Irun R. Cohen (born September 1, 1937 in Chicago ) is an Israeli-American medic and immunologist .

Life

Cohen first studied philosophy at Northwestern University (Bachelor of the College of Liberal Arts 1959) and then medicine at Northwestern Medical School (MD 1963). He completed his specialist training in pediatrics in Jerusalem (internship from 1963 to 1964 at Hadassah University Hospital) and at Johns Hopkins University Hospital (residency from 1966 to 1968). In between he was a seconded officer from 1964 to 1966 with the US Public Health Service at the Center for Disease Control in Atlanta , where he researched infectious diseases. After completing his specialist training, he was at the Weizmann Institute from 1968 to 1971 with a grant from the Arthritis Foundation . He stayed at the Weizmann Institute, where he became Associate Professor in 1974 and Professor of Immunology in 1987 (most recently Mauersberger Professor ) and from 2007 Professor Emeritus. From 1993 to 2001 he was director of the Robert Koch-Minerva Center for research in autoimmune diseases . From 1997 to 2001 he was director of the Center for the Study of Emerging Diseases in Jerusalem and from 2004 to 2006 director of the National Center for Biotechnology in the Negev at Ben-Gurion University.

In 1989 he received the Robert Koch Prize .

He developed cloned T cells as functional tests for autoimmune diseases and an antigen microarray chip for tests of the immune system, which is inspired by his idea of ​​the immune system's self-image, which he calls the immunological homunculus . He developed this theory in 1989 as an alternative to the clone selection theory , based on his knowledge, for example gained from studying autoimmune diseases , that mechanisms for recognizing one's own antigens are present in the immune system and are similar to those with which foreign antigens are recognized. The immune system therefore has a picture of its own body and not just a picture of the exogenous world, but it reacts differently to the body's own cells.

He developed a T- cell vaccination against autoimmune diseases (such as rheumatoid arthritis , lupus erythematosus , multiple sclerosis ), which is in clinical trials. Instead of inactivated antigens against foreign substances, as in the usual vaccination, inactivated own T cells are injected, which attack the own body in autoimmune diseases. He is director of the European Collaboration of T Cell Vaccination and director of the Israeli National Institute for T Cell Vaccination.

Cohen is also testing a vaccination with peptides for diabetes 1 based on parts of the heat shock protein Hsp60 after showing that this stops the self-destruction of beta cells in the islets of Langerhans . Cohen also sees this as a test of his homunculus theory, since the vaccination is based on modified endogenous substances.

He studies and works closely with scientists in the field of complex systems and is on the council of the Israeli National Center for Complex Systems. In particular, he deals with complex systems in biology and their simulation. He is co-inventor of an interactive visual language for the simulation of complex dynamic systems (reactive animation).

He also deals with the relationship between the Talmud and science.
