Paraffin-embedded brains were sliced into 5 µm sections on positively charged slides for serotonin (S-2A) receptors, ionized calcium-binding adaptor (Iba-1) and doublecortin (DCX) immunohistochemistry. The following primary antibodies; (# sc-32538, Santa Cruz Biotechnology, Dallas, TX, USA) in concentration 1:100, (# sc-32725, Santa Cruz Biotechnology, Dallas, TX, USA) in concentration 200 µg/mL and (# sc-271390, Santa Cruz Biotechnology, Dallas, TX, USA) in concentration 1:400, respectively, were used. Protocol for IHC was performed as described by Schacht and Kern [18 (link)] for S-2A receptors, Farrag et al. [19 (link)] for Iba-1 and Sirerol-Piquer et al. [20 (link)] for DCX. The quantitative analysis of immunoreactive parts percentage (IRP%) was implemented using Image J software. Seven random microscopic fields per slide were subjected to analysis after subtraction of light background.
