Abstract
SRY-related HMG box (SOX)21, one of the most highly expressed transcription inhibitors in the central nervous system (CNS), is involved in neurogenesis-related transcription and proliferation, which are associated with certain neurological disorders. However, it is the role of SOX21 in the pathogenesis of epilepsy remains unclear. In this study, our aim was to examine the expression and function of SOX21 in patients with temporal lobe epilepsy (TLE), as well as pentylenetetrazol (PTZ)-kindled rats, and to identify the possible roles of SOX21 in epileptogenesis. We found that SOX21 localized in neurons is upregulated, especially in TLE patients. SOX21 is present in the hippocampus or adjacent temporal cortex in the PTZ-kindled epileptic rat model. In addition, the P-gpMAbNano-structured material (PNM) nanoparticles carrying anti-epileptic drugs (AEDs) were injected into the epileptic model rats using an intravenous injection. The expression of tumor necrosis factor peptide in the rats was detected to verify whether the drug-carrying nanoparticles could bypass macrophages and reach the target for treatment. We also found an interaction between SOX21 and SOX2 in PTZ-kindled rats. These results indicate that SOX21 is mainly located in neurons and may regulate the pathogenesis of epilepsy, possibly in association with SOX2. Moreover, PNM nanoparticles equipped with AEDs can reach the target through macrophages in vivo, providing a new approach for the clinical treatment of epilepsy.
