Recently, a variant in the human bdnf gene, resulting in a valine to methionine substitution in the prodomain, has been shown to lead to defective regulated secretion from neurons and memory impairment.
The met-allele of the BDNF polymorphism seems to render subjects more vulnerable for dysfunctions associated with the UF, a tract known to be related to negative emotional-cognitive processing bias, declarative memory problems, and autonoetic self awareness.
Aβ(+)ɛ4(+)/BDNF(Met) individuals can expect to show clinically significant memory impairment after 3 years, whereas Aβ(+)ɛ4(+)/BDNF(Val/Val) individuals can expect a similar degree of impairment after 10 years.
Memory impairment induced by isoflurane exposure is associated with dysregulated histone acetylation in the hippocampus, which affects BDNF expression and hence BDNF downstream signaling pathway.
These findings suggested that FDS and its constituent soyasaponins and isoflavones may attenuate memory impairment by the regulation of NF-κB-mediated BDNF expression.
Here, we characterize the behavioral deficits after HI and TH stratified by sex, as well as late changes in BDNF and its correlation with memory impairment.
Although a significant decrease of hippocampal BDNF levels underlies the learning/memory impairment induced by MK-801, this effect was not significantly prevented by Clz.
The main goal of the present study was to investigate the possible epigenetic modulation underlying recognition memory impairment and reduced BDNF levels in the hippocampus of adult maternally deprived rats.
However, the effects of PRE084 on CaMKIV-TORC1-CREB and BDNF, even for learning and memory impairment, were antagonized by the co-administration of PEAQX, an antagonist of NR2A.
Running during adolescence rescues a maternal separation-induced memory impairment in female mice: Potential role of differential exon-specific BDNF expression.
Our findings suggest that Pb exposure in e-waste recycling and dismantling areas could result in an increase in serum BDNF level and a decrease in child olfactory memory, in addition, BDNF might be involved in olfactory memory impairment.
Low- and high-intensity treadmill exercise attenuates chronic morphine-induced anxiogenesis and memory impairment but not reductions in hippocampal BDNF in female rats.
We evaluated the effect of chronic pain on the glutamate and GABA levels and BDNF expression in the CA1 region of hippocampus as a possible explanation for memory impairment related to neuropathic pain.
FTY720 (1mg/kg) administration to VPA-exposed rats (1) improved social behavior, spatial learning and memory impairment; (2) resulted in a reduction in neuronal loss and apoptosis of pyramidal cells in hippocampal CA1 regions; (3) inhibited activation of microglial cells, in turn lowering the level of pro-inflammatory cytokines interleukin-1β (IL-1β) and IL-6 in the hippocampus; (4) changed Malondialdehyde (MDA) levels, Glutathione (GSH) levels, superoxide dismutase (SOD) activity and Glutathione Peroxidase (GSH-Px) activity in the hippocampus; (6) inhibited the elevated Bax and caspase-3 protein levels and enhanced the relative expression level of Bcl-2 in the hippocampus; and (7) increased phospho-Ca2+/calmodulin-dependent protein kinase II (p-CaMKII), phospho-cAMP-response element binding protein (p-CREB) and Brain Derived Neurotrophic Factor (BDNF) protein expression in the hippocampus.
MiR-132, miR-204 and BDNF-TrkB signaling pathway may be involved in spatial learning and memory impairment of the offspring rats caused by fluorine and aluminum exposure during the embryonic stage and into adulthood.
We used the Wechsler Memory Scale-third edition (WMS-III), the presence of the <i>BDNF Val<sup>66</sup>Met</i> polymorphism, and plasma concentrations of BDNF to investigate the association between memory impairment and BDNF in BD-II disorder.
Treatment with NAD-299, TCB-2, and NAD-299 + TCB-2 attenuated the STZ-induced memory impairment in both NOR and PAL tasks. icv-STZ induced a decrease in hippocampal BDNF levels and increased Aβ plaques production in the brain, whereas treatment with NAD-299, TCB-2, and NAD-299 + TCB-2 reduced Aβ plaques in the brain and increased the hippocampal BDNF level.
Administration of memantine reversed depression-like behavior and memory impairment and significantly increased BDNF and TrkB mRNA levels in both prefrontal cortex and hippocampus of stress exposed rats.
Lack of correlation between memory impairment and levels of BDNF, magnesium and/or oxidant and antioxidant balance in the hippocampus is likely to be related to animal locomotor activity in the multiple platforms method.
We investigated the effects of moderate treadmill exercise on Aβ-induced learning and memory impairment as well as the upstream pathway responsible for increasing hippocampal BDNF in an animal model of AD.
