ObjectiveIncreased plasma kynurenine has been reported in tic disorder patients, and this observation has been suggested to be indicative of immune dysregulation. In the present study, we examined plasma levels of kynurenine and related molecules in a group of tic disorder patients.MethodsPlasma concentrations of tryptophan, kynurenine, cortisol, and neopterin were determined in Dutch tic disorder patients (N = 59), and healthy volunteers (N = 32). Group means were compared and age-controlled… 
Altered monocyte activation markers in Tourette’s syndrome: a case–control study
TLDR
It is found that CRP and neopterin levels and the number of monocytes were significantly higher in TS patients than in healthy controls and a monocyte dysregulation in TS could predispose to infections or autoimmune reactions.
Immune Dysfunction in Tourette Syndrome
TLDR
Lymphocyte subpopulation analysis in TS suggests a possible systemic activation of several T- and B-cell subtypes, whereas the observed decreased numbers of T regulatory lymphocytes might predispose to autoimmunity.
The Modulating Role of Stress in the Onset and Course of Tourette’s Syndrome
TLDR
A functional relationship between stress and tic disorders has been suggested, and it is suggested that dopaminergic and noradrenergic neurotransmission as well as immunology play a crucial role in mediating this relationship.
Immunopathogenic mechanisms in tourette syndrome: A critical review
TLDR
A pathophysiological model is proposed to explain the possible effect of immunity upon dopamine transmission regulation and the generation of tics, and a general predisposition to autoimmune responses in TS patients is indicated by the reduced frequency of regulatory T cells, which induce tolerance towards self‐antigens.
The role of immune mechanisms in Tourette syndrome
Tryptophan Catabolites and Their Impact on Multiple Sclerosis Progression.
TLDR
This review is an attempt to address any relevant association between dysregulation of KP and multiple sclerosis (MS), an inflammatory CNS disorder that ultimately leads to demyelinated brain areas and severe neurological deficits.
The Relationship between Tourette’s Syndrome and Infections
TLDR
A deeper insight into the precise mechanism of how infectious agents influence immune parameter, tryptophan metabo-lism and the resulting neurotransmitter availability could help finding new therapeutic strategies.
Association between intracellular infectious agents and Tourette’s syndrome
TLDR
Within the Tourette’s syndrome patients a higher rate of antibody titers could be demonstrated, pointing to a possible role of Chlamydia and Toxoplasma in the pathogenesis of tic disorders.
What Does Immunology Have to Do With Normal Brain Development and the Pathophysiology Underlying Tourette Syndrome and Related Neuropsychiatric Disorders?
TLDR
The past decade's literature is reviewed and a critical commentary on the involvement of immunological mechanisms in normal brain development, as well as its role in the pathophysiology of Tourette syndrome, other Chronic tic disorders, and related neuropsychiatric disorders including Obsessive-compulsive disorder (OCD) and Attention deficit hyperactivity disorder (ADHD).
The immunobiology of Tourette's disorder, pediatric autoimmune neuropsychiatric disorders associated with Streptococcus, and related disorders: a way forward.
TLDR
Evidence regarding the immunobiology as well as the relevant clinical and therapeutic aspects of TD, OCD, and PANDAS are explored, considering the overlap of clinical and neuroanatomic findings among these disorders.

Increased plasma kynurenine and its relationship to neopterin and tryptophan in Tourette's syndrome.
TLDR
Values for tryptophan, neopterin and tetrahydrobiopterin were similar in TS patients and controls, but in patients with Gilles de la Tourette syndrome only, there was a significant negative correlation between tryPTophan and neopter in and a significant positive correlation between kynurenine and nepterin when controlling for trypsin.
Blood serotonin and tryptophan in Tourette syndrome.

TLDR
The low blood serotonin and tryptophan levels in TS are consistent with the wide range of behavioral disorders seen in TS and suggest tryPTophan oxygenase as a possible candidate gene.
Inter-relationships between quinolinic acid, neuroactive kynurenines, neopterin and beta 2-microglobulin in cerebrospinal fluid and serum of HIV-1-infected patients.
TLDR
It is concluded that immune activation increases the levels of neuroactive kynurenines within the central nervous system of HIV-1-infected patients secondary to activation of indoleamine-2,3-dioxygenase.
Kynurenine potentiates the DOI head shake in mice
TLDR
It has been suggested that tic-like movements such as head shakes, which occur in rodents after a wide variety of pharmacological challenges, may model the tics observed in GTS (Handley and Dursun, 1992).

Increased Antistreptococcal Antibody Titers and Anti—Basal Ganglia Antibodies in Patients With Tourette Syndrome: Controlled Cross-Sectional Study
TLDR
The results support the reported association between streptococcal infection and anti-basal ganglia antibodies and some patients with Tourette syndrome.
Preliminary findings of antistreptococcal antibody titers and basal ganglia volumes in tic, obsessive-compulsive, and attention deficit/hyperactivity disorders.
TLDR
The findings suggest that the prior reports of an association between antistreptococcal antibodies and either CTD or OCD may have been confounded by the presence of ADHD and support the hypothesis that in susceptible persons who have ADHD or OCD, chronic or recurrent streptococal infections are associated with structural alterations in basal ganglia nuclei.
