Figure Legend Snippet: a A representative macroscopic current time-course (top panel) recorded from a HEK-293T cell expressing rat TRPV1 in response to the temperature ramp (10–50 °C) at a membrane potential of −60 mV and then followed by a saturating concentration of RTx (50 nM) and 20 µM ruthenium red (RR). The dashed line indicates zero current. The recorded temperature is shown in the middle panel. The Arrhenius plot for the temperature activation was shown in the bottom panel. Fitted Q 10 values for high (blue line) and low (red line) temperature ranges are shown. A representative time-course recording for RTx-bound TRPV1 temperature sensitivity. First the channel was challenged by 10 nM RTx for ~20 s followed by a temperature ramp (10–48 °C), then a saturating concentration of RTx (50 nM) was introduced, and finally RR (20 µM) was applied to completely block the channel.

Fitted Q 10 values for high and low temperature (T) ranges are shown. c Q 10 values as a function of I/I 50nM RTx for low and high temperature ranges. Each experiment was conducted as shown in a and . The low T range Q 10 value is steady at 1.7, while the high T range Q 10 rapidly collapses from ~38 to ~3.

Journal: Molecular Pain
doi: 10.1177/1744806916656846

Figure Legend Snippet: Phenotypic changes in prostatic acid phosphatase (PAP)(+) dorsal root ganglion neurons in resiniferatoxin (RTX)-induced neuropathy. (a–e) Double immunofluorescence staining was performed with anti-activating transcription factor 3 (ATF3; a–e in red) and anti-PAP (a–e in green) antisera in the vehicle (a), RTX (b), 4-methylcatechol (4MC) (c), NGF (RTX + 2.5S NGF; d), and (e) abNGF (4MC + anti-NGF antisera) groups. (f–h) The graphs quantify the density changes in (f) PAP(+) and (g) ATF3(+) neurons and (h) the ratio changes in ATF3(+)/PAP(+) neurons according to Panels (a) to (e). (i) The mechanical thresholds were assessed using the up-and-down method with von Frey monofilaments, as described in the Materials and Methods. The graph indicates the changes in the mechanical thresholds in the vehicle (open bar), RTX (filled bar), 4MC (grey bar), NGF (slashed bar), and abNGF (dotted bar) groups. (j, k) The graphs indicate that the mechanical thresholds correlated with PAP expression, that is, a linear correlation with (j) PAP densities and (k) an inverse correlation with the ratio of ATF3(+)/PAP(+) neurons. (l, m) The graphs show the diameter histogram of ATF3(+)/PAP(+) neurons in the RTX (l) and 4MC (M) groups. The diameter histogram shows no difference between the RTX and 4MC groups, but higher numbers of ATF3(+)/PAP(+) neurons in the RTX group. Bar, 50 µm. * p < 0.05, ** p < 0.01, *** p < 0.001.
Techniques Used: Double Immunofluorescence Staining, Expressing

Figure Legend Snippet: Colocalization of prostatic acid phosphatase (PAP) and high-affinity nerve growth factor (trkA) receptor after resiniferatoxin (RTX)-induced neuropathy. (a–j) Double immunofluorescence staining of dorsal root ganglia sections was performed with anti-PAP (a–e) and trkA (f-j) in the vehicle (a, f), RTX (b, g), 4-methylcatechol (4MC; c, h), (d, i) NGF (RTX + 2.5S NGF), and (e, j) abNGF (4MC + anti-NGF antisera) groups. (k, l) The graphs show the changes in (k) trkA density and (l) the colocalized ratios of PAP(+)/trkA(+) neurons in the vehicle (open bar), RTX (filled bar), 4MC (grey bar), NGF (slashed bar), and abNGF groups (dotted bar) according to Panels (a) to (j). (m) The graph shows that the mechanical thresholds correlate linearly with the ratios of PAP(+)/trkA(+) neurons. Bar, 50 µm. * p < 0.05, ** p < 0.01.

Figure Legend Snippet: Diagram of prostatic acid phosphatase (PAP) pathology modulates the pain perception in resiniferatoxin (RTX) neuropathy. This diagram illustrates the PAP pathology mediating pain development follows a NGF-trkA-dependent manner, as described in the following steps: (1) RTX sensitizes the transient receptor potential vanilloid subtype 1 (TRPV1). (2) RTX then induces activating transcription factor 3 (ATF3) upregulation on PAP(+) neurons, indicating the PAP pathology. (3) The PAP pathology reduces the AMP hydrolysis. (4) This reduction evokes pain perception because of the decrease in the adenosine analgesic effect. (5) Nerve growth factor (NGF) binds to high-affinity NGF receptor (trkA) and (6) reverses the induction of the ATF3 and PAP pathology. (7) This recovers the PAP-mediated analgesic effect by returning the ability of AMP hydrolysis.
