Abstract
Cryptococcus neoformans infection is a common fungal infection in persons infected with human immune deficiency virus (HIV) or those with defective cell-mediated immunity. Since treatment of cryptococcal meningitis poses a big challenge, the present study aimed to develop a novel liposomal therapeutic formulation against cryptococcosis. Treatment with tuftsin-incorporated liposomes increased the anti-cryptococcal activity of murine peritoneal macrophages. Prophylactic treatment of mice with tuftsin-incorporated liposomes reduced the dissemination of C. neoformans to brain tissues. Moreover, the co-administration of tuftsin with nystatin liposomes augmented the anti-cryptococcal activity of nystatin, as mice treated with tuftsin-incorporated nystatin liposomes showed the highest survival and least fungal burden in their brain tissues. The results of the present study favour the use of immune-stimulating molecules along with antifungal agents in the treatment of opportunistic fungal infections.
