Antiparasitic and immunomodulatory potential of oral nanocapsules encapsulated lactoferrin protein against plasmodium berghei

AIM: To analyze the effect of native buffalo lactoferrin (buLf) protein along with its nanoformulation using alginate-enclosed, chitosan-conjugated, calcium phosphate buffalo Lf nanocapsules (AEC-CCo-CP-buLf NCs) against rodent parasite Plasmodium berghei. MATERIALS & METHODS: BALB/c mice were infected with malaria parasite and efficacy of the proteins (buLf and NCs) was evaluated by measuring parasitemia, initialization, role of miRNA in absorption of NCs, parasite load by histopathology and quantitative determination, cytokine levels, bioavailability and immunohistochemistry to localize Lf protein. RESULTS: NCs significantly reduced the parasite load in mice compared with buLf and untreated group. NCs were found to be modulating the disease profile of mice as shown by immunohistochemistry, free radical ion production and higher survival tendency. CONCLUSION: Our study confirms that NCs internalized and changed the expression of miRNAs that further enhanced their uptake in various organs leading to inhibitory effect against the parasite as well as maintenance of the Fe metabolism.
