Prof Rinaldi is a clinician scientist and clinical neurologist who leads the University of Oxford’s programme of inflammatory neuropathy research. This research spans from in vitro disease modelling using cell-based assays to biomarker discovery, clinical phenotyping, and clinical trials. His lab have developed models of immune mediated axonal injury and demyelination using human induced pluripotent stem cell derived myelinating co-cultures. These experimental systems are now being used to learn more about the mechanisms of immune-mediated peripheral nerve injury, and are a valuable tool in the search for novel auto-antibodies and for the discovery and pre-clinical evaluation of fluid biomarkers. The lab also runs the only UK based diagnostic testing service for nodal and paranodal antibodies, which associate with distinct forms of autoimmune nodopathy, and the underlying B-cell biology of these and related peripheral nerve disorders is a more recent area of study. His research programme also includes a clinical / observational study of chronic inflammatory neuropathy (Bio-SPiN). The group additionally contributes to and benefits from close links with the comprehensive and high-quality clinical-serological database of 2000 patients encapsulated in the International GBS Outcome Study (IGOS), and has been involved in therapeutic trials in Guillain-Barré syndrome (GBS), chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), and multifocal motor neuropathy (MMN).

Clinical Associate Professor of Neurology, University of Arizona College of Medicine.

Dr. Saperstein has spent the last 20 years actively involved in research and patient care involving GBS and CIDP. He is currently in practice at Honor Health Neurology in Phoenix, AZ, where he is co-director of the GBS|CIDP Foundation Center of Excellence as well as a Clinical Associate Professor of Neurology at the University of Arizona College of Medicine.

Dr. Saperstein is a graduate of Boston University School of Medicine. He performed a Neurology residency at Wilford Hall USAF Medical Center in San Antonio, Texas, followed by a Neuromuscular Disease/Clinical Neurophysiology fellowship at the University of Texas Southwestern Medical Center in Dallas. Dr. Saperstein is board certified in Neurology, Neuromuscular Medicine, and Electrodiagnostic Medicine.

In addition to caring for patients with GBS and CIDP, he sees patients with other disorders of the nerves and muscle. Dr. Saperstein is active in multicentre research studies of treatments for neuropathies, amyotrophic lateral sclerosis, myasthenia gravis, and myositis. He often lectures to physicians and patients throughout the U.S. and has authored or co-authored over 50 journal articles, book chapters, and abstracts regarding various aspects of nerve and muscle disease.

Professor and the Associate Chair for Faculty Affairs of the Department of Neurology at the University of Chicago.

Betty Soliven, MD is a Professor and the Associate Chair for Faculty Affairs of the Department of Neurology at the University of Chicago. She is one of the leading experts in neuromuscular diseases such as Guillain Barré syndrome, chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), other inflammatory neuropathies, myasthenia gravis (MG) and myositis.  She is the Director of the Electrodiagnostic Laboratory and EMG/Neuromuscular training program at the University of Chicago. Under her leadership, the University of Chicago has been designated as one of the Centers of Excellence by GBS/CIDP International.

Dr. Soliven has a broad background in neuroscience research, including ion channels, glial biology and animal models of neurologic diseases. Her clinical and research interests have led to interesting publications on glial cell biology as well as pathogenetic and immunoregulatory mechanisms in a spontaneous autoimmune polyneuropathy in B7-2 deficient NOD mouse model and experimental autoimmune myasthenia gravis (EAMG). She and other investigators found that myelin P0 is the antigenic target in B7-2 deficient NOD mouse model where deletion of a co-stimulatory molecule leads to a switch of phenotype from type 1 diabetes to an inflammatory neuropathy mimicking CIDP.  In both animal models of autoimmune disease affecting the peripheral nerves or the neuromuscular junction, regulatory T cells and regulatory B cells play an important role in suppressing or modulating the disease severity. Her current research focuses on the potential roles of bile acid receptors in autoimmune neuropathy and myasthenia.

Her research has been funded by National Institute of Health, National Multiple Sclerosis Society, GBS/CIDP International and Conquer MG (previously known as MG Foundation of Illinois). She has also served as a manuscript reviewer for multiple journals as well as a grant reviewer for NIH study sections, GBS/CIDP International and other funding agencies. She is the Chair of the Medical Advisory Board for Conquer MG and a member of GBS/CIDP Foundation Global Advisory Board. She is also a member of American Academy of Neurology, American Neurological Association, American Association of Electrodiagnostic Medicine, Peripheral Nerve Society and Society for Neuroscience.
