Scientific Advisory Board Meeting August 5th, 2020
Dan Lewis Foundation

11:00-1:30 EST

Present:  David  Margulies (Moderator),  Hal  Lewis,  David  Meaney,  Mark  Bear,  Sudhir  Agrawal,  Stephen  Strittmatter,  Alan  Kopin,  Graham  Dempsey,  Kevin  Eggan,  Michael  Crair


--David Margulies opened the meeting with orienting remarks that provided a framework for the purpose and process of the meeting


--Several participants commented on the process of developing a foundation (for instance, FRAXA). There was discussion of how


successful foundations identify a niche and promote growth/momentum in various ways—fund postdocs to inject energy into an evolving research field, fund specifically targeted research, do advocacy work, link with other organizations/associations/foundations/government agencies.  Some participants offered the view that a hybrid model for growth of the Dan Lewis Foundation might be optimal.


--There was discussion about how best to categorize brain injury for purposes of intervention/outcome research. Acute vs. Chronic phase?  Severity of injury?   Pathophysiology of the injury? Targeted functions? Targeted neurological/neuropsychological deficits?


--There was general consensus that there is an abundance of research regarding medical approaches to limiting damage and preserving as much CNS integrity as possible during the acute phase following TBI. Conversely, there is a relative lack of research into medical approaches to regenerate CNS or to promote recovery of functioning during the chronic phase, especially in adults. Stephen Strittmatter noted that adults in the chronic phase of TBI recovery tend to have rather stable functional profiles while making slow, small functional gains. This may be seen as an advantage for doing small N outcome studies with chronic TBI subjects because even small accelerations in recovery of skills may be quite notable and significant. Hal Lewis agreed with this perspective based on observations of Dan’s consistent but painstakingly slow recovery.


--There was discussion of government agencies to which funding applications might be submitted. In particular, the general view was that both NIH and DOD  have not recently prioritized medical approaches to brain regeneration in adults in chronic phase of TBI. The group generally felt that this can be viewed as encouraging rather than discouraging as opportunities are present.


--There was discussion about whether there are any pharmaceutical companies that are investing in TBI products. Stephen Strittmatter said that pharma has generally been disappointed by attempts to research/manufacture meds for post-stroke patients which may have led to reluctance to pursue drugs for TBI. Participants were not aware of any pharm companies that are invested in TBI.


--Sudhir Agrawal brought up the need for a better understanding of the natural history/course of moderate/severe brain injury. He and others spoke of the potential value of a repository of the biomarkers of TBI over time.


--There was extensive discussion of cortical blindness (or what might better be called “cerebral visual impairment) as a possible starting target for the Foundation. Positives factors for choosing this target include: existing animal research, pharmacological intervention studies with animals have been done in regards to amblyopia and cortical blindness, outcome studies could likely be fairly easy to design, positive results (if obtained) could likely provide a template that could be transferred to other CNS circuits/functions. There was a consensus forming that this could be a good area to get started.


--There is some existing evidence that down regulation of Lynx1 gene can lead to modulation of inhibition of plasticity in the visual cortex thus leading to improvement in cerebral visual impairment.


--Michael Crair took a few minutes to introduce himself as he is new to Scientific Advisory Board.


--Hal Lewis announced that the Board of Directors, which has not yet met formally, will be meeting in 6-8 weeks with following topics for discussion:

1) Presentation of the Foundation’s proposed by-laws followed by discussion and vote on ratification of by-laws

2) Ways of funding the foundation’s research agenda

3) Connecting with other foundations, advocacy organizations

4) Ensuring good communication between the Board of Directors and the Scientific Advisory Board


--David Margulies took a few minutes to summarize today’s discussion, to initiate discussion of next steps, and to propose that he will distill today’s discussion into a document that provides greater specificity to the Foundation’s initial research agenda. This document will be distributed to the Scientific Advisory Board in draft form around the beginning of September and comments, edits, suggested inclusions/exclusions will be solicited. Hopefully, when the plan is consolidated it will, via the Foundation website and also a PowerPoint presentation, provide a platform for various types of fund raising. David also encouraged all participants to forward questions/comments/suggestions etc. at any time, including before the draft research agenda is distributed.

