In this study, we investigated the activation of TRPV1 and TRPA1 by N-acyl homoserine lactones, quorum sensing molecules produced by Gram-negative bacteria, and the inhibitory effect of TRPV1 and TRPA1 by autoinducing peptides (AIPs), quorum sensing molecules produced by Gram-positive bacteria, using human embryonic kidney 293T cell lines stably expressing human TRPV1 and TRPA1, respectively. As a result, we found that some N-acyl homoserine lactones, such as N-octanoyl-L-homoserine lactone (C8-HSL), N-nonanoyl-L-homoserine lactone (C9-HSL) and N-decanoyl-L-homoserine lactone (C10-HSL), activated both TRPV1 and TRPA1. In addition, we clarified that some N-acyl homoserine lactones, such as N-3-oxo-dodecanoyl-L-homoserine lactone (3-oxo-C12-HSL), only activated TRPV1 and N-acyl homoserine lactones having saturated short acyl chain, such as N-acetyl-L-homoserine lactone (C2-HSL) and N-butyryl-L-homoserine lactone (C4-HSL), only activated TRPA1. Furthermore, we found that an AIP, simple linear peptide CHWPR, inhibited both TRPV1 and TRPA1 and peptide having thiolactone ring DICNAYF, the thiolactone ring were formed between C3 to F7, strongly inhibited only the TRPV1. Although the specificity of TRPV1 and TRPA1 for quorum sensing molecules was different, these data suggest that both TRPV1 and TRPA1 would function as receptors for quorum sensing molecule produced by bacteria.

人类 TRPV1 和 TRPA1 是细菌群体感应分子的受体

在这项研究中,我们研究了 N-酰基高丝氨酸内酯、革兰氏阴性菌产生的群体感应分子对 TRPV1 和 TRPA1 的激活,以及革兰氏阴性菌产生的群体感应分子自诱导肽 (AIP) 对 TRPV1 和 TRPA1 的抑制作用。阳性菌,分别使用稳定表达人 TRPV1 和 TRPA1 的人胚肾 293T 细胞系。结果,我们发现了一些 N-酰基高丝氨酸内酯,例如 N-辛酰基-L-高丝氨酸内酯 (C8-HSL)、N-壬酰基-L-高丝氨酸内酯 (C9-HSL) 和 N-癸酰基-L-高丝氨酸内酯 (C10-HSL) 激活 TRPV1 和 TRPA1。此外,我们澄清了一些 N-酰基高丝氨酸内酯,如 N-3-氧代-十二烷酰基-L-高丝氨酸内酯 (3-oxo-C12-HSL),仅激活 TRPV1 和具有饱和短酰基的 N-酰基高丝氨酸内酯链,例如 N-乙酰基-L-高丝氨酸内酯 (C2-HSL) 和 N-丁酰基-L-高丝氨酸内酯 (C4-HSL),仅激活 TRPA1。此外,我们发现AIP,简单的线性肽CHWPR,抑制TRPV1和TRPA1和具有硫代内酯环DICNAYF的肽,硫代内酯环在C3到F7之间形成,仅强烈抑制TRPV1。尽管 TRPV1 和 TRPA1 对群体感应分子的特异性不同,但这些数据表明 TRPV1 和 TRPA1 都可以作为细菌产生的群体感应分子的受体。仅强烈抑制TRPV1。尽管 TRPV1 和 TRPA1 对群体感应分子的特异性不同,但这些数据表明 TRPV1 和 TRPA1 都可以作为细菌产生的群体感应分子的受体。仅强烈抑制TRPV1。尽管 TRPV1 和 TRPA1 对群体感应分子的特异性不同,但这些数据表明 TRPV1 和 TRPA1 都可以作为细菌产生的群体感应分子的受体。
