objective: infection with herpes simplex virus type 1 induces viral latency in neuron trigeminal ganglions. the late associated transcript (lat) is uniquely expressed in infected neural cells, however no coding protein associated with these transcripts has been identified in infected cells. it has been shown that six micrornas transcribed from lat have the capabilities to affect the cell signal...

introduction: although tolerance to and dependence on opioids are characterized by excessive activity of camp pathway in some brain stem nuclei, the impact of morphine dependence on activity of camp pathway in paragigantocellularis nucleus (pgi), located in the rostral ventrolateral medulla, remains unclear. therefore, the effect of adenyl cyclase activator forskolin on spontaneous firing rate ...

Abstract Background & aim: Kynurenine pathway (KP) plays an important role in the pathogenesis of neuroinflammation and neurodegenerative disorders. In neurodegenerative diseases (NDD) such as Parkinson's disease (PD), Alzheimer's disease (AD), Huntington's disease (HD) and Multiple sclerosis (MS), brain neurons are initially involved and gradually disappear. In the present review article, the ...
