Lactoferrin is a natural killer of Candida spp.

Lactoferrin is an iron-binding protein in milk. It plays an important role in the host defense system as it prevents microbes from
growing and forming biofilms. In addition to antimicrobial activity, lactoferrin exhibits some anticancer activities. Lactoferricin
(Lfcin) and lactoferrampin (Lfampin), which are peptides derived from lactoferrin, demonstrated antimicrobial activity with
promising prospects and are currently one of the research focuses. We investigated the antifungal effect of these two peptides. We
found that fungal cells exposed to Lfcin manifested morphological alterations, changes in plasma membrane permeability and
mitochondrial membrane potential and ROS accumulation in cells. Lfcin also suppressed superoxide dismutase 3 (SOD3) expression
in the fungal cells. Lfampin exerted its antifungal effect mainly through induction of necrosis. It also induced changes in plasma
membrane permeability and mitochondrial membrane potential. We also tested the effects of the following combinations (1) Lfcin
and Lfampin (2) The Lfcin and Fluconazole and (3) Lfampin and Fluconazole against Candida spp.
