2006-2007 DRAK2: Target for New Therapy Martina Gatzka, M.D. University of California Irvine, CA Modulation of central and peripheral immunological tolerance by DRAK2, a negative regulator of lymphocyte signaling When T lymphocytes, a type of white blood cell, cannot distinguish between self and non-self tissues, they contribute to inflammation...

2006-2007 Arthritis and Growth in Children Hulya Bukulmez, M.D. Case Western Reserve University Cleveland, OH Does disruption of the C-type natriuretic peptide (CNP) signaling pathway cause cartilage degradation and growth retardation in juvenile rheumatoid arthritis? Dr. Bukulmez is studying the effect of chronic arthritis on a child’s growth. The...

2006-2007 Enzyme Predisposes to Autoimmune Disorders Nunzio Bottini, M.D. University of Southern California Los Angeles, CA PTPN22: Enzymology of an Autoimmune-Predisposing Tyrosine Phosphate Variant Bottini’s laboratory is studying an enzyme called lymphoid phosphatase, which acts as a critical gatekeeper of the activation of immune cells. Individuals carrying a particular...

2007-2008 Focusing on the Cause of OA Noboru Taniguchi, M.D., Ph.D. The Scripps Research Institute La Jolla, CA A novel chromatin protein involved in cartilage homeostasis and osteoarthritis Osteoarthritis is the most prevalent joint disease. It begins with disruption of the cartilage surface and leads to progressive cartilage damage....

2007-2008 Understanding the Defective Immune System Ziaur Rahman, M.D., Ph.D. Thomas Jefferson University Philadelphia, PA Impact of lupus susceptibility loci on peripheral B cell tolerance The human immune system is wonderfully efficient and complex. This system develops weapons, called antibodies, to use against viral and bacterial infections. When antibodies...

2007-2008 From Stem Cells to Cartilage Repair Audrey McAlinden, Ph.D. Washington University School of Medicine St. Louis, MO Induction of articular (hyaline) cartilage differentiation from human adipose-derived mesenchymal stromal cells Articular cartilage is an essential component of our joints, providing a lubricating, low-friction, gliding surface. This tissue contains no...

2007-2008 Growth Factors in Cartilage Cells: A Novel Therapy Chuanju Liu, Ph.D. New York University School of Medicine New York, NY GEP: A Novel Chondrogenic Growth Factor and Target in Arthritis The molecular mechanisms controlling cartilage formation, and specifically those relating to the osteoarthritis, are still unclear. It is...
