Candidalysin
Based on 1 Customer Validation
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

Biological Activity
Candidalysin (3-70 μM, 2 h) induces phosphorylation of EGFR at Y1068 and Y845 in TR146 cells in a dose-dependent manner[1].
Candidalysin (3-70 μM, 2 h-24 h) induces immune response in TR146 cells that are mediated by MMP and calcium influx[1].
Candidalysin (1.5-70 μM, 24 h) induces the release of LDH in A431 vaginal epithelial cells in a dose-dependent manner[2].
Candidalysin (1.5-70 μM, 24 h) upregulates the expression levels of proinflammatory cytokines IL-1α, IL-1β, G-CSF, GM-CSF, IL-6 and IL-8 secreted by A431 vaginal epithelial cells[2].
Candidalysin (10-50 μM, 2 h) activates NLRP3 inflammasome and specifically stimulates bone marrow-derived macrophages (BMDM) to secrete IL-1β[3].

Candidalysin (wild-type C. albicans infection) (5×108 cfu/ml, Intravaginally inoculated, once) induces neutrophil recruitment and mucosal damage in the vulvovaginal candidiasis (VVC) mouse model[2].
MedChemExpress (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.

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (0.76 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
