Plasma-Derived Extracellular Vesicles as Potential Biomarkers in Heart Transplant Patient with Chronic Chagas Disease

Chagas disease is emerging in countries to which it is not endemic. Biomarkers for earlier therapeutic response assessment in patients with chronic Chagas disease are needed. We profiled plasma-derived extracellular vesicles from a heart transplant patient with chronic Chagas disease and showed the potential of this approach for discovering such biomarkers. Barcelona Institute for Global Health (ISGlobal) receives support from the Spanish Ministry of Science, Innovation and Universities through the Centro de Excelencia Severo Ochoa 2019–2023 Program (CEX2018-000806-S). ISGlobal and Institut d’Investigació en Ciències de la Salut Germans Trias i Pujol (IGTP) are members of the Centres de Recerca de Catalunya (CERCA Program), Generalitat de Catalunya. Work in the laboratory of C.F.B. is funded by Fundació La Marató de TV3 (reference 566/U/2018) and Fundación Mundo Sano. This project was co-financed by the European Union through the European Regional Development Fund with the support of Secretaria d’Universitats i Recerca del Departament d’Empresa i Coneixement de la Generalitat de Catalunya. N.C., M.G., J.G., and M.J.P. receive funds from the Redes temáticas de investigación cooperativa en salud (RETICS), Spanish Tropical Diseases Network “RD12/0018/0010” and from the Agencia de Gestió d’Ajuts Universitaris i de Recerca, Generalitat de Catalunya; grant “2017 SGR 00924.” M.G., C.B., J.G., M.J.P., and I.C.A. belong to the Ibero-American Nuevas Herramientas para el Diagnóstico y la Evaluación del Paciente con Enfermedad de Chagas network. I.C.A. is partially supported by grants no. 2G12MD007592 and 5U54MD007592 from the National Institute on Minority Health and Health Disparities of the US National Institutes of Health. We are grateful to the Biomolecule Analysis Core Facility at University of Texas at El Paso, Border Biomedical Research Center, funded by National Institute on Minority Health and Health Disparities grants 2G12MD007592 and 5U54MD007592. M.T.M. received a PhD fellowship from the Science Without Borders Program, Coordenação de Aperfeiçoamento de Pessoal de Nível Superior, Brazil. Sí
