Fig. 5. Phospho-acetylation of histone H3 after stimulation of DA, mACh and GLU receptors. IHC was performed using (from top to bottom) anti-P.H3 (P), anti-Ac14.H3 (Ac14), anti-Ac9.H3 (Ac9), anti-Ac9/14.H3 (Ac9/14), anti-P-Ac9.H3 (P-Ac9) and anti-P-Ac14.H3 (P-Ac14) antibodies on cryosections obtained from mice treated as in Fig. 1B. (A) High magnifications of the DG revealed with all these antibodies. (B) High magnifications of the CA1, CA2 and CA3 regions revealed with anti-P-Ac14.H3 (P-Ac14) antibody. Scale bar, 15 µM.
