Did you know that around 70% of the body’s immune cells are concentrated in the gut? In this video, we explore how micro- and nanoplastics affect the body’s biological barriers and the human microbiota.
The intestinal barrier functions as a complex filter, allowing nutrients to pass through while blocking foreign particles. However, recent studies suggest that electrostatically charged plastic nanoparticles may alter the permeability of this barrier. The walls of the intestine contain approximately 500 million neurons directly connected to the brain via the vagus nerve — a system known as the “gut–brain axis.”
We analyze data on how the presence of nanoparticles may disrupt the balance of the 100 trillion bacteria that make up our microbiota. The video also examines the phenomenon of the “biocorona,” in which plastic particles become covered with plasma proteins, making them less detectable by the body’s defense systems. Understanding these processes is critically important for protecting human health in the modern world and for advancing preventive medicine.
