Comprehensive Assessment of Microplastic Toxicity in a Diabetic Model with Emphasis on Neurological Consequences
AI summary Read the abstract
Researchers assess microplastic neurotoxicity in a diabetic animal model, finding that even at ambient environmental concentrations, both acute and chronic microplastic exposure impairs neurological functions including memory, behavior, and cognitive processes, with diabetic physiology potentially amplifying these adverse effects on the nervous system.
Nervous system is primarily responsible for an organism’s ability to regulate its memory, behaviour and cognitive processes. The neurotoxic consequences of microplastics are a developing concern nowadays. Even at ambient concentrations, both acute and long-term...

Invisible threats of microplastics induced toxicity: Oxidative and inflammatory pathways in the CNS and retina
AI summary Read the abstract
Tiny plastic particles that we ingest and breathe in every day may be able to sneak past the brain's and eye's natural protective barriers, where they can trigger inflammation and stress cells out, potentially playing a role in conditions like Alzheimer's, Parkinson's, and macular degeneration. This review pulls together existing animal and lab research on the topic, but it's important to note that solid proof in humans is still lacking, partly because these particles are so hard to detect and study. Still, given how common microplastic exposure has become, the findings are a strong signal that we need more research to understand what this means for long-term brain and eye health.
Micro and Nanoplastics: Impact on Cellular Health and Neuro-Function
AI summary Read the abstract
Researchers reviewed how micro- and nanoplastics ubiquitous in air, water, and soil can enter cells and disrupt neurological function, with evidence linking MNP exposure to oxidative stress, cellular damage, and impairment of neural signaling pathways.
The toxicity of polyethylene microplastics on molecular and biochemical parameters in albino mice
AI summary Read the abstract
Researchers assessed the molecular and biochemical effects of polyethylene microplastic exposure in albino mice, finding dose-dependent toxicity across multiple organ systems, with measurable alterations in liver enzymes, oxidative stress markers, and blood cell parameters consistent with systemic health impacts.
Biochemical Effects of Microplastics on Human Health: A Comprehensive Review
AI summary Read the abstract
A comprehensive review documents how microplastics enter the human body through ingestion, inhalation, and skin contact, then reach the lungs, liver, kidneys, brain, and reproductive organs, triggering oxidative stress, inflammation, endocrine disruption, and genotoxicity. These biochemical pathways link microplastic exposure to serious chronic conditions including metabolic syndrome, neurodegenerative disease, reproductive dysfunction, and cancer.
