IL-8 (CXCL8) Correlations with Psychoneuroimmunological Processes and Neuropsychiatric Conditions.

Area of Science:

• Neuroscience
• Immunology
• Genetics

Background:

• Interleukin-8 (IL-8/CXCL8) is a key chemokine in psychoneuroimmunology.
• IL-8 influences immune cell activation, brain function, neuroprotection, and neuroinflammation.
• Factors like reactive oxygen species (ROS) and CXCL8 gene polymorphisms affect IL-8 production and disease risk.

Purpose of the Study:

• To review the multifaceted roles of IL-8 in neurological and psychiatric health.
• To explore IL-8 as a potential biomarker for neuropsychiatric conditions.
• To highlight implications for personalized medicine.

Main Methods:

• Literature review of studies on IL-8/CXCL8.
• Analysis of IL-8's involvement in immune responses and brain function.
• Examination of IL-8 levels in various biological fluids (blood, CSF, urine).

Main Results:

• IL-8 levels are altered in neuropsychiatric conditions and influenced by stressors.
• IL-8 exhibits dual roles in neuroprotection and neuroinflammation.
• IL-8 is detectable in blood, CSF, and urine, indicating biomarker potential.

Conclusions:

• IL-8 plays a complex role in neuropsychiatric disorders.
• Further research is needed to elucidate IL-8's diverse effects.
• Targeting IL-8 pathways may offer personalized treatment strategies for neurological and psychiatric conditions.
