Indoleamine-2,3-dioxygenase (IDO) is an enzyme that catabolises tryptophan - an essential amino acid critical for T cell proliferation. Initially recognized as a first line of host defense against infectious pathogens, IDO has been subsequently identified as an important immune-regulator inhibiting

A recent study--comparing those with depression, somatization, comorbid depression+somatization, and controls--showed specific changes in the tryptophan catabolite (TRYCAT) pathway in somatization, specifically lowered tryptophan and kynurenic acid, and increased kynurenine/kynurenic acid (KY/KA) and kynurenine/tryptophan ratios. These findings suggest that somatization
