Imaging-assisted nanoimmunotherapy for atherosclerosis in multiple species

Area of Science:

• Nanomedicine
• Immunotherapy
• Cardiovascular Research

Background:

• Limited clinical translation of nanomedicine formulations despite extensive research.
• Murine models show limited predictive value for human efficacy in nanomedicine.
• Need for improved scale-up and evaluation strategies for nanoimmunotherapies.

Purpose of the Study:

• To scale up a nanoimmunotherapy from mouse models to large animal models (rabbits and pigs).
• To address production and evaluation challenges in translational nanoimmunotherapy research.
• To assess the anti-inflammatory efficacy and plaque progression effects of nanoimmunotherapy in atherosclerosis.

Main Methods:

• Scale-up of nanoimmunotherapy production from small to large animal models.
• Integration of translational imaging readouts for in vivo behavior analysis and treatment response assessment.
• Evaluation of nanoimmunotherapy efficacy in mouse, rabbit, and porcine atherosclerosis models.

Main Results:

• Nanoimmunotherapy demonstrated anti-inflammatory efficacy in mice, rabbits, and pigs.
• The nanoimmunotherapy successfully halted atherosclerosis plaque progression in large animal models.
• Integrated translational imaging facilitated in vivo assessment in larger species.

Conclusions:

• The developed nanoimmunotherapy is translatable across species, from mice to large animals.
• The approach shows potential for acute treatment of atherosclerosis by reducing inflammation and halting plaque progression.
• Integrated imaging is crucial for evaluating nanoimmunotherapy in translational studies.
