About EATRIS

The European Infrastructure for Translational Medicine (EATRIS) is a pan-European research infrastructure operating as a European Research Infrastructure Consortium (ERIC). It brings together cutting-edge facilities, research expertise, and technology platforms dedicated to accelerating the translation of scientific discoveries into new diagnostics, therapeutics, vaccines, and other medical interventions. By supporting all stages of the translational process, from target discovery and biomarker development to preclinical validation and early clinical application, EATRIS helps reduce development risks, shorten innovation timelines, and enhance the reproducibility and quality of translational research.

In the Czech Republic, the national network EATRIS-CZ integrates ten major research institutions and universities into this European framework. Each participating institution contributes complementary technological capacities and scientific expertise, enabling Czech research teams and industrial partners to benefit from coordinated access to sophisticated methodologies, shared infrastructure, and international collaboration opportunities. The Institute of Microbiology of the Czech Academy of Sciences (IMIC) is one of these partner institutions, contributing its specialized research environment to the national node.

By being part of EATRIS-CZ and the wider European EATRIS community, Czech academic and industrial users gain entry into a structured ecosystem that promotes cooperation across disciplines, facilitates knowledge exchange, and strengthens Europe’s collective capacity to translate biomedical discoveries into tangible societal benefits. This integration ensures that Czech research is embedded in a high-quality, internationally interconnected infrastructure dedicated to advancing translational medicine.
