Febrile seizures (FSs) are the most common convulsions in childhood. Studies have demonstrated a significant relationship between a history of prolonged FSs during early childhood and temporal sclerosis, which is responsible for intractable mesial temporal lobe epilepsy. It has been shown that interleukin-1β (IL-1β) is intrinsically involved in the febrile response in children and in the generation of FSs. We summarize the gene polymorphisms, changes of IL-1β levels and the putative role of IL-1β in the generation of FSs. IL-1β could play a role either in enhancing or in reducing neural excitability. If the enhancing and reducing effects are balanced, an FS does not occur. When the enhancing effect plays the leading role, an FS is generated. A mild imbalance can cause simple FSs while a severe imbalance can cause complex FSs and febrile status epilepticus. Therefore, anti-IL-1β therapy may help to treat FSs.
Coxsackievirus A16(CVA16) is one of major pathogens of hand, foot and mouth disease(HFMD) in children. Long non-coding RNAs(Inc RNAs) have been implicated in various biological processes,but they have not been associated with CVA16 infection. In this study, we comprehensively characterized the landscape of Inc RNAs of normal and CVA16 infected rhabdomyosarcoma(RD)cells using RNA-Seq to investigate the functional relevance of Inc RNAs. We showed that a total of 760 Inc RNAs were upregulated and 1210 Inc RNAs were downregulated. Out of these dysregulated Inc RNAs, 43.64% were intergenic, 22.31% were sense, 15.89% were intronic, 8.67% were bidirectional, 5.59% were antisense, 3.85% were s RNA host Inc RNAs and 0.05% were enhancer. Six dysregulated Inc RNAs were validated by quantitative PCR assays and the secondary structures of these Inc RNAs were projected. Moreover, we conducted a bioinformatics analysis of an Inc RNAs(ENST00000602478) to elucidate the diversity of modification and functions of Inc RNAs. In summary, the current study compared the dysregulated Inc RNAs profile upon CVA16 challenge and illustrated the intricate relationship between coding and Inc RNAs transcripts. These results may not only provide a complete picture of transcription in CVA16 infected cells but also provide novel molecular targets for treatments of HFMD.
