Although GAD65/67 protein expression was 30.05% and 36.73% lower in the midbrain in the high inflammatory and low inflammatory/schizophrenia subgroups, respectively, compared to controls, this did not reach statistical significance overall when analysed by inflammatory subgroup (F(2,46) = 2.895, p = 0.065) (Table 3). This evidence concerns the gene GAD2 and schizophrenia.
