Lycium barbarum Glycopeptide Alleviates Neomycin-Induced Ototoxicity by Inhibiting Tryptophan Hydroxylase-Mediated Serotonin Biosynthesis.

ABSTRACT: Aminoglycoside antibiotic-induced sensorineural hearing loss (SNHL) is a common sensory disorder that requires the development of prophylactic and therapeutic interventions. Lycium barbarum glycopeptide (LBGP) is a peptidoglycan isolated and purified from Lycium barbarum polysaccharides that exhibit significant anti-inflammatory, antioxidant, and neuroprotective effects, but the role of LBGP in aminoglycoside-induced SNHL has not been well investigated. Here it is shown that LBGP can protect against neomycin-induced hearing impairment and alleviate oxidative stress in a neomycin-induced SNHL mouse model. Moreover, it is further found that inhibition of tryptophan hydroxylase (Tph)-mediated serotonin (5-HT) biosynthesis plays a key role in the mechanism of action of LBGP in treating neomyci
