Abstract
Epilepsy is a common neurological disease caused by synchronous firing of hyperexcitable neurons. Currently, patients with epilepsy are typically treated with antiseizure medicines that work by interrupting the hyperexcitability or hypersynchrony of localized neurons or by inhibiting excitatory neurotransmission. However, these drugs do not treat the underlying causes of epilepsy, and nearly one-third of patients have seizures that cannot be controlled by these medications. Animal and clinical evidence suggests that inflammation caused by neuronal and non-neuronal cells within the epilepsy lesion could play a central role in seizure disorders. Here we report a gas-filled nanobubble (NB) conjugated with diammonium glycyrrhizinate (DG) drugs and sphingosine-1-phosphate (S1P) molecules (S1P@DG-NBs) on the lipid shell for targeted therapy and real-time ultrasound visualization applications against neuroinflammatory injury. Affinity of S1P@DG-NBs for the S1P receptor endows these NBs with enhanced targeting capability to the neuroinflammatory microenvironment of epilepsy, where the DG drugs modulate endothelium-microglia-neuron inflammation by inhibiting high-mobility group box 1 molecules and downregulating the Toll-like receptor 4 signaling pathway, resulting in anti-inflammatory M2 microglia that exert anti-epilepsy effects. Our results show that this technology can enhance visualization of epileptic brain and deliver drugs with anti-inflammatory and immunomodulatory properties to ameliorate seizures symptoms.
