Fig. 6From: Plasma neurofilament light chain and amyloid-β are associated with the kynurenine pathway metabolites in preclinical Alzheimer’s diseaseCorrelations between KP metabolites and Aβ40 (a) and Aβ42 (b) species in participants with high NAL. Plasma Aβ40 correlated with the kynurenine to tryptophan ratio (K/T) and other kynurenine pathway (KP) metabolites, namely kynurenine (KYN), kynurenic acid (KA), anthranilic acid (AA), and quinolinic acid (QA) using Pearson’s correlation coefficient. Plasma Aβ42 correlated with the kynurenine to tryptophan ratio (K/T) and other kynurenine pathway (KP) metabolites, namely kynurenine (KYN), kynurenic acid (KA), anthranilic acid (AA), and quinolinic acid (QA) using Pearson’s correlation coefficient. Log transformed plasma Aβ and KP analyte concentrations have been presentedBack to article page
