therapeutic action: Itraconazole antifungal activity

Overexpression of efflux pump and biofilm associated genes in itraconazole resistant Candida albicans isolates causing onychomycosis

mycolabadmin

This research examines why some fungal infections of the nails resist treatment with the antifungal drug itraconazole. Scientists found that resistant fungi produce more proteins that pump the drug out of their cells (efflux pumps) and form protective biofilm structures. Understanding these resistance mechanisms could help develop better combination treatments that work alongside antifungal drugs to overcome resistance.

Overexpression of efflux pump and biofilm associated genes in itraconazole resistant Candida albicans isolates causing onychomycosis

Nail fungal infections caused by Candida albicans can be difficult to treat when the fungus becomes resistant to common antifungal medications like itraconazole. Researchers found that resistant strains have overactive genes that pump the drug out of fungal cells and genes that help the fungus form protective biofilm structures. Understanding these resistance mechanisms could lead to better combination treatments that block these protective strategies.

Overexpression of efflux pump and biofilm associated genes in itraconazole resistant Candida albicans isolates causing onychomycosis

This study examined why some fungal nail infections caused by Candida albicans don’t respond to itraconazole treatment. Researchers found that resistant fungi have higher levels of genes that pump the antifungal drug out of their cells and genes that help them form protective biofilm layers. These findings suggest that combining itraconazole with drugs that block these pumps or disrupt biofilms could be more effective for treating stubborn fungal nail infections.

Itraconazole resistance in Madurella fahalii linked to a distinct homolog of the gene encoding cytochrome P450 14-α sterol demethylase (CYP51)

mycolabadmin

A fungal infection called mycetoma caused by Madurella fahalii doesn’t respond to a common antifungal drug called itraconazole. Researchers discovered that this fungus has an extra gene that produces a protein that resists the drug, which isn’t found in a similar fungus that remains susceptible. This finding could help develop better treatments for mycetoma patients in the future.
