We describe a Flippase-induced intersectional Gal80/Gal4 repression (FINGR) method, allowing tissue-specific FLP to determine Gal80 expression patterns. Wherever Gal4 and FLP overlap, Gal4 expression is turned on (Gal80 flipped out) or off (Gal80 flipped in). The FINGR method is versatile for clonal analysis and neural circuit mapping.

An injury paradigm using the Drosophila larval ventral nerve cord to investigate central nervous system regeneration and repair is described. Stabbing followed by laser scanning confocal microscopy in time-lapse and fixed specimens, combined with quantitative analysis with purposefully developed software and genetics, are used to investigate the molecular mechanisms of CNS regeneration and repair.

The video demonstrates the use of a High-Impact Trauma (HIT) device to induce closed-head traumatic brain injury (TBI) in Drosophila. TBI causes mechanical brain trauma affecting neuronal function, which over time leads to neurodegeneration and mortality.

The rodent retina has long been recognized as an accessible window to the brain. In this technical paper we provide a protocol that employs the mouse model of oxygen-induced retinopathy to study the mechanisms that lead to failure of vascular regeneration within the central nervous system after ischemic injury. The described system can also be harnessed to explore strategies to promote regrowth of functional blood vessels within the retina and CNS.
FAQs
After axons or neural circuits are disrupted, the tissue mounts a coordinated response rather than producing a single isolated change. Neurons may undergo degeneration, while glia become activated, remove cellular debris, and participate in tissue remodeling. Studying these events together helps investigators relate the initial structural disruption to later changes in neural organization and function.
Glial activation provides a cellular response that can be examined alongside neuronal degeneration. Activated glia participate in clearing debris generated by damaged neural tissue and contribute to remodeling within the injured region. Measuring these activities helps researchers determine how non-neuronal cells shape the tissue environment after trauma and whether their responses align with changes in neural function.
Genetic tractability allows researchers to manipulate specific pathways while observing how injured nervous tissue responds. This makes the system useful for connecting candidate genes or pathways with degeneration, repair, and neuroprotection. Because injury-response pathways are conserved, targeted genetic experiments can also provide broader insight into mechanisms relevant to nervous-system trauma.
Two approaches identified for this model are axotomy and physical injury. Axotomy specifically disrupts axons, whereas physical injury produces damage to nervous tissue more broadly. After applying the selected injury, researchers can compare structural responses, neuronal degeneration, glial activity, and functional consequences to determine how the type of trauma influences the observed outcome.
Behavioral analysis, microscopy, and targeted genetic manipulation provide complementary information. Microscopy reveals cellular and tissue changes, behavioral assays indicate how those changes affect neural function, and genetic manipulation tests the contribution of selected pathways. Using these measurements together helps link injury-induced molecular or cellular responses with observable changes in the organism.
The model supports genetic screens for mechanisms of neurodegeneration, repair, and neuroprotection. It also enables rapid evaluation of candidate pathways and interventions by combining controlled injury with cellular and behavioral analysis. In neuroscience research, this approach helps prioritize mechanisms that alter the response to trauma and may clarify how conserved injury pathways influence nervous-tissue outcomes.
