Results showed a significant increase in Sin3 and HDAC1 levels in HSV-1 infected neurons 24 h p.r. with respect to matched CTRL, whereas no significant changes were detected 24 h after the primary infection (Figure 2a,b; 24 h p.r.: Sin3, * p = 0.017 vs. CTRL; HDAC1, * p = 0.035 vs. CTRL). The gene discussed is HDAC1; the disease is infection.
