Prior to joining North Shore-LIJ Health System, Dr. Bloom performed her postdoctoral studies and served as an associate research scientist in the Departments of Cell Biology and Immunology at the Yale University School of Medicine. Her studies at Yale focused on understanding how immune cells communicate with each other. Dr. Bloom received her PhD from The Rockefeller University in 2002, where she studied molecular and cellular neuroscience in the laboratory of Professor Paul Greengard. Her PhD studies were focused on understanding the molecular anatomy of synapses, the points of communication between nerve cells.
A major interest of Dr. Bloom’s lab is to understand how to limit damage and provide a pro-regenerative environment to nerve cells after spinal cord injury (SCI), which affects more than 10,000 people per year in the United States. The acute response to SCI includes diverse processes that both limit (e.g. inflammation), and promote (e.g. growth factors) recovery. To identify molecular programs that accompany successful and unsuccessful regeneration after nerve cell injury, Dr. Bloom’s research group is using biochemical, cell biological and functional genomics methods. In addition to unbiased approaches, they are also specifically investigating the inflammatory response after SCI, in both clinical and pre-clinical studies, with the hopes of identifying new targets for potential therapeutic intervention.
Dr. Bloom’s clinical studies on spinal cord injury are performed in collaboration with Dr. Stein, Chairman, Department of Physical Medicine and Rehabilitation of the North Shore-LIJ Health System and Dr. Bank, Director, Section of Trauma, Department of Surgery, of North Shore University Hospital. Dr. Bloom also collaborates with Feinstein colleague Dr. Nadeen Chahine to understand the role of inflammation in degenerative disc disease.
Another focus of Dr. Bloom’s lab, pursued together with Feinstein colleagues Dr. Betty Diamond and Dr. Yousef Al-Abed, is to develop novel therapeutic agents for the treatment of lupus. Lupus is a chronic autoimmune disease that affects approximately 1.5 million Americans. The disease is characterized by the presence of antibodies against the patient, which can lead to damage and symptoms in multiple organs, including the nervous system. Dr. Bloom’s lab is performing pre-clinical studies, based on discoveries from Dr. Diamond’s lab, to neutralize autoantibodies that damage nerve cells, and other cell types.
