Abstract | Previous studies have demonstrated that inflammation plays a critical role in hippocampcal damage and cognitive dysfunction induced by convulsive status epilepticus (CSE). Emerging evidence indicated that the long non-coding RNA (lncRNA) H19 acts as an important regulator of inflammation in various diseases. However, the role of H19 in CSE is still unkonwn. In the present study, pilocarpine-induced SE rat model was used to explore the role of H19 in hippocampal neuron damage in CSE. Our results indicated that the increased level of H19 is positively correlated with the expression of inflammatory cytokines (TNF-α and IL-1β) in hippocampus of SE rats. Moreover, knockdown of H19 could inhibit the activation of microglia and suppress the expression of inflammatory cytokines via nuclear factor-kappaB (NF-κB) signaling pathway. It was further revealed that downregulation of H19 could alleviate hippocampal neuron damage induced by CSE. These findings indicated that H19 modulates inflammatory response and hippocampal damage through the NF-κB signaling pathway in the CSE rats, which provides a promising target to alleviate hippocampcal damage of CSE. |
