Immunological Activity of Vaccine Systems Containing Liposomal Nanocarriers against Protozoan-induced Diseases: A Systematic Review.

BACKGROUND

Neglected parasitic diseases constitute a broad spectrum of clinical conditions that, in the chronic phase, lack effective therapies for the target population. The utilization of vaccines based on liposomal nanocarrier systems is emerging, thereby enhancing clinical outcomes in various comorbidities. Consequently, this study aims to assess the immunological activity induced by liposomal nanocarriers against neglected parasitic diseases.

METHODS

For the review, the Pubmed, Embase, and Lilacs databases were used using the descriptors vaccine, parasite, and liposome. The following inclusion criteria were adopted: and experimental articles. As exclusion criteria: book chapters, editorials, literature reviews and duplicate articles found during the database search.

RESULTS

A total of 226 articles were identified, from which 34 were selected for review. The primary diseases identified included Babesia bovis, . An elevation in cytokines such as GM-CSF, MCP-1, IFN-γ, TNF-α, IL-2, IL-4, IL-5, IL-6, IL-10, IL-12, and IL-17 was observed in the studies evaluated regarding the parasitic diseases. Furthermore, cytokines such as IL-4, IL-10, and TGF-β were diminished with the administration of the vaccine systems in those studies.

CONCLUSION

Therefore, the administration of liposomal nanovaccine systems can effectively ameliorate the clinical condition of patients by modulating their immunological profile.
