Lasioglossins LLIII affect the morphogenesis of Candida albicans and reduces the duration of experimental vaginal candidiasis in mice.

Lasioglossins are a group of peptides with identified antimicrobial activity. The inhibitory effects of two synthetic lasioglossin derivatives, LLIII and D-isomeric variant LLIII-D, on morphological changes in Candida albicans in vitro and the effect of local administration of LLIII during experimental murine candidiasis were investigated.

Exposition of dermatophyte Trichophyton mentagrophytes to L-cystine induces expression and activation of cysteine dioxygenase.

Cysteine dioxygenase (CDO) is involved in regulation of intracellular cysteine levels by catabolising the cysteine to sulphite and sulphate. In keratinolytic fungi, sulphite is actively excreted to reduce disulphide bridges in keratin before its enzymatic degradation. The pathogenicity role of CDO was confirmed in cysteine-hypersensitive and growth-defective ΔCdo mutant of Arthroderma benhamiae on hair and nails.
