- DC. (), the sole official species in the 2025 Chinese Pharmacopoeia, is a subtropical woody vine endemic to southern China. Its traditional ethnomedicinal uses for pain, inflammation, and metabolic disorders are supported by modern extraction technologies-ultrasonic-assisted extraction (UAE), microwave-assisted extraction (MAE), flash extraction, and enzymatic hydrolysis-that enhance the recovery of bioactive constituents. Phytochemical profiling reveals over 60 pentacyclic triterpenoid saponins, phenylpropanoids, flavonoid glycosides, and acidic polysaccharides. Pharmacological mechanisms include COX-2 inhibition, TRPV1 blockade, and ASIC3 downregulation for analgesia and anti-inflammation; AMPK/IRS-1 pathway activation for antitumor and metabolic effects; enhancement of superoxide dismutase (SOD) activity for antioxidant activity; and Bax/Bcl-2 modulation for hepatoprotection. Food applications include enzyme-assisted juice, fermented vinegar, clarified wine, and spray-dried powders. This review synthesises botany, phytochemistry, pharmacology, and processing innovations, highlighting its commercial potential and proposing metabolomic strategies for discovering novel bioactive compounds to accelerate its integration into nutraceutical and medicinal formulations. - Source: PubMed

Chang Chen-YuWang Xiao-YunLiu Ke-JiaLi QiLu Shu-YanMa Qin-GeWei Rong-Rui - Acid-sensing ion channel 3 (ASIC3), a proton-gated cation channel predominantly expressed in primary afferent nociceptors, is an acidosis-related pain generator. Previous experiments suggested that ASIC3 is also involved in the generation of itch. However, mechanistic links between ASIC3 and itch, including the expression of ASIC3 in itch-mediating primary sensory neurons, remain unclear. We examined ASIC3 expression in these sensory neurons and then investigated whether mild acid stimulation could induce ASIC3-dependent itch without overt pain in mice. - Source: PubMed

Shibata YasuhiroChaya RyosukeYokoi YutoKumamoto NatsukoUeda TakashiYousif Elamin Yousif ZobidahFujihara YoshitakaIkawa MasahitoYasui TakahiroUgawa Shinya - Cytokine interleukin-33 (IL-33) signaling in primary sensory neurons plays a crucial role in pain. However, the underlying molecular mechanisms remain poorly understood. Therefore, we investigated whether IL-33 signaling affects ion channels in nociceptive dorsal root ganglion (DRG) neurons. Herein, we reported that the application of IL-33 enhanced the electrophysiological activity of acid-sensing ion channels (ASICs). IL-33 dose-dependently increased acid-evoked ASIC currents in mouse DRG neurons. IL-33 enhanced the maximum responses of ASICs, whereas the sensitivity to acidic stimuli remained unaffected. This IL-33-induced enhancement of ASIC currents was dependent on suppression of the tumorigenicity 2 (ST2) receptors. The enhancing effect of IL-33 on ASIC currents was prevented by the p38 mitogen-activated protein kinase inhibitor SB202190, but not by the ERK inhibitor U0126 or the JNK inhibitor SP600125, indicating the effect was p38-dependent. Moreover, IL-33 potentiated the action potentials triggered by acidic stimuli. Finally, ASIC3-deficient mice displayed attenuated mechanical hyperalgesia induced by intraplantar or intramuscular injection of IL-33. Our findings revealed that IL-33 enhanced ASIC function via ST2 and the intracellular p38 signaling pathway, which might provide a promising therapeutic approach for pain treatment by targeting IL-33/ST2 signaling. - Source: PubMed

Liu Ting-TingLi Xue-MeiQiu Chun-YuHu Wang-Ping - Leukotriene B4 (LTB4) is a lipid mediator generated from arachidonic acid. Studies have shown that LTB4 plays a role in the pain process. However, little is known about the underlying molecular and cellular mechanisms. The present data demonstrated a functional link between LTB4 and acid-sensing ion channels (ASICs) in mouse dorsal root ganglion (DRG) neurons. LTB4 potentiated acid-activated ASIC currents in a concentration-dependent and pH-independent manner. The potentiating effect of LTB4 on ASIC currents was mediated by BLT1 receptors but not by BLT2 receptors. The LTB4-induced potentiation of ASIC currents was prevented by the ERK1/2 inhibitor U0126 and the JNK inhibitor SP600125, but not by the p38 inhibitor SB202190, indicating involvement of intracellular ERK1/2 and JNK signaling. Moreover, LTB4 potentiated the burst of action potentials evoked by acidic stimuli in mouse DRG neurons. Behaviorally, intraplantar injection of LTB4 exaggerated spontaneous nociceptive behaviours evoked by subsequent acid challenge in WT mice, and developed attenuated mechanical hyperalgesia in ASIC3 KO mice. Our results suggested that LTB4 potentiated the electrophysiological activity of ASICs via BLT1 receptors as well as the ERK1/2 and JNK signaling pathways, which might open promising new perspectives for pain treatment associated with tissue acidification. - Source: PubMed

Sun FeiYuan HuanWang ChenDu BeibeiLi Xue-MeiLiu Ting-TingQiu Chun-YuHu Wang-Ping - Acid-sensing ion channels (ASICs) are proton-gated sodium channels encoded by four genes in mammals. The ASIC3 isoform is widely expressed and plays a critical role in pain signaling and inflammatory responses. Despite a high degree of sequence homology between rat and human ASIC3 orthologs, they exhibit pronounced functional differences. Notably, rat ASIC3 undergoes steady-state desensitization (SSD) at extracellular pH values of 7.1-7.0, whereas human ASIC3 is largely desensitized at physiological pH (7.4-7.3), underscoring substantial interspecies divergence with important translational implications. In this study, we systematically investigated the functional properties of rat and human ASIC3 channels using concatemeric constructs that enable precise control over subunit stoichiometry and gene order within engineered trimeric assemblies. Using whole-cell electrophysiology, we show that homomeric concatemeric channels (r-r-r and h-h-h) closely recapitulate the biophysical properties of their respective wild-type channels. Substitution of a single subunit at the N-terminal position of the concatemer with an ASIC3 ortholog produced minimal functional perturbations and yielded channel properties most similar to those of the corresponding homomeric channel. In contrast, replacement of the C-terminal subunit resulted in the most pronounced shifts in pHSSD values and significant alterations in activation kinetics and current characteristics, indicating that functional properties of ASIC3 concatemers are strongly influenced by subunit position within the construct. Together, these findings demonstrate that both subunit composition and positional arrangement contribute to the functional behavior of engineered ASIC3 concatemers and provide a useful experimental framework for analyzing interspecies differences between rat and human ASIC3 channels. The results also highlight important limitations of concatemeric approaches, including the potential emergence of non-native channel properties in certain construct configurations. - Source: PubMed
