Figure Lengend Snippet: Coronal brain sections from 8 month-old WT and 5xFAD mice were immunolabeled for Aβ (white fluorescence) and two peptide markers of the SCN-arginine vasopressin (AVP-red fluorescence: Panel A) and vasoactive intestinal peptide (VIP-red fluorescence: Panel B)-and cellular nuclei were labeled with Hoechst (blue fluorescence). In A , high magnification images of the SCN are shown below each whole-brain coronal section. Representative images from 5xFAD tissue reveal marked Aβ-based plaque formation in a number of forebrain structures, including the cortex (CTX); However, plaque deposition was not observed in the SCN. Of note, AVP and VIP expression were indistinguishable between WT and 5xFAD mice, suggesting that the SCN was intact in 5xFAD animals. Bar for the low magnification image: 1000 microns; Bar for the high magnification image in A: 300 microns. C) Dot-blot protein profiling of 5xFAD and WT tissue indicates the presence of Aβ species in both the cortex and SCN of 5xFAD mice. As a control, lysates were also probed for β-actin. Further, the sensitivity of the Aβ antibody was confirmed by probing for recombinant Aβ.

Article Snippet: For fluorescence-based immunolabeling, 44 μm - thick tissue sections were initially permeabilized and blocked with PBS containing 0.02% Triton X-100 (v/v) and 10% bovine serum albumin (w/v) (1 hour), and then treated overnight with a rabbit anti-VIP antibody (1:2,000 dilution; Boster, Catalog code: RP1108) or a rabbit anti-AVP antibody (1:1,000 dilution: Millipore, Catalog code: AB1565).

Article Snippet: After sealing at room temperature for 2 h, tip off the blocking solution, drain the excess water on the filter paper pad, place it flat in the wet box, add 200 μL primary antibody (diluted in the blocking buffer) for VAChT (Synaptic Systems, Germany; cat#139103; 1:500), TH (Cell Signaling Technology, USA; cat#E2L6M; 1:500), CGRP (Cell Signaling Technology, USA; cat#14959; 1:500), VIP (Cell Signaling Technology, USA; cat#63269; 1:500), Ki67 (Cell Signaling Technology, USA; cat#9129; 1:500) and cleaved caspase-3 (Cell Signaling Technology, USA; cat# 9664; 1:500) and incubate at 4 °C for 12 h, and then incubate at room temperature for 4 h. On the second day, the colorectal frozen sections were rinsed with 0.4% PBST three times at room temperature for 10 min each time.
