Malassezia-derived Exosome Research & Application
Overview Workflow Research Highlights Key Advantages Testimonials FAQs
The genus Malassezia represents a group of lipid-dependent fungi that inhabit human and animal skin. Among them, Malassezia sympodialis is a dominant commensal species known for its dynamic interaction with the host's epidermal barrier and immune system. In recent years, Malassezia-derived exosomes have gained attention for their roles in fungal–host communication, immune modulation, and skin microenvironment regulation.
Creative Biolabs, with years of expertise in microbial exosome research, provides high-quality customized production and analytical services for Malassezia-derived exosomes.

Standard Workflow for Malassezia-Derived Exosome Preparation
Creative Biolabs' standardized Malassezia exosome development workflow focuses on reproducibility and high-quality vesicle yield. While our standard workflow includes customized production and basic purification, advanced characterization and component profiling are offered as optional services depending on the available strain library and research scope.
Stepwise Workflow
-
Fungal Cultivation
Inoculate Malassezia sympodialis on modified Dixon agar and incubate at 30 °C for 48–72 h.
After 3–4 passages, transfer selected colonies into liquid modified Dixon medium.
Incubate overnight with gentle agitation to promote vesicle release.
-
Pre-Isolation Purification
Remove fungal cells, debris, and large vesicular aggregates through sequential differential centrifugation.
Ensure each centrifugation step is optimized for size-based separation to maintain vesicle integrity.
Collect clarified supernatant containing extracellular vesicles.
-
Concentration and Filtration
Use ultrafiltration to concentrate the supernatant and minimize soluble impurities.
Perform membrane filtration to exclude particles above the exosome size range.
Retain concentrated filtrate for ultracentrifugation.
-
Ultracentrifugation and Exosome Recovery
Perform successive ultracentrifugation cycles to pellet Malassezia-derived exosomes.
Carefully resuspend the exosome pellet in sterile cold PBS buffer to maintain structural integrity.
Store the final product under controlled conditions to prevent degradation.

KEY FINDINGS AND OUTCOMES
|
|
Cellular uptake and distribution
|
Confocal imaging demonstrated that Malassezia-derived exosomes were internalized by keratinocytes and accumulated near perinuclear regions over time, without inducing cell toxicity.
|
|
Regulation of pro-inflammatory cytokines
|
qPCR and ELISA data indicated strong induction of IL-6 in keratinocytes following exosome exposure, consistent with enhanced signaling in epithelial immune response.
|
|
In vivo cytokine response validation
|
Immunohistochemical staining in mouse models confirmed IL-6 upregulation in epidermal layers exposed to Malassezia-derived exosomes, suggesting their role in skin inflammation.
|
|
Activation of NF-κB pathway
|
Western blot analysis revealed increased phosphorylation of p65 subunit after treatment, confirming NF-κB pathway activation; this effect was reduced by NF-κB inhibition.
|
|
ICAM-1 expression modulation
|
Confocal microscopy of primary keratinocytes showed markedly higher ICAM-1 expression after Malassezia exosome treatment compared with control samples.
