Pericytes: Problems and Promises for CNS Repair.

Area of Science:

• Vascular biology
• Neuroscience
• Regenerative medicine

Background:

• Microvascular complications cause progressive organ damage.
• Pericytes regulate microcirculation, blood-brain barrier (BBB) function, and homeostasis.
• Pericytes are increasingly recognized for their role in various diseases.

Purpose of the Study:

• To review the multifaceted roles of pericytes in health and disease.
• To explore pericyte involvement in angiogenesis, BBB function, neuroinflammation, fibrosis, and neurodegeneration.
• To discuss therapeutic strategies targeting pericytes for CNS repair and axon regeneration.

Main Methods:

• Literature review of pericyte function and disease involvement.
• Analysis of pericyte roles in specific physiological and pathological processes.
• Synthesis of current knowledge on pericyte-targeted therapies.

Main Results:

• Pericytes are vital for microvascular integrity and function.
• Dysfunctional pericytes contribute to BBB breakdown, neuroinflammation, and neurodegeneration.
• Pericytes influence fibrosis and hinder axon regeneration after CNS injury.
• Evidence suggests pericytes are key players in microvascular complications.

Conclusions:

• Pericytes are critical regulators of CNS homeostasis and repair.
• Targeting pericyte behavior presents promising therapeutic avenues for neurological disorders.
• Further research into pericyte manipulation is essential for advancing CNS regenerative strategies.
