There is likely a curation function of neural tissue towards microbes in the gut via the brain -> vagus nerve and neurons in the gut. Autoimmune disease at least partially involves dysregulated microbe curation/infection with pathogens.

Fecal microbiota transplants induce behavioral and physiological changes in mice, and this is likely to occur in humans as well. Gut microbes produce neurotransmitters and communicate back and forth with the brain - hence the phrase "trust your gut".

Fascinating idea. How would we observe the difference? First thought: we’d see that immune mechanisms for suppressing microorganisms were more selective and more discriminate than they “needed” to be, in comparison to alternative mechanisms that seemed equally easy to evolve.

And, 2nd, we’d see that beneficial microorganisms were more likely to be supported in some way by the immune system, showing an adaptive link between “benefits from the immune system” and “benefits the individual”. And this pattern might hold differently across environments.

Let’s find an immune toothpaste, one that farms caries-eating bacteria.
