Figure Lengend Snippet: (A–F) Immunohistochemistry technique for capturing SNPH intrusion in PC dendrites. Shown is SNPH (green), Syt2 (red), and Calbindin (blue) labeling in 3.5-month-old WT (A, C, and E) and Shi (B, D, and F) mice. Scale bar, 10 μm. (G and H) High magnification of the maximum intensity projection image from the z stack through dendritic regions of WT (G) and Shi (H). (I and J) Orthogonal (slice) view of SNPH punctum (indicated by arrows in panels G and H) in the dendritic region from WT (I) and Shi (J) in x-z and y-z orientations, respectively. (K) Quantification of percentage area occupied by SNPH within the dendritic volume from 3 mice of each group. Data are shown as mean ± SEM. *p < 0.05. (L–N) Capturing SNPH intrusion by pre-tagging dendritic mitochondria in vivo using viral transduction. (L) Technique to selectively transduce PCs with AAV-Mito-mCherry. (M) Demonstration of successful pre-tagging of mitochondria in dendrites of a single PC by Calbindin staining. Scale bar, 10 μm. (N) Demonstration of how pre-tagged dendritic mitochondria in PCs are used to capture SNPH intrusion by 3D rotation. (O and P) Single dendritic tree in WT (O) or Shi (P) pre-tagged with Mito-mCherry (red) and SNPH intrusion (green) captured by co-rotation with Mito-mCherry. Merged images show the fraction of dendritic mitochondria anchored by intruded SNPH (yellow). (Q and R) Percentage of PCs with SNPH intrusions (Q) and percentage of SNPH bound to mitochondria per dendritic tree (R) from WT (n = 73) and Shi (n = 106) PCs. Data are shown as mean ± SEM. ***p < 0.005.

Figure Lengend Snippet: (A and B) Representative images of lentivirally transduced GFP-SNPH (1–469) (A) and GFP-SNPH (B) in PCs of SNPH-KO mice injected with saline (no harmaline, vehicle only). (C-H) Effect of harmaline on GFP-SNPH (1–469)-transduced (C) and GFP-SNPH-transduced (F) PC dendrites. Degenerating dendrites in GFP-SNPH-transduced PCs can be seen in (F). Also shown is Calbindin labeling of GFP SNPH (1–469) (D) and GFP-SNPH (G) from (C) and (F). Merged images of GFP SNPH (1–469) and GFP-SNPH with Calbindin are shown in (E) and (H), respectively. (I–K) Representative image of a harmaline-induced degenerating PC (white arrow in I) transduced with GFP-SNPH. Calbindin staining from the same section is shown in (J), whereas a merged image is shown in (K). Scale bars, 20 μm. (L) Quantification of dendritic shrinkage in GFP-SNPH (1–469)- and GFP-SNPH-transduced PCs in the absence (n = 3 mice, vehicle only) or presence of harmaline (n = 5 mice). Data are shown as mean ± SEM. ***p < 0.001.

Article Title: Persistent pain intensifies recall of consolidated fear memories

doi: 10.1016/j.ynstr.2019.100163

Figure Lengend Snippet: Ongoing pain induced morphological changes in the BLA interneuronal population. Panels A and B show calbindin immunoreactivity (Calb-ir, green) and panels D and E show parvalbumin immunoreactivity (Parv-ir, red) expression in sham mice ( A and D ) and in cuffed mice ( B and E ). Panels G and H show the combined expression of the two markers in sham ( G ) and cuffed ( H ) mice, where the Calb/Parv-ir co-localization appears as yellow. The number of Calb-ir cells did not differ between the groups ( C) but the number of Parv immunopositive neurons increased in the cuffed mice ( F ) and most of these Parv-ir neurons were colocalized with Calb-ir, or the yellow labeled neurons in the G and H inserts; The graph in panel I compares the number of Calb/Parv-ir neurons of sham and cuffed mice. The cell counts were evaluated by T-test, * p < 0.05 and *** p < 0.001, bars represent mean ± SEM, n = 12 to 14 per group. BLA - basolateral amygdala, CeA - central amygdala, LA - lateral amygdala. Scale bar = 200 μm. (For interpretation of the references to colour in this figure legend, the reader is referred to the Web version of this article.)

Article Snippet: A similar immunostaining protocol was used for visualization of calbindin and parvalbumin in the BLA using rabbit anti-calbindin D28 antibody (Synaptic Systems, Goettingen, Germany) diluted 1:10 K and monoclonal mouse antibody against parvalbumin (Sawnt, Marly, Switzerland) diluted 1:5 K. The next step was incubation with secondary anti-rabbit Alexa 488 and anti-mouse Alexa 594 antibodies (Jackson ImmunoResearch Inc. West Grove, PA) for 4 h at room temperature.

Figure Lengend Snippet: FIGURE 1 Subsets of axon tracts are missing or misrouted in the cTKO brain. A-F, L1 labeling in coronal (A-D) and axial (E-F) sections of E17.5 brains. The internal capsule (arrow) is present in control (A,E) but not cTKO (B,F) brains. An ectopic “U-shaped” bundle projects into the hypothalamus of cTKO brains (open arrowheads, B). The corpus callosum (arrows) and anterior commissure (closed arrowheads) both cross the midline in control (C,E) and cTKO (D,F) brains. G,H, Immunohistochemistry for calbindin in E15.5 brain sections labels a population of axons in the cortical wall of control brains (open arrowheads, G), which are missing from cTKO cortices (asterisks, H). I-R, E15.5 cortices labeled with L1 and Tag1. L1- and Tag1-positive axons are present in control (I-L) and cTKO (N-Q) cortices. L1-positive axons are reduced in cTKO cortices (M); however, Tag1-positive axons are similar between genotypes (R). A population of L1-positive/ Tag1-negative axons is present in control brains (open arrowheads, J-L), but missing in cTKO brains (asterisks, O-Q). AC, anterior commissure; Ctx, cortex; CC, corpus callosum; IC, internal capsule, Thalamus; Tel, telencephalon; Di, diencephalon.
