Research, Service, and Training Interests

Dr. Iritani joined the Faculty in Comparative Medicine in 1999.  His major clinical interests include small animal medicine and surgery.  He is currently a Senior Clinical Veterinarian, Director of Surgery, Co-Director of Training Programs, Director of Clerkship Training for Veterinary Students.  He is a member of the Fred Hutchinson Cancer Research Center Consortium, Nutrition and Obesity Research Center (NORC), Diabetes and Endocrine Research Center (DERC), Solid tumor and translational research team (STTR), Molecular and Cellular Biology  (MCB) Graduate Program, Initiative for Maximizing Student Diversity (IMSD).  Dr. Iritani serves on numerous NIH Study Sections in Basic Immunology and is on the Editorial Review Boards for Comparative Medicine and JAALAS.

The Iritani lab studies the normal functions of oncoproteins and other signaling molecules in the development and function of immune cells, and how when dysregulated, aberrant expression or activity can result in immunodeficiency diseases or cancer.  Among the oncoproteins the Iritani lab studies include the Ras GTPases, Raf kinase, and the Myc family of transcriptional regulators. More recently the Iritani lab has become interested in the metabolic control of lymphocyte development by the Folliculin Interacting Proteins (Fnip1 and Fnip2), and the regulation of immune cell functions by Hematopoietic Protein-1 (Hem1) and the actin cytoskeleton.
