The Claim

Both 50 nm and 500 nm polystyrene particles accumulate primarily in lysosomes after cellular internalization, regardless of whether they enter via endocytosis or passive penetration, indicating that lysosomal sequestration is a common fate for internalized micro(nano)plastics in this cell model.

How it works
1 study reviewed
In plain English

When cells take in polystyrene particles of 50 nm or 500 nm in size, the particles end up mostly inside lysosomes, whether they enter through active uptake or passive entry.

See the scientific wording

Both 50 nm and 500 nm polystyrene particles accumulate primarily in lysosomes after cellular internalization, regardless of whether they enter via endocytosis or passive penetration, suggesting lysosomal sequestration is a common fate for internalized micro(nano)plastics in this cell model.

Why this might work

When tiny plastic particles enter a cell, they either slip through the membrane or get swallowed by the cell. Either way, they end up in a special compartment called the lysosome, which acts like a recycling center. The cell uses energy to move the particles there, no matter how they got in. Once inside the lysosome, the particles stay trapped until the cell pushes them back out through another energy-driven process.

  1. Study: Cellular internalization and release of polystyrene microplastics and nanoplastics.

    When tiny plastic particles get inside rat cells, no matter how they sneak in, they eventually end up in the cell’s recycling center called the lysosome. This happens whether they’re small or medium-sized.
