Título: | Analysis of the Dynamics of Infiltrating CD4+ T Cell Subsets in the Heart during Experimental Trypanosoma cruzi Infection |
Autor: | Sanoja, Cristina; Carbajosa, Sofía CSIC; Fresno, Manuel CSIC ORCID ; Gironès, Núria CSIC ORCID | Fecha de publicación: | 11-jun-2013 | Editor: | Public Library of Science | Citación: | PLoS ONE 8 (2013) | Resumen: | Chagas disease, caused by the protozoan parasite Trypanosoma cruzi, affects several million people in Latin America. Myocarditis, observed during both the acute and chronic phases of the disease, is characterized by an inammatory mononuclear cell infiltrate that includes CD4+ T cells. It is known that Th1 cytokines help to control infection. The role that Treg and Th17 cells may play in disease outcome, however, has not been completely elucidated. We performed a comparative study of the dynamics of CD4+ T cell subsets after infection with the T. cruzi Y strain during both the acute and chronic phases of the disease using susceptible BALB/c and non-susceptible C57BL/6 mice infected with high or low parasite inocula. During the acute phase, infected C57BL/6 mice showed high levels of CD4+ T cell infiltration and expression of Th1 cytokines in the heart associated with the presence of Treg cells. In contrast, infected BALB/c mice had a high heart parasite burden, low heart CD4+ T cell infiltration and low levels of Th1 and inflammatory cytokines, but with an increased presence of Th17 cells. Moreover, an increase in the expression of IL-6 in susceptible mice was associated with lethality upon infection with a high parasite load. Chronically infected BALB/c mice continued to present higher parasite burdens than C57BL/6 mice and also higher levels of IFN-γ, TNF, IL-10 and TGF-β. Thus, the regulation of the Th1 response by Treg cells in the acute phase may play a protective role in non-susceptible mice irrespective of parasite numbers. On the other hand, Th17 cells may protect susceptible mice at low levels of infection, but could, in association with IL-6, be pathogenic at high parasite loads. © 2013 Sanoja et al. | URI: | http://hdl.handle.net/10261/159247 | DOI: | 10.1371/journal.pone.0065820 | Identificadores: | doi: 10.1371/journal.pone.0065820 issn: 1932-6203 |
