Fumonisin B2 is primarily studied in the context of its toxicological effects, particularly in agriculture and food safety. It is a mycotoxin produced by Fusarium species, often found in contaminated corn and other cereals. Research focuses on its impact on livestock and human health, as ingestion can lead to diseases such as equine leukoencephalomalacia in horses and potentially carcinogenic effects in humans. Efforts are made to develop detection methods and mitigation strategies to reduce its presence in food and feed. Additionally, studies explore its role in disrupting sphingolipid metabolism, which is crucial for understanding its toxic mechanisms and developing potential therapeutic interventions.
