Overview

Our service provides a comprehensive suite of assays to evaluate the impact of test compounds on key fungal virulence factors. By targeting these factors, researchers can develop compounds that don't directly kill the fungus but instead disarm it, making it susceptible to the host's immune system or other therapies. This approach can reduce the selective pressure for resistance development, a major challenge in antifungal drug discovery.

Standard Assays

Biofilm Inhibition Assay: Quantifies the anti-biofilm activity of a compound using crystal violet staining and metabolic activity assays (e.g., XTT, resazurin).
Adhesion Inhibition Assay: Measures the ability of a compound to prevent fungal cells from adhering to a substrate, typically a microtiter plate or host cell line.
Enzyme Activity Assay: Colorimetric or fluorometric assays to assess the inhibition of key hydrolytic enzymes (e.g., Sap proteins, phospholipases).
Germ Tube Formation Assay: Evaluates the inhibition of the yeast-to-hyphal transition in pathogenic fungi like Candida albicans.

Customizable Services

We can tailor our assays to meet your specific research needs, including:

Screening against specific fungal strains, including clinical isolates and drug-resistant strains.
Assessing virulence factors under different environmental conditions (e.g., varying pH, temperature, nutrient availability).
High-throughput screening (HTS) of large compound libraries.
Combinatorial drug testing to identify synergistic effects.

Sample Information

Test Compounds: Minimum of 1 mg of each compound, with detailed information on solubility and stability.
Fungal Strains: We can use our in-house strains, or you can provide your own. Please ensure strains are properly stored and shipped with all relevant safety information.

Mechanism of Action

Fungal virulence is a complex process mediated by several key factors. Our assays focus on inhibiting these factors rather than the fungus itself. Here's how it works:

Fungal Adhesion Inhibition: Assays measure the ability of a test compound to prevent the fungus from adhering to host cells or surfaces. Adhesion is the critical first step in colonization and infection.
Biofilm Formation Disruption: We screen for compounds that inhibit the formation of biofilms—complex microbial communities encased in an extracellular matrix. Biofilms are highly resistant to antifungal drugs and host immune responses.
Hydrolytic Enzyme Activity: Our service includes assays to measure the inhibition of secreted enzymes like proteases, lipases, and phospholipases, which degrade host tissues and facilitate fungal invasion.
Efflux Pump Modulation: We evaluate compounds for their ability to inhibit efflux pumps. These pumps are a key mechanism of antifungal resistance, actively expelling drugs from fungal cells.
Morphological Transition Inhibition: Many pathogenic fungi switch between different forms (e.g., yeast-to-hyphal transition) to invade tissues. We offer assays to identify compounds that block this transition, effectively neutralizing their invasive potential.

FAQs

What fungal species do you work with?

We have extensive experience with a wide range of pathogenic fungi, including Candida species, Aspergillus fumigatus, Cryptococcus neoformans, and various dermatophytes. We can also work with other species upon request.

Can you perform assays on my specific clinical isolate?

Yes, we can. We follow strict biosafety protocols and require detailed information on the isolate before accepting it.

What are the target customer groups for this service?

This service is ideal for biotechnology and pharmaceutical companies, academic research institutions, and agricultural science companies involved in the discovery and development of new antifungal agents.

Why is it necessary to target virulence factors?

Targeting virulence factors can circumvent the problem of drug resistance. By disarming the fungus instead of killing it, you reduce the selective pressure for resistance, potentially leading to more durable therapies. Additionally, this approach can be synergistic with existing antifungals.
