Dr. Benjamin Greenberg joined Dr. GG deFiebre of SRNA on our podcast series, “Ask the Expert: Research Edition.” This episode is titled “Update: Study to Investigate the Safety of the Transplantation of Human Glial Restricted Progenitor Cells into Patients with Transverse Myelitis.” Dr. Greenberg discussed the background and status of the study. It is the first of its kind to look at the potential use of stem cells to repair the damage in spinal cords affected by myelitis, inflammation in the spinal cord. He also explained the screening process, enrollment, and next steps of the study.

The Community Meets Clinic podcast series introduces clinicians and healthcare personnel specializing in rare neuroimmune disorders. In this episode, Krissy Dilger of SRNA spoke with Dr. Ayşe Altıntaş, Professor of Neurology at Koç University School of Medicine in Istanbul, Turkey, which has been designated as a Center of Excellence in Rare Neuroimmune Disorders. Dr. Altıntaş described the unmet needs in rare neuroimmune disorders and noted her role on an international panel developing updated NMOSD diagnostic criteria [00:03:40]. She outlined current research on mechanisms of optic neuritis, pregnancy complications and aquaporin-4 antibodies, and developing accessible biomarkers beyond CSF with a future goal of remote monitoring [00:06:01]. Dr. Altıntaş also explained Koç University’s multidisciplinary demyelinating disease center model, emphasizing coordinated consultations, advanced MRI capabilities, shared decision-making, and the value of specialized centers, while expressing hope due to rapid advances in biomarkers and targeted therapies [00:11:43].

![504. Managing the Dread of Relapse
In this ABCs of NMOSD episode, Landy Thomas of SRNA was joined by Heather Dawn Sowalla. Heather shared her journey with neuromyelitis optica spectrum disorder (NMOSD) [00:01:54] and discussed the fear of relapse associated with the condition [00:14:04]. She described how long-term misdiagnosis and numerous flares impacted her life and mental health [00:16:02]. She shared coping strategies and emphasized the importance of a supportive community and the advancements in NMO treatment [00:25:49]. Finally, Heather encouraged those newly diagnosed to seek a doctor they connect with and lean on the community for support [00:34:12].
Heather Sowalla has lived most of her life in Pennsylvania. After earning her Bachelors degree in Environmental Science and her Masters degree in Environmental Studies, she returned home to her families dairy farm where she utilized her degree focusing on sustainable agriculture. Heather also spent two summer seasons working in Alaska with the Fish and Wildlife Department focusing on sustainable fisheries. Heather first became symptomatic for NMOSD around 2004 and has since lost a good deal of her vision, but she is doing well otherwise. Heather is newly engaged to Doug, a fellow NMOSD patient, and they plan on creating a life together in Vintondale, Pennsylvania.

![1311. Understanding Myelitis: Efforts to Update Diagnostic Criteria
In this episode of the SRNA Ask the Expert podcast moderated by Dr. GG deFiebre, Dr. Kyle Blackburn and Dr. Benjamin Greenberg discussed the need for updated diagnostic criteria for myelitis. Dr. Blackburn explained the term myelitis and the importance of precise terminologies for accurate diagnoses and research [00:05:10]. Dr. Greenberg elaborated on the advancements in testing and understanding of associated disorders like NMOSD and MOGAD since 2002 [00:11:10]. Both experts stated that the shift from transverse myelitis to myelitis will aid future research, treatments, and patient care [00:17:27]. They reassured patients that these changes would essentially refine their care but not alter it dramatically [00:23:40]. They encouraged patients to stay informed and communicate with their healthcare providers about these updates [00:28:58].
Kyle Blackburn, MD is an Assistant Professor in the Department of Neurology at UT Southwestern Medical Center in Dallas, Texas. He specializes in neuroimmunology and has clinical interests in antibody-mediated neurologic disorders, including autoimmune encephalitis, epilepsy, and ataxias; neurologic complications of cancers, including paraneoplastic disorders and checkpoint inhibitor/CAR T-cell toxicity; and demyelinating disorders, including sarcoidosis, neuromyelitis optica, myelin oligodendrocyte glycoprotein (MOG)-associated disease, and multiple sclerosis.
Dr. Blackburn earned his medical degree at the University of Kentucky College of Medicine. He performed his residency in adult neurology at UT Southwestern, serving his final year as Chief Resident, and stayed to complete a fellowship in neuroimmunology, during which he earned the James T. Lubin Clinician Scientist Award from the Siegel Rare Neuroimmune Association (SRNA). He joined the UT Southwestern faculty in 2020.

He is also the interim Director of the Multiple Sclerosis Center and the Director of the Neurosciences Clinical Research Center. In addition, he serves as Director of the Transverse Myelitis and Neuromyelitis Optica Program and the Pediatric Demyelinating Disease Program at Children’s Medical Center.
Dr. Greenberg earned his medical degree at Baylor College of Medicine before completing an internal medicine internship at Chicago’s Rush Presbyterian-St. Luke’s Medical Center. He performed his neurology residency at the Johns Hopkins School of Medicine. He also holds an M.H.S. in molecular microbiology and immunology from the Bloomberg School of Public Health, as well as a bachelor’s degree in the history of medicine – both from Johns Hopkins. Prior to his recruitment to UT Southwestern in 2009, Dr. Greenberg was on the faculty of the Johns Hopkins Division of Neuroimmunology, serving as the Director of the Encephalitis Center and Co-Director of the nation’s first dedicated Transverse Myelitis Center.
