Molecular imaging of cell death

Area of Science:

• Biomedical imaging
• Radiopharmaceutical science
• Cell biology

Background:

• Apoptosis and necrosis are distinct cell death processes with clinical implications.
• Non-invasive molecular imaging of cell death offers diagnostic and therapeutic monitoring applications.
• Current pre-clinical research explores various imaging approaches for cell death.

Purpose of the Study:

• To review radiopharmaceutical development for apoptosis and necrosis imaging.
• To evaluate in vivo performance of emerging radioligands.
• To highlight clinical applications and future directions in cell death imaging.

Main Methods:

• Review of published literature on apoptosis and necrosis imaging agents.
• Analysis of radiopharmaceutical development and pre-clinical/clinical evaluation.
• Categorization of imaging agents based on cell death type and stage of development.

Main Results:

• Several apoptosis imaging agents ((99m)Tc-Anx, (18)F-ML-10) have reached clinical trials.
• (99m)Tc-glucarate is used for early necrosis imaging, with other agents showing promise.
• Radioligands like (18)F-WC-II-89 require further optimization.

Conclusions:

• Molecular imaging of both apoptosis and necrosis is essential for understanding various pathologies.
• Continued radiopharmaceutical development is needed for accurate cell death assessment.
• Imaging cell death aids in early diagnosis and treatment response monitoring.
