Glial-cell-line-derived neurotrophic factor (GDNF) acts as a potent survival factor for many neuronal populations, including retinal ganglion cells (RGC), indicating a potential therapeutic role of GDNF for neurological disorders. To enhance the tissue distribution and applicability of the neurotrophin, we linked it to a protein transduction domain derived from the HIV TAT protein and tested it in a well-established model for traumatic injury in the CNS: After optic nerve axotomy, the number of surviving RGCs was significantly increased in mice injected with TAT-GDNF on days 0, 3, 7, and 10 after surgery compared with GDNF- or PBS-injected animals. Moreover, TAT-GDNF reduced the number of activated caspase-3-positive cells. These results show that the neuroprotective effect of substances like neurotrophins may be enhanced by linking them to a domain that has been shown to mediate efficient transduction across biological membranes.
