Histatin-5 induces the reversal of Pdr5p mediated fluconazole resistance in Saccharomyces cerevisae

Results revealed that histatin-5 is able to revert MDR phenotype and may be considered a potential alternative MDR inhibitor. Since Pdr5p is homologous to Candida albicans CaCdr1p and CaCdr2p, data obtained might be extrapolated to these transporters, inferring that associating fluconazole and histatin-5 may be a useful tool to circumvent failure treatments of infections caused by Candida MDR strains.
