Glial cell line-derived neurotrophic factor. Potential for otoprotection.

Abstract:

:Sensorineural hearing loss results from the degeneration of hair cells and/or auditory neurons in the cochlea of the inner ear. BDNF and NT-3 were shown to support survival of auditory neurons both in vitro and in vivo. Cochlea from P3-P4 rats were cultured as floating explants and hair cells in the organ of Corti were identified by phalloidin-FITC immunostaining. Treatment with cisplatin (35 micrograms/mL) or neomycin (0.6 mM) resulted in 21.2 +/- 6.0% and 7.4 +/- 4.7% surviving hair cells, respectively, after 3 days in culture. GDNF, added together with the ototoxins, increased their number to 46.7% and 37.4%, respectively. In cultures of dissociated cochlea from 4-week-old rat, cisplatin (5 mg/mL) added 24 h after seeding resulted in only 6.1 +/- 1.2% surviving neurons. However, when cisplatin was added together with GDNF (10 ng/mL), 32.8 +/- 1.0% of the neurons survived. The efficacy of GDNF in animal models of ototoxicity was tested next. Guinea pigs were pretreated with GDNF in one ear, delivered either by infusion into the inner ear (scala tympani) with Alzet minipumps (50 ng/mL at a 0.5 microL/h), or injected into the middle ear (120 microL at 1 mg/mL) through the tympanic membrane. The ear that did not receive GDNF always served as control. Ototoxicity was induced systemically either by intraperitoneal cisplatin injections (1 mg/kg/day for 15 days or two injections of 7.5 mg/kg at a 5-day interval or by a combination of kanamycin (200-300 mg/kg, administered subcutaneously) and ethacrinic acid (40 mg/kg, intravenous). It was found that the number of surviving hair cells in GDNF-treated ears was about twice that of control ears in animals exposed to the ototoxins. The transducing GDNF receptor (ret) is expressed in the inner ear.
