Fig. 6. Acute expression of Npas4 in CA3 reverses short-term and long-term memory deficits observed in Npas4-/- mice.
(A) Expression of Npas4 in CA3 of Npas4-/- mice using HSV-Npas4.
(B) Npas4, but not ΔNpas4, restores expression of c-Fos in vivo.
(C) Expression of Npas4, but not ΔNpas4, drives activity of PIBDNF independent of KCl depolarization. n = 4 cultures. *p ≤ 0.001.
(D) Npas4-/- mice with Npas4 injected into CA3 freeze at similar levels to Npas4+/+ mice injected with GFP 1hr and 24hrs after training. CA1 injection of Npas4 or CA3 injection of ΔNpas4 did not reverse the memory deficit. *p < 0.001.
