ABSTRACT
Background:In recent years a number of potential synapto-nuclear protein messengers have been characterized that are thought to be involved in plasticity-related gene expression, and the capacity importin-mediated activitydependent nuclear import.However, there is surprising paucity data showing import such proteins cellular models learning memory.Only recently it was found transcription factor cyclic AMP response element binding 2 (CREB2) transits nucleus during long-term depression (LTD), but not potentiation (LTP) synaptic transmission hippocampal primary neurons.Jacob another messenger couples NMDA-receptor-activity expression.We therefore aimed study whether Jacob accumulates physiological relevant activity-dependent plasticity.Methodology/Principal Findings: We analyzed dynamics Jacob's following induction NMDAreceptor dependent LTP or LTD at Schaffer collateral-CA1 synapses rat slices.Using time-lapse imaging neurons expressing Jacob-Green-Fluorescent-Protein we rapidly translocates from dendrites already tetanization period LTP, after LTD.Immunocytochemical stainings confirmed accumulation endogenous comparison apical LTD.Complementary findings were obtained NMDA-receptor chemical neurons.However, accordance with previous studies, high concentrations NMDA glycine as well specific activation extrasynaptic NMDA-receptors resembling pathological conditions induce an even more profound increase levels.Conclusions/Significance: Taken together, these suggest two major forms plasticity, LTD, elicit transition different albeit both cases importinmediated retrograde transport required.
