Ochrona mózgu w epilepsji u dzieci poprzez działanie na układ dopełniacza i mikroglii

Neuroprotection in childhood developmental and epileptic encephalopathies may require approaches, distinct from adult brain injury models of neuroprotection, with a primary focus on preservation of synaptic density rather than prevention of cellular necrosis. There is growing evidence to indicate early-life seizures activate complement cascade proteins C1q and C3. Subsequently, localized microglia may excessively phagocytose structurally intact synaptic neurons disrupting normal brain maturation. This review incorporates kinetic models of neuro-immune interactions based on human histopathology from epileptogenic tissues and quantitative neuro-immune biomarkers to provide suggestions that complement-mediated synaptic pruning may contribute to structural network disruption and cognitive decline in pediatric epilepsy. While standard anti-seizure medications effectively stabilize electrical activity, they do not mitigate underlying neuro-inflammatory responses. Consequently, targeted pharmacological inhibition of the complement microglia axis may provide a potential disease modifying strategy to protect developing neural circuits. The translational feasibility of using targeted complement inhibitors should be evaluated addressing critical challenges such as central nervous system drug delivery across the blood-brain barrier, immunosuppression management and the application of non-invasive biomarkers to define the precise therapeutic window for intervention.
