Molecular and Immunological Properties of a Chimeric Glycosyl Hydrolase 18 Based on Immunoinformatics Approaches: A Design of a New Anti-Leishmania Vaccine

Leishmaniasis is a chronic inflammatory zoonotic illness caused by protozoan flagellates belonging to the Leishmania genus. Current data suggest that over 1 billion people worldwide are susceptible to infection, primarily in tropical and subtropical countries, where up to 2 million new cases are reported annually. Therefore, the development of a vaccine is crucial to combating this disease. This study employed immunoinformatics approaches to design a multiepitope anti-Leishmania vaccine, GH18-cpLeish, based on a cluster of six glycosyl hydrolases 18. We identified six helper T lymphocyte (HTL) epitopes and twenty-six cytotoxic T lymphocyte (CTL) epitopes with IC50 values
