Candidalysin 是一种由真菌白色念珠菌 (Candida albicans) 分泌的溶细胞肽毒素。Candidalysin 可通过激活 EGFR-MAPK 信号通路,诱导 MMP 表达和钙离子内流,并分别通过 p38 MAPKERK1/2 调控 c-Fos 转录因子与 MKP1,从而驱动上皮免疫应答。Candidalysin 对于粘膜和全身感染至关重要,可激活 NLRP3 促发炎症反应、中性粒细胞募集及 Th17 免疫。Candidalysin 可激活 LDH 导致膜损伤而表现出细胞毒性。

生物活性

Candidalysin is a cytolytic peptide toxin secreted by the fungus Candida albicans. Candidalysin drives epithelial immune responses by activating the EGFR-MAPK signaling pathway, inducing MMP expression and calcium influx, and regulating the c-Fos transcription factor and MKP1 via p38 MAPK and ERK1/2 respectively. Candidalysin is essential for mucosal and systemic infections, activating NLRP3 to promote inflammatory responses, neutrophil recruitment, and Th17 immunity. Candidalysin activates LDH causing membrane damage and exhibiting cytotoxicity[1][2][3][4]

Candidalysin (3-70 μM, 2 h-24 h) 诱导 TR146 细胞的免疫反应需要 MMP 和钙离子内流介导[1]
Candidalysin (1.5-70 μM, 24 h) 以剂量依赖性方式诱导 A431 阴道上皮细胞 LDH 的释放[2]
Candidalysin (1.5-70 μM, 24 h) 上调 A431 阴道上皮细胞分泌的促炎细胞因子 IL-1α、IL-1β、G-CSF、GM-CSF、IL-6 和 IL-8 表达水平[2]
Candidalysin (10-50 μM, 2 h) 激活 NLRP3 炎性小体特异性激发骨髓来源巨噬细胞 (BMDM) 分泌 IL-1β[3]

体内研究
(In Vivo)

Candidalysin (野生型 C. albicans 感染) (107 cfu/mL,舌下含服 75 分钟,1 次) 可诱导口咽念珠菌病 (OPC) 模型的小鼠舌组织中的 pEGFR Y1068 磷酸化[1]
Candidalysin (野生型 C. albicans 感染) (5×108 cfu/ml,阴道接种,1 次) 可诱导外阴阴道念珠菌病 (VVC) 小鼠模型中中性粒细胞募集和粘膜损伤[2]

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Murine OPC model (female Balb/c mice 22-25 g)[1]
Dosage: 107 cfu/ml C. albicans yeast culture
Administration: Sub-lingually for 75 min, once
Result: Compared with those lacking the candidalysin parent gene ECE1 (ece1Δ/Δ) or the candidalysin-encoding region (ece1Δ/Δ+ECE1Δ184-279), wild-type (WT) C. albicans infection induced lower levels of pEGFR Y1068 in tongue tissues.
Animal Model: Murine VVC model (female 6-8 weeks old C57BL/6 mice)[2]
Dosage: 5×108 cfu/ml C. albicans, 10 μL of the standardized blastoconidial cell suspension, generating an inoculum size of 5×106 blastoconidia.
Administration: Intravaginally inoculated, once
Result: Increased fungal burden.
Increased LDH activity.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
