Microplastics on the brain?

According to a recent study, microplastics affect all of the body’s systems and alter behavior.
Microplastic contamination of mammals is much more pervasive than previously believed, according to a recent study by University of Rhode Island Professor Jaime Ross. In fact, it was discovered that the plastic particles bioaccumulated in every organ, shockingly even the brain.

One of the most pervasive contaminants on the globe is microplastics. All around the world, they have been found in food chains, water systems, and the atmosphere. Few research have looked at the potential health effects on mammals, despite the fact that their detrimental effects on marine organisms have been documented.

Ross, an assistant professor of biomedical and pharmaceutical sciences at the Ryan Institute for Neuroscience and the College of Pharmacy, stated that there is still a dearth of information regarding the effects of microplastics on human health, particularly in mammals.

Humans are exposed to microplastics through ingestion of “water, seafood, consumer products (clothes, toothpaste, salt, sugar, honey, beer, anything stored in plastic bottles, plastic wrap, or cans/cartons lined with plastic),” as well as through inhalation of “textiles, synthetic rubber tires, and plastic covers,” according to the study. They have been found in blood and even breast milk, among other places, which calls for further research into the effects on mammal health of such exposure.

Ross and her team chose to concentrate on neurobehavioral effects and inflammatory response to exposure to microplastics, as well as the accumulation of microplastics in tissues because there are currently few studies that address the potential adverse effects of exposure to MPs on the health of the mammalian brain and even fewer studies that take age into account as an extra element that might affect how exposure to microplastics plays out. She studied the effects of mice’s exposure to microplastics on their biology and cognition along with graduate students Sydney Bartman and Lauren Gaspar.

Over the course of three weeks, microplastics were added to the water of a diverse collection of older and younger mice, with “striking” outcomes, according to Ross. The researchers discovered that exposure to microplastics—in this case, fluorescent polystyrene particles—caused changes in immunological markers in the liver and brain tissues as well as behavioral changes. The study’s mice started to move strangely and display behaviors resembling dementia in people. Older animals showed much more dramatic results.

These changes were noticeable quickly, according to Ross. These microplastic levels weren’t particularly high. “How long is one of the issues we wish to consider these microplastics survive in the body because nobody really understands how long they do is what happens as you age. Do these microplastics make you more prone to systemic inflammation as you get older? Can they be eliminated by your body as quickly? Do your cells react to these toxins differently?

When the mice were dissected after three weeks, it became clear that every tissue sample tested, including those from the liver, kidney, gastrointestinal tract, lung, heart, and brain tissues of both young and old exposed mice, had been contaminated by the ingested PS micro-particles. Additionally, the particles were found in the mice’s waste products.

The discovery of MPs in organs including the heart and lungs… indicates that PS-MPs (polystyrene microplastics) are traveling outside of the digestive system and probably circulating throughout the body, the authors write. They observe that this is corroborated by the finding of microplastics in the brain and urine, which shows they can cross the blood-brain barrier.

According to research, that brain infiltration may also result in a decline in the protein glial fibrillary acidic protein, or “GFAP,” which supports numerous cell activities in the brain. In earlier stages of various neurodegenerative diseases, such as Alzheimer’s disease, or in younger people with depressive problems, GFAP expression may decline, according to previous studies.

The fact that these modifications were noticed after just three weeks of exposure to microplastics is particularly alarming. Since today’s human exposure is unavoidable, it is crucial to better understand their toxicity in order to reduce their negative effects on human health. The current study demonstrated that in just three weeks, polystyrene particles measuring 0.1 and 2 m can significantly alter immune markers in the liver and the brain, translocate throughout the body, accumulate in tissues like brain tissue, and significantly alter behavior in mice. The results of exposure also appear to vary with age.

In order to comprehend the mechanisms underlying these impacts and the changes brought on by aging, future research is required to look into these variables, according to Ross.

We want to know whether exposure to plastics might cause neurological problems and diseases like Alzheimer’s disease or whether it can alter the brain’s capacity to maintain homeostasis.

In the International Journal of Molecular Science, the work was published.
