Tryptophan in diet, gut bacteria protect against E. coli infection
Another Key Amino Acid Found in Space: Tryptophan
Amino Acid Tryptophan Detected in Young Star Cluster
A Diet Lacking in Tryptophan Alters Gut Microbiota, Increases Inflammation
With age, insufficient tryptophan alters gut microbiota, increases inflammation
100% of ME/CFS (chronic fatigue syndrome) patients have Genetic Mutation of IDO2. This forces reliance on IDO1 to produce kynurenine from tryptophan. If tryptophan levels in a cell rise too high, then IDO1 will stop making kynurenine & tryptophan levels will remain high. IDO metabolic trap.
