Most administered nanoparticles accumulate in the liver, reducing therapeutic efficacy and increasing toxicity. This review explores nanoparticle-liver interactions and strategies to overcome liver sequestration for improved nanomedicine translation.
Area of Science:
- Biomedical Engineering
- Nanotechnology
- Hepatology
Background:
- Nanoparticle administration often results in significant accumulation (30-99%) in the liver.
- This hepatic sequestration limits drug delivery to target tissues and can cause cellular toxicity.
- Understanding nanoparticle-liver interactions is crucial for advancing nanomedicine.
Purpose of the Study:
- To review nanoparticle-hepatic cell interactions.
- To examine nanoparticle elimination via the hepatobiliary system.
- To discuss strategies for mitigating liver sequestration of nanoparticles.
Main Methods:
- Literature review of inter- and intra-cellular nanoparticle-hepatic cell interactions.
- Analysis of nanoparticle elimination mechanisms in the hepatobiliary system.
- Synthesis of current strategies to manipulate nanoparticle liver sequestration.
Main Results:
- High liver accumulation of nanoparticles is a common challenge.
- Hepatic sequestration impacts therapeutic targeting and safety.
- Various strategies exist to modulate nanoparticle behavior in the liver.
Conclusions:
- Addressing nanoparticle-liver interactions is essential for clinical translation.
- Effective management of liver sequestration will enhance nanomedicine applications.
- Overcoming hepatic challenges is key for nanodiagnostics and nanotherapeutics.
