Abstract:
Background
Most neurodegenerative and other brain disorders, especially Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and autism spectrum disorder (ASD) continue to elude objective biomarkers and effective treatments. Increasing evidence indicates that such diseases involve focal inflammation of the brain.

Objective
To review the role of cytokine-neuropeptide interactions in the pathogenesis of inflammation of the brain and the beneficial role of natural flavonoids.

Method
Medline search was conducted (2000-2017) for articles using the terms allergy, amygdala, atopy, autism, brain, chemokines, cytokines, hypothalamus, immunity, inflammation, mast cells, microglia, neurotensin, peptides, substance P, TNF.

Results
Neuropeptides and cytokine stimulation of mast cells and microglia can results in focal inflammation in the hypothalamus and amygdala, thus explaining most of the symptoms at leass in ME/CFS and ASD. Some of the triggers may be corticotropin-releasing hormone (CRH), neurotensin (NT), and substance P (SP), which has synergistic action with IL-33. The natural flavonoids luteolin and tetramethoxyluteolin inhibit these processes and have neuroprotective actions. Tetramethoxyluteolin is also more metabolically stable and has greater oral absorption.

Conclusion
Inhibition of inflammatory processes unique to the brain with intranasal formulations of tetramethoxyluteolin could provide new possibilities for the understanding and treatment of neurodegenerative diseases.
