Opioid-induced microbial dysbiosis
Popjak, Šimon ; Drastichová, Zdeňka (advisor) ; Stehlíková, Zuzana (referee)
The aim of this bachelor thesis is to describe the consequences of opioids in relation to the gut microbiome. Chronic opioid use induces microbial dysbiosis in the gut, where both functional and structural changes in the composition of the microbiome occur. This disrupts gut homeostasis and leads to diseases. The diversity of microbial organisms decreases and the expression of neurotransmitters changes. Opioids interfere with the microbiomeň-gut-brain axis, which normally functions in symbiosis. They alter the composition of the gut microbiota, affect the function and structure of the gut epithelium and the expression of neurotransmitters in the nervous system. This thesis focuses primarily on the action of morphine, the action of which has been desribed the most. Keywords: opioids, microbiome, dysbiosis, microbiome-gut-brain axis, gut homeostasis
