Kynurenine is the first stable metabolite of the kynurenine pathway [which metabolises > 9007o of body tryptophan (Wolf, 1974) ]. A number of kynurenine pathway metabolites are known to have biological activity, including 3-hydroxykynurenine, xanthurenic acid, quinolinic acid and kynurenic acid (for reviews, see Schwarcz, 1993; Heyes, 1993; Stone and Connick, 1985). Recent studies have demonstrated that plasma kynurenine concentrations were elevated in all of seven patients suffering from…

The acute studies indicate that head-shakes induced by DOI are indeed inhibited by nicotinic receptor agonists and suggest that this is not a consequence of an increase in kynurenine.

While the observed elevation in plasma neopterin is consistent with immune activation in a subset of tic Disorder patients, metabolism of tryptophan through the kynurenine pathway appears to be unaltered in tic disorder patients.

We provide a review of recent research findings which support the involvement of autoimmunity in childhood-onset tic disorders, in particular the presence of antineuronal autoantibodies, D8/17 B…
Role of Autoimmunity and Infections in Tourette Syndrome

The classically proposed autoimmunity model of TS is analogous to Sydenham’s chorea, and antibodies directed against the streptococci are thought to cross-react with structures of the central nervous system, subsequently leading to damage to these structures, which eventually is thought to result in tics and associated features.

Results strongly support the hypothesis that mediation of mCPP‐induced hypophagia is by stimulation of 5‐HT1C receptors and the mediation of 4‐HT2‐induced head twitches by 5‐ HT2 receptors.

The results indicate that SB 200646A has in vivo efficacy and that 5‐HT2C or 5‐ HT2B receptors are indeed likely to mediate mCPP‐induced hypolocomotion, hypophagia and anxiogenesis and suggest that5‐HT 2C/2B receptor blockade induces anxiolysis.

Of the DOB analogues examined, DOB (1a) possesses optimal selectivity for 5-HT2 binding, and the S-(+) isomer of the iodo analogue of 1a was found to possess one-third the affinity of its R-(-) enantiomer at 5- HT2 sites and also resulted in DOM-stimulus generalization.
