Figure Lengend Snippet: Analyses of two prior single-cell RNA-seq studies of mouse DRG neurons reveal widespread expression of NaV1.6 across both A- and C-fiber afferents , . (A) Violin plots showing NaV1.6 (Scn8a) mRNA expression levels across distinct DRG neuronal populations. NF, neurofilament; NP, non-peptidergic; PEP, peptidergic; TH, tyrosine hydroxylase. (B) Violin plot showing NaV1.6 mRNA expression in colonic DRG neurons. RPM, reads per million; TPM, transcripts per million.

Article Snippet: Tissue sections were incubated with rabbit antibodies against NaV1.6 (1:1000, Alomone) and co-stained with rat antibodies against GFP (1:1000, MBL International Corp) for 24 h at 4 °C, and then incubated with a mixture of secondary antibodies Alexa Fluor® 594-conjugated anti-rabbit IgG (1:200, Abcam) and Alexa Fluor® 488-conjugated anti-rat IgG (1:200, Abcam) for 2 h at room temperature.

Figure Lengend Snippet: Both large- and small-diameter DRG neurons show clustering of NaV1.6 in stem axons near the somata. (A) Representative DRG sections co-stained for NaV1.6 (red) and afferents (green) showing NaV1.6 clusters (indicated by white arrow heads) in the stem axon of both large- and small-diameter neurons. Scale bar: 20 μm. (B) Distance between the somata and the first NaV1.6 clustering in the stem axon. There was no significant difference between the large- and small-diameter groups (t-test, p = 0.58).

Figure Lengend Snippet: NaV1.6 clustering is present in A-fiber axons but absent in C-fiber axons of the sciatic nerve. (A) Representative immunostaining of NaV1.6 in sciatic nerve sections with sparsely labeled afferents following intrathecal AAV9 injection. Arrowheads indicate the presence of NaV1.6 clusters in Aβ- (Φ > 4.5 μm) and Aδ-fiber axons (1.5 μm < Φ < 4.5 μm), but not in C-fiber axons (Φ < 1.5 μm). (B) NaV1.6 cluster density (clusters per 100 μm) is significantly higher in Aβ-fiber axons than in Aδ-fiber axons (mean ± SEM; t test, p = 0.003). Scale bar: 10 μm.

Figure Lengend Snippet: NaV1.6 clustering in afferent nerve endings in the bladder. (A-B) Immunostaining of bladder tissue sections from VGLUT2/tdTomato mice showed the presence of NaV1.6 clustering, in some bladder afferent axons (putative nerve terminals) as indicated by white arow heads. (C–D) Non-terminal axons of bladder afferents lack detectable NaV1.6 staining. Scale bar: 20 μm.

Figure Lengend Snippet: NEURON simulation of ePNS and DRG stimulation of a C-fiber afferent. (A) Action potentials evoked by DRG stimulation initiates close to the soma and propagates bi-directionally to both peripheral and central axons. (B) Action potentials evoked by ePNS of the peripheral axon propagates to soma and central axon. (C) The clustering of NaV1.6 in the stem axon strongly decreased the threshold of DRG stimulation to evoke APs. In contrast, comparable increases in NaV1.8 conductance within the clustering zone had no effect on the threshold, whereas increases in NaV1.7 conductance produced only a modest reduction. (D) Spatial plot along the soma and stem axon to reveal the site of spike initiation at the NaV1.6 clustering zone. Five spatial membrane voltage traces have 0.05 msec intervals (from 1 to 5).
