Abstract

Trypanosoma cruzi, the etiological agent of Chagas Disease or American trypanosomiasis, is highly heterogenetic, with multiple genotypes and phenotypes currently recognized. At present, T. cruzi is classified into six Discrete Typing Units (DTUs), TcI-TcVI, infecting humans along with the TcVII, which infects bats. Each DTU/genetic subdivision has a distinct biological and host association, clinical outcomes, pathogenicity and genotype. This genotypic and phenotypic heterogeneity is associated to different clinical presentations of Chagas Disease, such as disease progression, drug susceptibility and transmission cycles. While it has been demonstrated that there is an association between T. cruzi morphology, virulence and pathogenicity, the glycoproteome-pathogenicity relationship has not been established. Glycoproteins play key roles in vector-parasite-host interaction during the intricate life cycle of T. cruzi. The rationale of the proposed study is based on findings from a recent glycoproteomic-centric study published by our group that showed the stage-specific modulation of T. cruzi glycoproteome. The present project offers a platform to explore in detail the fine structure and functions of the glycoproteome of different virulent and avirulent T. cruzi strains and correlate the glycoproteome to the clinical and biological characteristics of T. cruzi. The aims of this project are: 1) characterize the N- and O-glycoproteome of a range of T. cruzi strains with varying degrees of virulence and drug resistance. This objective will be achieved by exploiting state-of-the-art LC-MS/MS instrumentation established in Professor Palmisano's laboratory. This analysis will be complemented by a deep glycomics analysis that will be performed in the laboratory of Prof. Morten Thaysen-Andersen at Macquarie University, Sydney, Australia; 2) correlate the glycoproteome profiles/signatures and the pathogenicity and virulence of the different T. cruzi strains representative of the six T. cruzi DTUs and other closely related trypanosomatids. Glycoproteome analysis of the existing T. cruzi DTUs are missing, and it is unknown whether the glycosylation of the surface proteins have an impact on the pathogenicity of T. cruzi parasites; 3) expand the knowledgebase of T. cruzi glycoproteins, which form potential therapeutic targets against Chagas Disease. The mass spectrometry-based data will be complemented with lectin array and immunoblotting analyses that will shed new lights on the strain-specific variety of T. cruzi glycosylation. The knowledge gained from this mass spectrometry-based glycoproteomics study will elucidate the glycoproteome-pathogenicity relationship, which will have a profound impact on the current phylogenetic knowledge and expand our understanding of the importance of protein glycosylation in the pathogenicity of T. cruzi.
