The kynurenic pathway. The kynurenic pathway. The encircled metabolites were measured and symbols indicate method and biological sample, that is, LC-MS/MS detection in plasma, NMR detection in urine and GC-MS detection in plasma. Our results comparing SLE and controls are represented by a hyphen if no change in metabolite level and an upward pointing arrow if the metabolite level was increased in SLE. Our hypothesis for a possible role of the kynurenic pathway in the pathogenesis of SLE is illustrated by dashed arrows.
