administering pigment epithelium-derived factor (PEDF). Attentions are focused on PEDF as a novel means of preventing neural ganglion death which is the final pathological stage in glaucoma. Further, attentions are paid to an SIV vector as an effective method of delivering PEDF and an SIV-PEDF vector is constructed. When the SIV-PEDF vector is subretinally administered to an ischemic reperfusion model and an NMDA-induced model, it is observed that neural ganglion death is remarkably inhibited. Thus, it is found out that the SIV-PEDF vector is efficacious as a drug for treating a diseases associated with apoptotic degeneration in an ocular cell tissue such as glaucoma.
