Fighting Fungal Infections |

THURSDAY, March 11 (HealthDayNews) -- A protease-inhibitor cocktail increases the anti-microbial action of promising new peptides that kill several medically important fungi, some of which are resistant to current drugs, says a University at Buffalo study.
The cocktail protects the peptides by inactivating enzymes programmed to destroy the peptides. This protection lets the peptides more than double their anti-microbial activity, the study found.
The findings were presented March 11 at the International Association of Dental Research meeting in Hawaii.
One peptide in particular, MUC7 12-mer, has shown particular promise for treating drug-resistant fungi. This peptide is a piece of a larger, naturally occurring human salivary mucin molecule.
The researchers note there are only a handful of drugs available to treat fungal infections. The advent of drug-resistant fungal infections poses a special risk to people with depressed immune systems, including those with HIV/AIDS, and organ-transplant and chemotherapy patients.
