Imaging Neuroinflammation - from Bench to Bedside.

Area of Science:

• Neuroscience
• Medical Imaging
• Immunology

Background:

• Neuroinflammation is a key factor in many neurological disorders, including Alzheimer's disease and stroke.
• The inflammatory process in the brain, while aimed at repair, can cause significant tissue damage under pathological conditions.
• Early identification and quantification of neuroinflammation are critical for timely therapeutic intervention.

Purpose of the Study:

• This review focuses on molecular imaging techniques for visualizing and quantifying neuroinflammation.
• The review highlights agents targeting inflammatory cells and molecules with high translational potential.
• Emphasis is placed on methods applicable to neurological diseases like stroke, multiple sclerosis, and Alzheimer's disease.

Main Methods:

• Discussion of advanced molecular imaging modalities including MRI, PET, SPECT, and optical imaging.
• Overview of imaging agents designed to visualize endothelial cell activation via adhesion molecules.
• Exploration of techniques to assess leukocyte functions (e.g., oxidative stress, phagocytosis) and cell tracking.
• Mention of methods for in vivo targeting of specific cell types and quantifying disease consequences like neuronal death and demyelination.

Main Results:

• Numerous molecular imaging agents have been developed and tested in preclinical models of neuroinflammation.
• Several promising agents have successfully transitioned from laboratory research to clinical application.
• Molecular imaging enables visualization of cellular activation, leukocyte function, and disease progression in the central nervous system.

Conclusions:

• Molecular imaging provides powerful tools for understanding and monitoring neuroinflammation.
• Translating novel imaging agents from bench to bedside is essential for advancing neurological disease management.
• Increased investment and research efforts are needed to accelerate the clinical adoption of these technologies.
