In addition, the latency to onset of kainic acid-induced seizures was significantly shortened in Kv4.2 heterozygous mice compared with wildtype littermates, which was accompanied by a significant increase in theta power. By contrast, overexpressing Kv4.2 in wildtype mice through intrahippocampal injection of Kv4.2-expressing lentivirus delayed seizure onset and reduced EEG power. These results suggest that Kv4.2 is an important regulator of neuronal network excitability and dendritic spine morphology, but not anxiety-related behaviors. In the future, manipulation of Kv4.2 expression could be used to alter seizure susceptibility in epilepsy.Peripheral nerve injuries can significantly reduce quality of life. While some recover, most do not recover fully, resulting in neuropathic pain and loss of sensation and motor function. Research on the mechanisms of peripheral nerve regeneration could elucidate poor patient outcomes and potential treatments. This study was designed to determine if brain derived neurotrophic factor (BDNF) is necessary for pudendal nerve regeneration and functional recovery. Peripheral administration of tyrosine kinase B functional chimera (TrkB) was used to inhibit the BDNF regenerative pathway. Female Sprague-Dawley rats received tyrosine kinase B functional chimera (TrkB) or saline after a pudendal nerve crush (PNC) or Sham PNC and were divided into three groups Sham PNC, PNC + Saline, and PNC + TrkB. Seven days after injury, relative βII tubulin expression (1.0 ± 0.2) was significantly decreased after PNC + TrkB compared to PNC + saline (2.9 ± 1.0). Three weeks after injury, BDNF plasma concentration (1320.8 ± 278.1 pg/ml) was significantly reduced in PNC + TrkB compared to PNC + saline rats (2053.4 ± 211.0 pg/ml).
