ClearThe microplastic-crisis: Role of bacteria in fighting microplastic-effects in the digestive system
This review examines how microplastics affect the human digestive system and explores whether certain bacteria could help counteract the damage. Microplastics disrupt the gut by altering microbial communities, interfering with digestive enzymes, and damaging the protective mucus lining. The authors highlight the potential for probiotic bacteria to bind to microplastics, reduce inflammation, and help repair the gut environment, offering a possible protective strategy against microplastic-related digestive harm.
The ant that may well destroy a whole dam: a systematic review of the health implication of nanoplastics/microplastics through gut microbiota
This systematic review summarizes existing research on how nanoplastics and microplastics disrupt gut bacteria in various organisms.

Polystyrene microplastics induce an immunometabolic active state in macrophages
Researchers found that polystyrene microplastics taken up by macrophages — immune cells lining the gut and lungs — triggered a metabolic shift toward an inflammatory state. This finding suggests microplastics reaching human tissues may alter immune function in ways that could contribute to inflammation-related diseases.
Micro(nano)plastics and Their Potential Impact on Human Gut Health: A Narrative Review
This review summarizes research on how micro- and nanoplastics affect the gut, finding that they can damage the intestinal lining, trigger immune responses, and disrupt the balance of beneficial gut bacteria in both cell studies and animal models. Since humans are primarily exposed to microplastics through food and food packaging, understanding these gut effects is essential for assessing the true health risks of plastic pollution.

Microplastic-mediated new mechanism of liver damage: From the perspective of the gut-liver axis
This review describes how microplastics can damage the liver through the gut-liver axis: they first disrupt the gut's protective barrier and beneficial bacteria, allowing harmful substances to leak through the weakened intestinal wall into the bloodstream and travel to the liver. Once there, these substances cause inflammation, metabolic problems, and oxidative stress, offering a new explanation for how microplastic exposure could lead to liver disease.
The whole life journey and destination of microplastics: A review
This review traces the full journey of microplastics from their environmental sources through their various pathways into the human body, and what happens once they get inside.
