Candida albicans is a commensal yeast in humans that disseminates in immunocompromised persons. Its spreading is modulated by melanin, hormones, or some neurotransmitters, among other factors. The neurotransmitter gamma-aminobutyric acid (GABA) is used by bacteria, plants, and fungi as a carbon and nitrogen source. In this article, the in vitro effect of different doses of GABA on germ-tube formation and expression of phospholipase B1 (PLB1) mRNA in two Candida albicans strains was investigated. Results demonstrated that GABA increases both germ-tube formation and PLB1 mRNA expression in the two Candida strains in a dose-dependent manner, which suggests that GABA promotes the growth of C. albicans.
