| Caption | Hippocampal disorganization, increased c-fos, and loss of SOM+ interneurons in Dcxtm1Caw/Y Dclk2tm1.2Jgg/Dclk2tm1.2Jgg (Dcx -/y ; Dclk2 -/-) mice. (A and B) DAPI-stained P18 coronal hippocampus in control delineate densely packed GCL (g.c.l.) in the dentate gyrus (D.G.) and pyramidal layer (p.l.) in the CA field. In the mutants the p.l. is delaminated in CA3 (arrow) and CA1 (arrowheads). The g.c.l. is also less packed and consequently thicker (Insets, compare brackets); n = 4. (C-F) Mutant pyramidal neurons show higher levels and more c-fos-positive cells than controls in both CA2/3 (arrows in C and E) and CA1 (arrowheads in D and F) fields at P18; n = 2. (G-J) SOM+ interneurons in both the D.G. hilus and the strata oriens (s.o.) of the CA region. Mutants show reduced number of SOM+ interneurons (30.44 +/- 7.48 vs. 64.56 +/- 6.74; P = 0.0276; n = 3 mice each), both in the D.G. (5.00 +/- 0.51 vs. 16.22 +/- 2.47; P = 0.0113), and in s.o. (15.89 +/- 5.73 vs. 40.78 +/- 4.64; P = 0.0279) (H and I). Remaining SOM+ interneurons express the same level of SOM (Inset in G and H). No significant difference in the total number of Parv+ (30.67 +/- 1.67 in mutants vs. 36.33 +/- 6.33 in controls; n = 2 mice of each genotype) or CaBP+ (63.15 +/- 14.58 in mutants vs. 59.44 +/- 7.99 in controls; n = 3 mice each); s.r., strata radiata; l.m., lacunosum moleculare. Dashed line delineates the hippocampal fissure. [Scale bars, 400 um (A, B, G, and H); 110 um (C-F).] | ||||||
