Chemical-induced inflammation and inflammatory diseases
1School of Biological Sciences, University of Surrey Guildford, United Kingdom.
Summary
Chemicals can trigger hidden inflammatory diseases by producing reactive oxygen species (ROS). Antioxidants protect against this toxicity, while fasting and alcohol worsen it, potentially leading to chronic conditions like cancer.
Area of Science:
- Toxicology
- Immunology
- Environmental Health
Background:
- Chemical exposure can lead to adverse health effects not immediately recognized as toxicity.
- These effects include inflammatory conditions such as hepatitis, nephritis, scleroderma, and lupus.
Purpose of the Study:
- To elucidate the mechanisms by which chemical exposure induces inflammatory and immunotoxic effects.
- To identify protective factors and exacerbating factors in chemical-induced toxicity.
Main Methods:
- The study discusses the role of reactive oxygen species (ROS) production via cytochrome P4502E1 activation.
- It highlights the metabolism of chemicals into reactive intermediates and neoantigens.
- It reviews the protective roles of intracellular glutathione (GSH) and vitamins C, E, and A.
Main Results:
- Chemicals can induce inflammation and immunotoxicity through ROS production or reactive metabolites.
- Fasting and alcohol consumption were identified as factors that exacerbate chemical toxicity.
- Chronic inflammatory conditions, including rheumatoid disease, atherosclerosis, diabetes, Alzheimer's disease, and cancer, may develop.
Conclusions:
- Chemicals pose a significant risk for inducing a range of inflammatory and immunotoxic effects.
- Understanding these mechanisms is crucial for preventing chronic diseases linked to chemical exposure.
- Antioxidants play a vital role in mitigating ROS-induced damage, while lifestyle factors like diet and alcohol intake can influence susceptibility.
