Abstract :

Malaria is a disease which is spread around the globe. It causes hundreds of millions of clinical infections and at least a million deaths per annum. This disease is caused by the transmission of Plasmodium. The Plasmodium yoelii is a rodent malaria parasite. The malarial parasite maturation occurs within the erythrocyte. In final phase a large plasmodial protein which becomes a significant surface protein of merozoite (MSP119) is synthesized. Hence epitopes against MSP119 protein could be helpful in study to develop the vaccine against malaria. In the present work merozoite surface protein (msp119) of Plasmodium yoelii was selected as an immunogenic protein. The T-cell and B-cell epitopes for MSP119 were predicted using a range of computational tools/servers. The epitopes being expressed by the protozoa were identified. Subsequent to epitope (small peptides) prediction, the 3D structures of predicted epitopes were modeled by homology modeling followed by validation. Further the MHC molecules of human were identified and their structures were obtained from the Protein Data Bank. The predicted epitope were docked with their respective MHC alleles. The epitopes which were having lowest docking energy scores were selected as most promising epitopes for MSP119.Those predicted epitopes for MSP119 might act as potential vaccine candidates against the Plasmodium yoelii. In future those epitopes (small peptides) can be synthesized in wet laboratory and their immunogenic property can be validated.
