Polystyrene Nanoplastics Induce Pyroptosis in HepG2 Cells via the YAP1-cGAS-STING Signaling Axis.
Summary
Scientists found that tiny plastic particles from polystyrene (commonly used in disposable cups and food containers) can trigger a harmful type of cell death in liver cells. When these microscopic plastic pieces enter liver cells, they activate a specific pathway that causes the cells to essentially self-destruct, which could potentially damage the liver over time. This research helps explain how the plastic pollution we're exposed to daily might be harming our bodies, particularly our liver health.
These findings indicate that PS-NPs promote hepatocyte pyroptosis through the YAP1-cGAS-STING pathway, with YAP1 serving as a central regulator, providing mechanistic insight into PS-NPs-induced liver toxicity and identifying YAP1 as a potential therapeutic target.

Polystyrene microplastics exposure aggravates acute liver injury by promoting Kupffer cell pyroptosis
Researchers found that long-term exposure to polystyrene microplastics worsened acute liver injury in mice by triggering a specific type of inflammatory cell death called pyroptosis in liver immune cells. When they blocked this cell death pathway either genetically or with a drug, the damaging effects of the microplastics were significantly reduced. The study suggests that microplastic exposure may make the liver more vulnerable to injury by amplifying inflammatory responses.
Activation of pyroptosis and ferroptosis is involved in the hepatotoxicity induced by polystyrene microplastics in mice
Researchers exposed mice to polystyrene microplastics and found that the particles caused significant liver damage, including structural changes and impaired function. The study identified two specific cell death pathways, pyroptosis and ferroptosis, as key mechanisms driving the liver injury. These findings suggest that microplastic exposure may harm liver health through multiple biological pathways that warrant further investigation.
Accumulation of polystyrene microplastics induces liver fibrosis by activating cGAS/STING pathway
Researchers found that tiny polystyrene microplastics (0.1 micrometers) can enter liver cells and cause DNA damage that triggers a chain reaction leading to liver scarring, known as fibrosis. The microplastics activated a specific immune signaling pathway called cGAS/STING, which caused inflammation that progressively damaged liver tissue even at low concentrations. This study reveals a specific mechanism by which long-term microplastic exposure could lead to serious liver disease in humans.
Acute exposure to polystyrene nanoparticles promotes liver injury by inducing mitochondrial ROS-dependent necroptosis and augmenting macrophage-hepatocyte crosstalk
Researchers discovered that very small polystyrene nanoparticles (20 nanometers) cause liver damage in mice by accumulating inside immune cells called macrophages, disrupting their energy-producing structures (mitochondria), and triggering a form of cell death that then spreads damage to liver cells. This study reveals a specific mechanism by which nanoplastic exposure could harm the liver, an organ critical for filtering toxins from the body.
The size-dependence and reversibility of polystyrene nanoplastics-induced hepatic pyroptosis in mice through TXNIP/NLRP3/GSDMD pathway
Researchers exposed mice to environmentally relevant doses of polystyrene nanoplastics of two different sizes and found that both triggered inflammatory cell death in liver tissue. The smaller particles (100 nm) caused more severe effects than the larger ones (500 nm), working through a specific inflammatory pathway. Importantly, the study found that this liver damage was reversible after exposure stopped, with inflammation returning to near-normal levels after a 50-day recovery period.
