Awwal 30, 1432 H/March 5, 2011, SPA -- In collaboration with Laboratory of Human Genetics of Infectious Diseases at Paris Descartes University in France and Laboratory of Human Genetics of Infectious Diseases in Rockefeller University in the United States of America under the supervision of Professor John Laurent Casanova, researchers from Prince Naif Program for International Cooperation in Immunology Research at King Saud University (KSU) led by Dr. Saleh bin Zaid Al-Mohsen overseeing the program and the director of Prince Naif Center for Health Research have succeeded in discovering the most common cause of inflammatory innate in children, resulting from the disruption of the immune system in the composite named Interleukin 17 (IL-17). This study has been published by Science Magazine which is considered as the best scientific journals across the world. Dr. Saleh Al-Mohsen, head of research team from KSU has emphasized on the importance of this discovery and its results, since knowing the real cause of recurrent inflammatory innate will enable the development of new drugs to fight these infections and overcome them.
