ReviewFAIR SCI Ahead: the evolution of the Open Data Commons for preclinical spinal cord injury research (ODC-SCI.org).
Over the last 5 years, multiple stakeholders in the field of spinal cord injury (SCI) research have initiated efforts to promote publications standards and enable sharing of experimental data. In 2016, the National Institutes of Health/National Institute of Neurological Disorders and Stroke hosted representatives from the SCI community to streamline these efforts and discuss the future of data sharing in the field according to the FAIR (Findable, Accessible, Interoperable and Reusable) data stewardship principles. As a next step, a multi-stakeholder group hosted a 2017 symposium in Washington, DC entitled "FAIR SCI Ahead: the Evolution of the Open Data Commons for Spinal Cord Injury research." The goal of this meeting was to receive feedback from the community regarding infrastructure, policies, and organization of a community-governed Open Data Commons (ODC) for pre-clinical SCI research. ⋯ ODC-SCI enables data management, harmonization, and controlled sharing of data in a manner consistent with the well-established norms of scholarly publication. Specifically, ODC-SCI is organized around virtual "laboratories" with the ability to share data within each of three distinct data-sharing spaces: within the laboratory, across verified laboratories, or publicly under a creative commons license (CC-BY 4.0) with a digital object identifier that enables data citation. The ODC-SCI implements FAIR data sharing and enables pooled data-driven discovery while crediting the generators of valuable SCI data.

ReviewComplement in the development of post-traumatic epilepsy: prospects for drug repurposing.
Targeting neuroinflammation is a novel frontier in the prevention and treatment of epilepsy. A substantial body of evidence supports a key role for neuroinflammation in epileptogenesis, the pathological process that leads to the development and progression of spontaneous recurrent epileptic seizures. ⋯ Several therapeutic agents targeting the complement system are already on the market to treat other central nervous system disorders or are well advanced in their development. The purpose of this review is to summarize findings on complement activation in experimental TBI and epilepsy models, highlighting the potential of drug repurposing in the development of therapeutics to ameliorate post-traumatic epileptogenesis.

ReviewDamage mechanisms to oligodendrocytes and white matter in CNS injury: the Australian context.
Traumatic brain injury (TBI) and spinal cord injury (SCI) present a significant contribution to the global disease burden. White matter tracts are susceptible to both the physical forces of trauma and cascades of pathological secondary degeneration. Oligodendrocytes, the myelinating cells of the central nervous system (CNS), and their precursors are particularly vulnerable cell populations and their disruption results in a loss of white matter, dysmyelination, and poor myelin repair. ⋯ Neuronal and functional loss accompany dysmyelination together with an increase in astro- and microgliosis. Remyelination is often partial, and more work is needed to understand deficits in remyelination post-injury to develop strategies to both protect and repair myelin and thereby preserve function. This review covers disruptions to oligodendrocyte function and white matter tract structure in the context of TBI and SCI, with an emphasis on Australian contributions in recognition of the International Neurotrauma Symposium held in Melbourne, Australia in 2020.

ReviewThe impact of traumatic injury to the immature human brain: a scoping review with insights from advanced structural neuroimaging.
Traumatic brain injury (TBI) during critical periods of early-life brain development can affect the normal formation of brain networks responsible for a range of complex social behaviors. Because of the protracted nature of brain and behavioral development, deficits in cognitive and socioaffective behaviors may not become evident until late adolescence and early adulthood, when such skills are expected to reach maturity. In addition, multiple pre- and post-injury factors can interact with the effects of early brain insult to influence long-term outcomes. ⋯ In this review, in which we focus on contributions from Australian researchers to the field, we have highlighted pioneering longitudinal studies in pediatric TBI, in relation to social deficits specifically. We also discuss the use of advanced neuroimaging and novel behavioral assays in animal models of TBI in the immature brain. Together, this research aims to understand the relationship between injury consequences and ongoing brain development after pediatric TBI, which promises to improve prediction of the behavioral deficits that emerge in the years subsequent to early-life injury.
