Disbalance of kynurenines produced by Drosophila mutations of the kynurenine pathway of tryptophan metabolism influences the locomotor behavior in larvae. The most pronounced is the effect of accumulation of kynurenic acid in the mutant cinnabar manifested as sharp reduction of general level of locomotor activity. The mutations seem to act through modulatory influences of kynurenines on signal cascades governed by ionotropic glutamatergic and cholinergic receptors. Expression of receptor genes in the mutants shows age-related changes pointing to gradual evolvement of consequences of kynurenines disbalance.
