Abstract :

Tuberculosis (TB) is a major infectious disease of global importance and the World Health has declared TB a ?global emergency?. The comparative analyses of Mycobacterium tuberculosis genome with the genome of other mycobacteria have identified several regions of differences (RDs), which are specific for M. tuberculosis. Hence, the proteins and peptides encoded by the genes present in these RDs may be useful in the diagnosis of TB and the development of new vaccines. In this study RD genes, proteins and peptides were characterized using the methods of OMICS, to identify the proteins and peptides of diagnostic and vaccine potential. The testing of RD proteins and peptides sera of TB patients and healthy subjects identified two proteins and three peptides of diagnostic relevance. The bioinformatics analysis showed each peptide had several antibody-binding epitopes. In cellular immune responses, five proteins were recognized as the major antigens. The bioinformatics analysis for binding to HLA-DR molecules showed that all of these proteins were promiscuous HLA binders. However, an immunodominant peptide of PPE68 was recognized equally well by TB patients as well as healthy subjects. The bioinformatics analysis of the peptide sequence for identity in the bacterial data base and HLA-DR binding showed that the immunodominant peptide was shared between various mycobacterial species and was highly promiscuous for binding to HLA molecules. In conclusion, the OMICS analyses has identified immunodominant RD proteins and peptides useful for TB diagnosis and vaccine applications. The study was supported by Kuwait University Research Sector grants MI02/12 and GM01/01.
