Introduction. Candida albicans is responsible for several types of oral and systemic infections. In light of emerging resistance to antifungals, studies have demonstrated the antifungal effect of lactoferrin (LF), which is part of the innate immune system, has anticandidal activities.Methodology. C. albicans (2×106 c.f.u. ml-1) were incubated either with PBS or human LF (hLF) (100 µg ml-1) at 37 °C for 24 h and then RNA was isolated and virulence factors analysed. C. albicans (1×105 c.f.u.) was injected into the tail vein of immunocompromised wild-type and Ltf-/-. Then, 24 h later, the Ltf-/-I mice received hLF intravenously (100 µg g-1 body weight), while the control group received PBS. Then, 48 h later, the organs were collected, homogenized and C. albicans c.f.u.s were counted. In addition, the inflammatory mediators of kidneys and the virulence factors of C. albicans were analysed.Results. hLF-treated Ltf-/-I mice showed significant clearance of C. albicans in different organ tissues when compared to untreated Ltf-/-I mice. The inflammatory cytokines, such as IL-1β, IL-6, TNF-α and MPO and iNOS were downregulated in hLF-treated Ltf-/-I mice when compared to untreated Ltf-/-I mice. Whereas, IL-10 and IL-17A were upregulated at 72 h post infection when compared to Ltf-/-C mice. Histological analysis also revealed a significant decrease in the size and number of infectious foci in the hLF-treated groups. hLF treatment significantly downregulated several virulence factors of C. albicans both in vitro and in vivo.Conclusion. We concluded that hLF-treated Ltf-/- mice can reduce the severity of C. albicans-induced systemic infection.
