The neuroimmunology biorepository was founded by Dr. Greenberg in 2009 and is maintained in collaboration with Dr. Nancy Monson. This effort utilizes an IRB approved protocol to seek permission from patients and controls for the acquisition of data and specimens that can be used in future research projects.
Specimens acquired include blood-based samples, cerebrospinal fluid-based samples, fecal material, urine and in some cases, tissue specimens. The repository processes via standardized protocols to collect serum, plasma, PBMCs, DNA, RNA, CSF supernatant and CSF cells. These samples are stored for future use and can be requested for collaborative projects by emailing Dr. Greenberg or Dr. Monson.
To date, over 7000 sample acquisitions have occurred. Samples from this resource have been used in numerous studies.
Dr. Greenberg’s research includes use of biospecimens to perform biomarker and antibody discovery work in collaboration with Dr. Nancy Monson and the pursuit of novel clinical trials. To date, the efforts surrounding biomarker studies have yielded insights into the immunologic effects of various medical therapies, the identification of novel autoantibodies and processes for analyzing T cell repertoires that could be useful for clinical medicine. Dr. Greenberg has served as PI for over 20 clinical trials including more than 5 phase 1 studies. He has been the IND holder for one trial and served on the international steering committee for multiple studies. Dr. Greenberg has worked to improve the efficiency and robustness for neuroimmunology clinical trials while also working to simplify the process for patients.
