Chagas disease is caused by infection with the protozoan Trypanosoma cruzi and affects over 8 million people worldwide. In spite of a powerful innate adaptive immune response in acute infection, parasite evades eradication, leading to chronic persistent low parasitism. Chronically infected subjects display differential patterns progression. While 30% develop cardiomyopathy (CCC) – severe inflammatory dilated decades after 60% patients remain disease-free, asymptomatic/indeterminate (ASY)...

ABSTRACT Background Clinical recurrence of COVID-19 in convalescent patients has been reported, which immune mechanisms have not thoroughly investigated. Presence neutralizing antibodies suggests other types response are involved. Methods We assessed the innate type I/III IFN response, T cell responses to SARS-CoV-2 with IFNγ ELISPOT, binding and antibody assays, two monozygotic twin pairs one case. Results In pair 1, four months after a first mild episode infection for both siblings,...

Fibrosarcomas are soft tissue mesenchymal tumors originating from transformed fibroblasts. Fibroblast growth factor-2 (FGF2) and its tyrosine-kinase receptors (FGFRs) play pivotal roles in fibrosarcoma onset progression, FGF2 being actively produced by fibroblasts all stages along their malignant transformation to the stage. The soluble pattern recognition receptor long pentraxin-3 (PTX3) is an extrinsic oncosuppressor whose expression reduced different tumor types, including sarcomas, via...

Chagas disease, caused by the protozoan Trypanosoma cruzi, is an endemic parasitic disease of Latin America, affecting 7 million people. Although most patients are asymptomatic, 30% develop complications, including often-fatal Chronic Chagasic Cardiomyopathy (CCC). previous studies have demonstrated some genetic deregulations associated with CCCs, causes their remain poorly described. Based on bulk RNA-seq and whole genome DNA methylation data, we investigated epigenetic present in moderate...

Recurrence of COVID-19 in recovered patients has been increasingly reported. However, the immune mechanisms behind recurrence have not thoroughly investigated. The presence neutralizing antibodies (nAbs) recurrence/reinfection cases suggests that other types response are involved protection against recurrence.

Chagas disease is a parasitic from South America, affecting around 7 million people worldwide. Decades after the infection, 30% of develop chronic forms, including Chronic Cardiomyopathy (CCC), for which no treatment exists. Two stages characterized this form: moderate form, by heart ejection fraction (EF) ≥ 0.4, and severe associated to an EF < 0.4. We propose two sets DNA methylation biomarkers can predict in blood CCC occurrence, stage. This analysis, based on machine learning algorithms,...

Cardiomyopathies are major causes of heart failure. Chagas disease (CD) is caused by the parasite Trypanosoma cruzi, and it endemic in Central, South America. Thirty percent cases evolve into chronic cardiomyopathy (CCC) with worse prognosis as compared other cardiomyopathies.
