Dissecting the association of anti-microbiota antibodies and auto-reactive T-cells in cardiomyopathy– an exploratory research Project

Micha T. Maeder, Susanne Vetsch & Burkhard Ludewig

Kurzfassung Prospective research project in which biological material is sampled from humans and health-related personal data is collected (HFV Art 6).
To generate further scientific evidence for a potential role of crossreactive antimicrobial T and B cell responses in patients with heart failure.
i) Determine the levels of anti-heart proteins - and anti-microbiota specific antibodies in serum of patients with newly diagnosed heart failure of non-ischemic origin, patients with active or recent myocarditits/perimyocarditis and controls.
ii) Determine the abundance of heart-reactive and crossreactive antimicrobial effector T cells in PBMCs from patients with heart failure, myocarditis/perimyocarditis and controls.
iii) Determine if the HLA-DQB1*03:01 molecule is linked to the development of cardiac autoimmunity and heart failure
