FCGR2B and schizophrenia: In contrast to the robust up-regulation of FcGRT and FcGR3A, FcGR2B gene expression was not different in the midbrain when comparing high-inflammation biotype schizophrenia cases, low-inflammation biotype schizophrenia cases, and control subjects (F(2,53) = 0.65, p = 0.52; Fig. 4d).
