This study found that in baby mice, certain friendly bacteria in the gut make a chemical called serotonin. This chemical helps the baby mice's immune systems accept both the good bacteria and the foods they eat without attacking them. Normally, our bodies can mistakenly see food or good bacteria as invaders, leading to allergies or other immune problems. The researchers discovered that this serotonin from gut bacteria teaches special immune cells to be more accepting, preventing such mistakes. This is especially important in early life when the immune system is still learning what to ignore and what to fight against. So, in a nutshell, the good bacteria in baby mice's guts are helping to train their immune systems to not overreact to things that are actually harmless, using serotonin as a teaching tool.
The gut microbiome is coming out as linked to so much more in the body that we ever imagined previously. My theory is that I got RA due to depression and horrible diet (because doctors can't exactly tell). Lack of serotonin threw the immune system off.
Seperately, issues with dopamine change how the brain perceives and flags pain signals. In someone with a deficiency and suffering from chronic pain the two are linked.
Yes I think this pattern will get much clearer in the near future. We already see these links with chronic illness, depression, etc and gut dysbiosis. One thing I wouldn’t count out is the effect of lingering virus or viral antigens causing regular immune system stimulation leading to various unexplained illnesses to varying degrees. They also can contribute heavily to gut dysbiosis which may be linked with serotonin production and other things. Knowing how bacteria plays together is one thing but we also need to understand how pathogens can affect our guts as well!
Yeah, low grade infection persisting was also a possibility. As well as dysregulation from nicotine/alcohol/cannabis overuse and lack of meaningful reliable social interaction. The full college experience in short. Up to that point I thought the most likely and dangerous ailments were from acute injury (which I was deft at avoiding during risky thrill-seeking behavior). But I believe I had it completely backwards.
I appreciate it. I'm thankful the lifestyle guidelines are improving in adoption rates and quality. What I mean is that more and more diet and exercise (and meditation) are as key as any highly successful targeted drug. The idea is to do all simultaneously. https://en.wikipedia.org/wiki/Biopsychosocial_model?wprov=sf...
There are studies (multi-generational long-term) telling us that positive/meaningful social experience is one of if not the greatest factor in affecting healthspan.
this is behind kombucha being marketed as a "health product" - the establishment of a the right amount of cognitive dissonance so that one day, a guy walks into a bar and orders a 6% kombucha in order to feel like he just went to the gym
