- 突出AFB1对家禽健康和公共健康的影响.
主要方法:
- 对现有关于家禽AFB1毒性的研究进行文献综述.
- 对参与AFB1诱导的肝毒性分子通路的分析.
- 综合有关氧化损伤,亡,基因表达,自,热和亡的信息.
主要成果:
- AFB1通过多种分子机制诱导家禽的肝损伤.
- 关键机制包括氧化应激,亡诱导,肝细胞基因表达的改变,以及干扰细胞过程,如自,热和亡.
- 通过CYP450介导的生物转化是AFB1对肝细胞有毒作用的核心.
结论:
- 在家禽中,AFB1通过不同的分子途径对肝脏造成重大损伤.
- 对这些机制的全面理解对于开发有效的AFB1缓解策略至关重要.
- 这一审查为未来研究家禽生产中AFB1排毒的研究提供了基础.

When toxic substances penetrate the human body, they disseminate to various tissues, undergoing metabolic changes. This process yields reactive metabolites that may covalently bind with specific target molecules, resulting in toxicity.
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...

Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.
