The purpose of this protocol is to collect serum zonulin levels in people with schizophrenia. This one time visit will collect zonulin levels, antibodies to gliadin (tissue transglutaminase and antigliadin antibodies) and other information that may relate to increased intracellular tight junction permeability as it related to the immune and stress system and the immune association with kynurenic acid pathway 50. Data will be collected for use in future grant applications and published reports.

Zonulin concentration in serum (ng/mg)
Participants will undergo a one-time blood draw in order to test for zonulin concentration in serum (ng/mg) and these results will be compared to normative data to screen for elevations. The sample size for this pilot study was estimated based on the known prevalence of Celiac disease in schizophrenia, a disease known to have elevated zonulin levels.
