cytokines in the blood stream
What does the gut activation of neural afferent circuits of the brain activate?
-of mucosal immune response
and produce metabolites that can travel via the blood stream to the brain
-all of these are
influenced by the health and activity of the microbiome.
How is the microbiome involved in metbaolism tryotphan?

- Pharmaceuticals
- Stress (exercise, metabolic, psychological)
- Infant feeding method
- Birthing process
- Lifecycle stages
- Geography
- Physical activity
- Illness and disease