For the third consecutive year, the Dan Lewis Foundation for Brain Regeneration is proud to announce the DLF Prize competition. The 2025 DLF Prize, a $20,000 award, will recognize an outstanding early career scientist (2 to 5 years post-doc) conducting innovative research in neuroscience, pharmacology, or biotechnology. This prestigious prize honors researchers whose work aligns with the DLF mission to drive breakthroughs in neural regeneration and repair. The current research priorities of the DLF are: Pharmacological Reactivation of Neural Repair: Research into pharmacological methods of reactivating or augmenting synaptogenesis, neurogenesis or axonal repair. Cell-Based Cortical Repair: Investigating the potential of derived cortical neurons to restore function in damaged cortical regions. Transcriptomics of Neural Recovery: Characterizing transcriptomic profiles of cortical neurons in the recovery phase following brain injury to identify pathways that drive repair. Molecular Inhibitor Targeting: Advancing anti-sense oligonucleotides (ASO’s) or small-molecule therapeutics designed to downregulate inhibitors of neural regeneration in the cortex or spinal cord. Application for the 2025 DLF Prize can be made by going to our website— danlewisfoundation.org —and clicking on the Tab “ 2025 DLF Prize ”. This will bring you into the application portal. The application portal opened in March, 2025 and will remain open through May 31st. Once in the portal, you will find complete information about the DLF prize, eligibility requirements, and an application form which can be filled in and submitted online. The winner of the 2023 DLF Prize, Dr. Roy Maimon, continues his research indicating that downregulation of PTBP1, an RNA-binding protein, can convert glial cells into neurons in the adult brain (Maimon et al. 2024) .* Dr. Maimon, currently a post-doc at the University of California, San Diego is currently interviewing for a faculty position at several prominent neuroscience departments. The winner of the 2024 DLF Prize, Dr. William Zeiger is a physician-scientist in the Department of Neurology, Movement Disorders Division, at UCLA. Dr. Zeiger has expertise in interrogating neural circuits using a classic “lesional neurology” approach. He states, “Our lab remains focused on understanding how neural circuits become dysfunctional after lesions to the cortex and on investigating novel circuit-based approaches to reactivate and restore damaged cortex”. * Maimon, Roy, Carlos Chillon-Marinas, Sonia Vazquez-Sanchez, Colin Kern, Kresna Jenie, Kseniya Malukhina, Stephen Moore, et al. 2024. “Re-Activation of Neurogenic Niches in Aging Brain.” BioRxiv. https://doi.org/10.1101/2024.01.27.575940.

Alan was injured in 2021, at age 42. An art teacher in Lakewood, Colorado, Alan was riding his bicycle after school and was crossing at an intersection when a truck turned into the crosswalk area and hit him. Alan reports no memory of the event but has been told this is what happened. Alan says “My frontal lobe took the brunt of the impact, particularly the left frontal lobe”. Alan had a 2 ½ week stay at a nearby hospital where he, “re-learned to talk, to walk, and drink”-- although again he reports no memory of his stay there. Alan was then transferred to Craig Rehabilitation Hospital, in Englewood, Colorado. Alan says, “The only reason I knew I was at Craig is that I rolled over in bed and saw “Welcome to Craig” on the dry erase board.” During this stage of recovering, Alan repeatedly denied that he had been in an accident. Twice he tried to leave Craig on his own accord despite his wife’s and his therapists’ assurances that it was important for him to stay to recuperate from his injuries. Alan’s wife was 8 months pregnant at the time of his accident and gave birth to their son while Alan was an inpatient at Craig. Alan’s wife brought his newborn son to visit him days after the birth and Alan held him while sitting in his wheelchair, but Alan wistfully reports this is another thing he can’t remember. Alan reports that he still has significant difficulties with memory. Alan has also experienced several other neuropsychological difficulties. He states that for months after his injury, he could not experience emotion. “I could not laugh, I couldn’t cry.” Even after three years, his emotional experience is constricted. However, an emotion that is sometimes elevated is irritation and anger. Sometimes, dealing with people can be difficult because he may have temper flare-ups with little reason. This is something that Alan regrets and he is working hard with his neuropsychologist to improve the regulation of his emotions. Alan also has difficulty with organization, motivation, and distractibility. Earlier in his recovery, he had trouble sequencing and had difficulty carrying out personal and household routines. Alan has benefited greatly from therapy and his own hard work to make improvements in these areas. A chief reason that Alan works so hard in his recovery is so that he can be a good father to his son who is now almost 3 years old. He recognizes that it is important not to get frustrated when it seems that he can’t provide what his son wants or needs at a given moment. “I’m trying to raise my son the best I can…he’s at such a pivotal time in his life.” Alan’s financial situation was helped for a time by Social Security Disability Insurance payments but these payments ended. He is trying to get SSDI reinstated but the process of doing so is confusing and is taking a lot of time. Alan returned to work about 11 months ago at a liquor store (after about 2 years of not being able to work), the same store where he previously worked part time while teaching. He works in the wine department. “I sell wine and make recommendations.” When asked for advice to other brain injury survivors, Alan’s words were: “No matter how confused or upset you are or how frustrated you get, keep pressing on and moving forward because there is light at the end of the tunnel even though it may seem long. Keep moving forward and don’t give up no matter what anyone says to you”. Alan added that supports for individuals with brain injury are very important. He has found support groups, retreats, and seminars/events where brain injury survivors can share their experience to be very helpful. The volunteer work he does at Craig Hospital has been valuable for him. Alan is an inspiring individual. Despite having scarce memory of his accident and some confusion about the functional losses he has experienced, Alan has worked hard to make his recovery as complete as possible. He continues to work hard to progress and to express gratitude for those who have assisted him along the way.
