A significant difference in 5HT2A receptor protein levels was observed in the sgACC between groups F(2, 34) = 3.858, p = 0.019, with significantly lower 5HT2A observed in DLB cases overall (p = 0.026) and in DLB cases with depression compared to controls (p = 0.044), but not when comparing DLB donors with or without depression directly (p = 0.590, Mann-Whitney U; Fig. 5G–L). The gene discussed is HTR2A; the disease is major depressive disorder.
