The Max Planck Institute of Immunobiology and Epigenetics (MPI) in Freiburg, Germany, is an interdisciplinary research institute that conducts basic research in modern immunobiology and developmental biology. It was founded in 1961 as Max Planck Institute of Immunobiology and is one of 80 institutions of the Max Planck Society.
The researchers of the MPI study the development of the immune system and analyse the genes and molecules which are important for its function. They also seek to establish which factors control the maturation of immune cells and how chemical changes of the DNA influence the immune defense.
In 2007, the Max Planck Institute of Immunobiology added Epigenetics as a new research area. In 2010, the institute changed its name to Max Planck Institute of Immunobiology and Epigenetics. The 1984 Nobel Prize-winning biologist Georges J. F. Köhler was a director of the institute from 1984 until his death in 1995.
