Covalent labeling of immune cells

Area of Science:

• Immunology
• Cell Biology
• Biomedical Imaging

Background:

• Inflammation is a critical innate immune response to tissue damage, essential for healing and organ function.
• The immune system relies on diverse immune cells with specific roles in inflammation.
• Understanding immune cell dynamics requires effective in vivo labeling and imaging techniques.

Purpose of the Study:

• To review current and emerging technologies for immune cell labeling and in vivo imaging.
• To highlight the importance of visualizing immune cell localization, trafficking, and interactions during inflammation.

Main Methods:

• Review of existing literature on covalent cell-type and protein-specific labeling strategies.
• Focus on successful applications of fluorescent reporters and radioactive nuclides for immune cell labeling.
• Exploration of novel technologies with potential for in vivo immune cell imaging.

Main Results:

• Few labeling strategies have been successfully implemented for immune cells despite numerous developed concepts.
• Fluorescent reporters and radioactive nuclides represent established methods for immune cell visualization.
• Emerging technologies show promise for advancing in vivo immune cell labeling and imaging.

Conclusions:

• Effective immune cell labeling is crucial for unraveling inflammation dynamics.
