AbstractIn the intact CNS platelets are separated from the neurons and glial cells by the blood-brain barrier (BBB) structure. However, during pathological condition such as the trauma, infection, neurodegeneration, inflammation BBB become compromised leading to direct interaction of neurons with platelets. We have previously found that brain-specific sialated gangliosides within neuronal lipid rafts directly activated platelets. Here we plan to investigate the possible role of platelet-lipid raft interactions in the modulation of neuronal activity in mouse model of epilepsy. We found that the seizure durations were significantly reduced in wild-type (WT) mice with depleted platelets. At the same time, ST3-deficient mice, which lack of brain-specific gangliosides in neuronal lipid rafts, had lower levels of peak seizures with lower mortality rate when compared with WT controls. The activity of neurons was increased when neuronal cells were co-incubated with platelets, both in primarily neural culture and in brain slice organotypic cultures. Thus, we expect to elucidate particular molecular mechanisms how integration of platelets with neuronal lipid rafts modulate neuronal functions and promote seizures.
