There were no significant differences in the densities of calretinin-immunoreactive neurons in the lateral (AFF vs. CTR, P = 0.59; SZ vs. CTR, P = 0.61; SZ vs. AFF, P = 0.78), medial (pars fimbrialis and pars intermedia; AFF vs. CTR, P = 1.00; SZ vs. CTR, P = 0.88; SZ vs. AFF, P = 1.00), and dorsal septal nuclei (AFF vs. CTR, P = 0.24; SZ vs. CTR, P = 0.86; SZ vs. AFF, P = 0.22) among patients with schizophrenia, patients with affective disorders, and healthy control subjects (see Figure 2B; Table 2). Here, CALB2 is linked to schizophrenia.
