|
Reaction Conditions |
0.1-10µM Resiniferatoxin; 24 hours |
|

Resiniferatoxin (RTX), an ultrapotent capsaicin analog, is a vanilloid agonist that binds to the transient receptor potential channel, vanilloid subfamily member 1 (TRPV1).Resiniferatoxin activates TRPV1 in an irreversible manner. It also can bind and activate members of the PKC family[1-4].
Resiniferatoxin(0.1-10µM; 24 hours) can induce G0/G1 arrest in non-transformed intestinal epithelial cells[4].
Resiniferatoxin (250ng,50µL;s.c) blocks inflammatory heat hyperalgesia when applied directly to the sciatic nerve in a time and dose dependent fashion[5]. Resiniferatoxin treatment increased serum levels of IL-4, IL-10 and IL-13, and it decreases intestinal eosinophilia, however, favours the mastocytosis, promoting T spiralis intestinal expulsion[6]. Cutaneous injection of Resiniferatoxin(100 µL of RTX 0.002% (2 g); s.c in the plantar skin) completely alleviates and prevents nerve-injury-induced neuropathic pain in rat[7].

Resiniferatoxin (RTX)是一种超强辣椒素类似物,是一种结合瞬时受体电位通道,香草蛋白亚家族成员1 (TRPV1)的香草蛋白激动剂。Resiniferatoxin以不可逆的方式激活TRPV1,它还可以结合和激活PKC家族的成员[1-4]。
Resiniferatoxin(0.1 -10µM;24 h)可诱导未转化肠上皮细胞G0/G1阻滞[4]。
Resiniferatoxin (250ng,50µL;s.c)直接作用于坐骨神经时,可阻断炎症性热痛觉过敏,且具有时间和剂量依赖性[5]。Resiniferatoxin治疗可提高血清IL-4、IL-10和IL-13水平,减少肠道嗜酸性粒细胞,但有利于肥大细胞增生,促进螺旋T虫肠道排出[6]。皮下注射Resiniferatoxin (100µL RTX 0.002% (2 g); s.c in the plantar skin)完全缓解和预防大鼠神经损伤性神经性疼痛[7]。
