Abstract
Extracellular Vesicles (EVs) have evolved as a promising entity for developing diagnostic and therapeutic biomarkers. We profiled global EV proteome of EVs from Human retinal cells (ARPE-19) infected with S. aureus and P. aeruginosa. EVs were isolated by ultracentrifugation and subjected to LC-MS/MS for proteome analysis. In S. aureus infection, sequest identified 864 proteins, of which 81 were differentially expressed in comparison to control. Similarly, in P. aeruginosa infection, of 516 proteins identified, 86 were differentially expressed. Additionally, 38 proteins were exclusive to infected sets. KEGG and Gene Ontology revealed crucial dysregulated pathways involving proteins such as complement cascades, annexins and calpain-2, all playing major role in the pathogenesis of the disease. This study provides insight into the global EV proteome of S. aureus and P. aeruginosa endophthalmitis with their functional correlation and distinctive pattern of expression. Calpain-2 and C8a are attractive biomarkers for bacterial endophthalmitis.
