Pulmonary metabolism of foreign compounds: its role in metabolic activation.
نویسنده
چکیده
The lung has the potential of metabolizing many foreign chemicals to a vast array of metabolites with different pharmacological and toxicological properties. Because many chemicals require metabolic activation in order to exert their toxicity, the cellular distribution of the drug-metabolizing enzymes in a heterogeneous tissue, such as the lung, and the balance of metabolic activation and deactivation pathways in any particular cell are key factors in determining the cellular specificity of many pulmonary toxins. Environmental factors such as air pollution, cigarette smoking, and diet markedly affect the pulmonary metabolism of some chemicals and, thereby, possibly affect their toxicity.

Gut microbiota regulates the production of signaling molecules, such as serotonin or 5-Hydroxytryptamine: 5-HT in the host. Serotonin is a biogenic amine that acts as a neurotransmitter in the gut and brain. There is a perfect interaction between human gastrointestinal microbiota and the serotonin system. The gut microbiota plays an important role in the serotonin signaling pathways through the...
