Neuroinflammation and Immune-Brain Interactions
Neuroinflammation represents a critical intersection between the immune system and central nervous system, influencing both neuroprotection and neurodegeneration. Activation of microglia and astrocytes, along with cytokine signaling cascades, contributes to pathological processes in Alzheimer’s disease, multiple sclerosis, traumatic brain injury, and depression. The blood–brain barrier plays a central role in regulating immune cell infiltration and maintaining neural homeostasis. Emerging research highlights bidirectional communication between peripheral immune responses and brain circuits, affecting cognition, mood, and behavior. Advanced molecular profiling techniques are identifying inflammatory biomarkers that predict disease progression and therapeutic response. Novel immunomodulatory therapies aim to reduce harmful inflammation while preserving protective immune functions. Personalized approaches targeting specific inflammatory pathways show promise in clinical trials. Understanding immune-brain dynamics is essential for developing next-generation treatments that balance inflammation control with neural regeneration, ultimately improving long-term neurological outcomes.
