Intravital Microscopy for Atherosclerosis Research

Area of Science:

• Cardiovascular Research
• Medical Imaging
• Immunology

Background:

• Leukocyte recruitment into arteries is central to atherosclerosis development and a key therapeutic target.
• Understanding the molecular mechanisms of arterial leukocyte infiltration necessitates high-resolution, real-time visualization.

Purpose of the Study:

• To review optical imaging modalities for in vivo visualization of leukocyte recruitment in experimental atherosclerosis models.
• To discuss strategies for overcoming challenges in arterial imaging and highlight advanced labeling techniques.

Main Methods:

• Overview of optical imaging techniques applicable to mouse models of atherosclerosis.
• Discussion of methods for non-toxic, photostable labeling of target structures.
• Exploration of emerging technologies like superresolution microscopy and opto-acoustic microscopy.

Main Results:

• Optical imaging allows in vivo display of leukocyte recruitment processes in large arteries.
• Strategies exist to overcome hurdles inherent to arterial imaging.
• Novel labeling approaches and advanced microscopy enhance visualization capabilities.

Conclusions:

• Advanced optical imaging and labeling techniques are crucial for studying leukocyte recruitment in atherosclerosis.
• Emerging technologies promise improved resolution and reduced toxicity for in vivo arterial imaging.
• This review provides a foundation for future research into atherosclerosis mechanisms and therapeutic targeting.
