Longitudinal study of beta2-microglobulin abnormalities in schizophrenia.

In an earlier cross-sectional study, we reported antipsychotic-naive schizophrenia patients to have significantly elevated beta2-microglobulin (beta2M) level suggestive of its potential association with the pathogenesis of schizophrenia. In this study, we present the follow-up analyses of beta2M in 31 patients from the previous study who were re-assessed after 92.1+/-7.

Beta2-microglobulin abnormalities in antipsychotic-naïve schizophrenia: evidence for immune pathogenesis.

Studies examining immune dysfunction in schizophrenia have reported decreased type-1 T-helper cell specific immunity (Th1) and increased type-2 T-helper cell specific immunity (Th2) and related abnormalities in inflammatory system. Beta2-Microglobulin (beta2M) influences the development of dendritic cells, which play a significant role in regulating the differentiation of naive CD4+ T cells into Th1 or Th2 lineages. The present study examined serum beta2M in antipsychotic-naïve schizophrenia patients (n=43) in comparison with age, sex, handedness and socioeconomic status matched healthy controls (n=43).
