Robert Lafyatis  Photo Robert Lafyatis is Professor of Medicine and the Thomas Medsger Professor in Arthritis Research at the University of Pittsburgh School Of Medicine. He relocated from Boston University and joined our Division of Rheumatology and Clinical Immunology in September 2015, as Director of the UPMC and University of Pittsburgh Scleroderma Center. He sees patients in our Scleroderma Clinic. Dr. Lafyatis is a clinical rheumatologist and translational physician-scientist, investigating scleroderma pathogenesis and biomarkers of disease. He is a leader nationally and internationally in research into systemic sclerosis. His work includes molecular studies into the cause of fibrosis, inflammation and autoimmunity. He also studies new medications and has been the lead investigator on several clinical trials of novel medications for patients with systemic sclerosis. He has pioneered the use of biomarkers as outcome measures in patients with systemic sclerosis, and shown that these can be used successfully to assess patient responses to medications. Most recently he has shown that blocking one of the main mediators of fibrosis, TGF-beta, leads to dramatic improvement in biomarkers and clinical disease. Dr. Lafyatis has authored over 120 peer-reviewed articles and a number of book chapters on scleroderma pathogenesis. He has published review articles on topics ranging from SSc therapeutics and pathogenesis, mouse scleroderma models, to autoimmunity and innate immunity. Dr. Lafyatis chairs review panels for several NIH grant study sections responsible for reviewing research grant proposals. He is also a reviewer of manuscripts submitted to Journals, including, Arthritis and Rheumatism, Journal of Experimental Medicine and Journal of Investigative Dermatology. He co-chairs the International Workshop on Scleroderma Research, which has been held in the UK or Boston USA alternating for over 20 years. He is a Member of the Planning and Scientific Committees for the Systemic Sclerosis World Congress. He has co-chaired multiple sessions on scleroderma pathogenesis at American College of Rheumatology National Meetings. The unifying goal in his work is to find better treatments for patients with systemic sclerosis.

Thomas A. Medsger, Jr., MD
Thomas A. Medsger Photo Dr. Medsger received his medical degree at the University of Pennsylvania. He completed his internship at Jackson Memorial Hospital, and his rheumatology fellowship at the University of Pittsburgh. He is board certified in Internal Medicine and Rheumatology.

Dr. Medsger's research focuses on the epidemiology, clinical and laboratory features and natural history of systemic sclerosis (SSc) and localized forms of scleroderma (LScl), Raynaud disease and polymyositis/dermatomyositis. He and collaborators have described many serologic subsets of SSc and LScl, their distinctive clinical findings, survival and immunogenetic associations. He has developed a SSc disease severity index and has proposed criteria for the classification of early SSc. Current studies include cytokines and other soluble protein markers as SSc disease activity measures, lung transplantation, SSc in twins, and childhood onset SSc and LScl.

Patrizia Fuschiotti, PhD
Patrizia Fuschiotti Photo Patrizia Fuschiotti, Ph.D., received her degree in pharmaceutical chemistry and her Ph.D. in the immunopharmacology of tumors at the State University of Perugia, Italy. She completed her postdoctoral training at the National Institutes of Health in the Laboratory of Immunology (NIAID) in Bethesda, Maryland, studying the immunogenetics of immunoglobulins. Subsequently, she joined the Laboratoire d'Immunochimie - Centre National de la Recherche Scientifique (National Center for Scientific Research) in Grenoble, France, where she studied the T cells in newborns and adults. She then returned to the US, joining the Department of Immunology at the University of Pittsburgh in 2006 where she is currently an Assistant Professor of Immunology.

Dr. Fuschiotti's research focuses on how T cells and their products contribute to fibrosis in systemic sclerosis (SSc). She joined forces with Dr. Medsger and the staff of the Scleroderma Center. Her research has shown that a certain type of T cells (CD8 positive cells) produce a substance (interleukin 13 or IL-13) which participates in fibrosis. In recognition of her work, Dr. Fuschiotti has received a Marta Marx Research Award from the national Scleroderma Foundation. She is currently studying how CD8 positive T cells and IL-13 are regulated at the molecular level in the blood and skin of SSc patients. Blocking the effects of IL-13 may be a treatment strategy to prevent fibrosis in SSc and other diseases characterized by fibrosis.
