Perturbation of physiological systems by nanoparticles

Area of Science:

• Nanomedicine and Toxicology
• Biocompatibility and Risk Assessment

Background:

• Societal adoption of nanotechnology is hindered by safety concerns regarding human exposure to nanoparticles.
• Nanoparticles can enter the body through multiple routes and distribute to various organs via circulation.
• Understanding nanoparticle interactions with biological systems is crucial for assessing health risks.

Purpose of the Study:

• To comprehensively review the health risks associated with nanoparticle exposure.
• To examine how nanoparticles perturb various physiological systems based on animal studies.
• To emphasize the potential toxicity to physiological systems and the consequences of disrupted homeostasis.

Main Methods:

• Literature review of animal studies on nanoparticle exposure and health effects.
• Analysis of nanoparticle entry routes, distribution, and elimination within the body.
• Examination of cellular and systemic responses to nanoparticle interactions.

Main Results:

• Nanoparticles interact with biological molecules, potentially disturbing cell signaling and physiological functions.
• Some nanoparticles are eliminated, while others persist in the body, posing long-term risks.
• Disruption of physiological systems can lead to impaired organ function and pathological disorders.

Conclusions:

• Nanoparticle exposure presents significant health risks across multiple physiological systems.
• Perturbation of homeostasis by nanoparticles can result in adverse health outcomes.
• Further research is needed to fully understand and mitigate nanoparticle toxicity for safe application.
