Figure Lengend Snippet: NM-LP TK /RSV-MnCDs alleviates discogenic pain in IVDD. (A) Experimental timeline schematic. (B–C) Open-field behavioral analysis showing locomotor activity parameters (active time, central mean speed, total distance, and mean speed) across groups (n = 5). (D–E) PWL and PWT test showing alleviation of thermal and mechanical allodynia by NM-LP TK /RSV-MnCDs in LSI mice (n = 5). (F–G) IHC staining and quantification analyses of DRG sections showing expression of sensory neuropeptides CGRP and SP (n = 5). Scale bar, 100 μm. (H–I) IF co-labeling of PGP9.5 and CGRP/SP in DRG, and corresponding quantification analyses (n = 5). Scale bar, 100 μm. Data are presented as mean ± SD. For comparisons among multiple groups at a single time point, one-way ANOVA followed was employed to determine statistical significance. For datasets involving multiple groups evaluated over time, including PWL and PWT assessments, a two-way repeated measures ANOVA was utilized. ∗, P < 0.05; ∗∗, P < 0.01; ∗∗∗, P < 0.001; ∗∗∗∗, P < 0.0001; ns = not significant.
Article Snippet: For immunofluorescence (IF) staining, antigen retrieval was conducted using citrate buffer (0.1 M, pH 6.0), followed by blocking in 10 % normal goat serum (Solarbio, Cat. No. SL038) at room temperature for 1 h. Sections were incubated overnight at 4 °C with primary antibodies targeting ACAN (Cat. No. DF7561, Affinity), COL2A1 (Cat. No. AF0135, Affinity), MMP3 (Cat. No. AF0217, Affinity), MMP13 (Cat. No. 18165-1-AP, Proteintech), CD31 (Cat. No. AF0077, Affinity), p-LATS1 (Cat. No. AF7170, Affinity), p-YAP (Cat. No. AF3328, Affinity), Tuj1 (Cat. No. 66375, Proteintech), CGRP (Cat. No. DF7386, Affinity), SP (Cat. No. DF7522, Affinity), and PGP9.5 (Cat. No. AF5490, Affinity) followed by incubation with appropriate fluorescent secondary antibodies for 2 h at room temperature and counterstaining with DAPI (Beyotime, Cat. No. C1006).
