Abstract:
:Toxoplasma gondii is an obligate intracellular parasite that is globally distributed and can infect almost all warm-blooded animals, including humans. While vaccines are not available for prophylaxis, there are limited therapeutic options which often do not result in eradication of parasites from patients. ME49 is a cystogenic strain of T. gondii with a potential as a vaccine candidate. Excretory and secretory (ES) proteins are thought to play crucial roles in host-parasite interactions. Hence, we predicted and functionally annotated the ES proteins in T. gondii ME49 using public databases. ES proteins were further examined for the characteristics and possible functions through gene ontology (GO) term enrichment and analyses of metabolic pathways, enzyme code distribution (EC distributing) and protein domains. The potential antigenicity of T. gondii ME49 ES proteins was evaluated for the first time using Abundance of Antigenic Regions (AAR) value to predict the antigenic potential by measuring sequence length and number of antigenic regions. The results showed that the ES proteins have different AAR values at RNA and microarray level. Our studies provide valuable information for future experimental studies, including the identification of novel ES proteins of therapeutic, diagnostic and immunoprophylactic interests.
