Recent research into ME/CFS investigates increased kynurenine production rather than decreased levels proposed by the metabolic trap hypothesis. The balance between tryptophan depletion and kynurenine generation, marked by the kynurenine and tryptophan (KYN/TRP) ratio, indicates IDO activity and immune responses

This scenario might be considered analogous to that of oxidative stress, which occurs when ROS production chronically exceeds the levels at which it exerts beneficial effects

below the endogenous AtGCL concentration in plastids, which was estimated to be in the micromolar range

Germline testing results confirm an LS diagnosis [46,47], whereas, if MLH1 is methylated in a tumor, a complementary MLH1 methylation study in blood should be performed to identify constitutional epimutation of MLH1 [48] (Figure 2)
