Abstract

Mycotoxins, such as Ochratoxins, are widely distributed in nature and are common contaminants of human foodstuffs. Ochratoxins are a group of mycotoxins produced by a wide range of molds. Ochratoxin A (OTA), the most prominent member of this toxin family, is produced by various Aspergillus and Penicillium species. OTA is frequently found in foods such as cereals, oleaginous seeds, coffee, and meat products. This mycotoxin has been described as teratogenic, genotoxic, carcinogenic, and immunotoxic, and has been proven to be a potent neurotoxin. In the present study, the neurotoxicological perspective of OTA was reviewed and discussed. The main possible mechanisms of neurotoxicity are oxidative DNA, protein and lipid damage, and apoptosis. However, further studies are needed to conclude the exact neurotoxicity mechanism of OTA and find the approaches that reduce the neurotoxicity induced by OTA.
