Differential expression of suppressors of cytokine signaling-1, -2, and -3 in the rat hippocampus after seizure: implications for neuromodulation by gp130 cytokines.

Numerous studies have investigated the expression of various cytokine families in the CNS after brain injury. The gp130 or interleukin (IL)-6-type cytokines have received a great deal of focus, and it is clear that they exhibit an acute and robust upregulation in various brain injury models. We are interested to determine, however, whether endogenously expressed cytokines in the CNS act in a direct neuromodulatory manner. In an accompanying study, we examined the expression of five gp130 cytokines and their receptors in the lithium-pilocarpine model of status epilepticus. We follow up that study here by trying to determine if gp130 signal transduction occurs in hippocampal principal neurons…

Spatiotemporal distribution of gp130 cytokines and their receptors after status epilepticus: comparison with neuronal degeneration and microglial activation

Although numerous studies have demonstrated the neurotrophic capacity of gp130 cytokines, it remains unclear whether endogenously expressed cytokines actually function in a direct neuromodulatory manner. Therefore, using the lithium-pilocarpine status epilepticus model, we performed a detailed in situ hybridization time-course study of five gp130 cytokines (interleukin [IL]-6, leukemia inhibitory factor [LIF], IL-11, oncostatin-m [OSM], and ciliary neurotrophic factor), gp130, and the receptors of the cytokines we found to be induced (IL-6 receptor [IL-6R], LIF receptor [LIF-R], and IL-11 receptor [IL-11R]). Additionally, to further understand the regulation of these cytokines, we compared …
