Carnitine transport and fatty acid oxidation
These include genes encoding catalase, peroxiredoxin, thioredoxin and thioredoxin reductase, a glutaredoxin-related protein, rubredoxin and rubrerythrin, a homolog for the peroxide stress protein YaaA 69 , and an arginase, which, through its catabolism of L-arginine, is hypothesized to limit this amino acid for the host synthesis of nitric oxide, a compound involved in host defense and host immune responses 35
In short, the gut microbiota influences brain function via the regulation of neurotransmitters and neurotrophic factors, maintenance of intestinal barrier and tight junction integrity, activation of enteric sensory afferents, production of bacterial metabolites, and modulation of mucosal immune responses [22]
