The Institute of Cell Biology and Immunology Thurgau (BITG) is an academic research institution located in Kreuzlingen, Switzerland. The institute focuses on application-oriented basic research in the field of tumor biology, immunology and cell biology.

The Foundation for Science and Research of the Canton Thurgau (Thurgauische Stiftung für Wissenschaft und Forschung, TSWF), founded BITG in 1999 in close collaboration with the University of Konstanz. The Thurgovian Foundation still supports the institute financially. Academically, BITG is associated with the University of Konstanz and affiliated with the Department of Biology. The Institute also participates in the university's lecturing and academic training programmes. Since 2004 BITG is recognized as a Swiss research institution of national relevance and it is supported by the Federal Department of Economic Affairs, Education and Research of the State Secretariat for Education, Research and Innovation.

Many research projects at BITG are financed by means of third-party grants, such as the Swiss National Science Foundation, the Thurgovian Cancer League and other foundations.

Our research activities are assessed by a distinguished advisory board. The high quality of our research is thus guaranteed. The results of our research are continuously published in international journals and therefore made publically available.
