It is becoming increasingly clear that leptin is not only a hormone regulating energy homeostasis but also a neurotrophic factor impacting a number of brain regions, including the hippocampus. Although leptin promotes the development of GABAergic transmission in the hypothalamus, little is known about its action on the GABAergic system in the hippocampus. Here we show that leptin modulates GABA...
We have analyzed the developmental molecular programs of the mouse hippocampus, a cortical structure critical for learning and memory, by means of large-scale DNA microarray techniques. Of 11,000 genes and expressed sequence tags examined, 1,926 showed dynamic changes during hippocampal development from embryonic day 16 to postnatal day 30. Gene-cluster analysis was used to group these genes in...
In the hippocampus at birth, most glutamatergic synapses are immature and functionally "silent" either because the neurotransmitter is released in insufficient amount to activate low-affinity alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionate receptors or because the appropriate receptor system is missing or nonfunctional. Here we show that, in the newborn rat, a brief application of nicotin...
Our understanding of mechanisms that regulate the differentiation of specific classes of synapses is limited. Here, we investigate the formation of synapses between hippocampal dentate gyrus (DG) neurons and their target CA3 neurons and find that DG neurons preferentially form synapses with CA3 rather than DG or CA1 neurons in culture, suggesting that specific interactions between DG and CA3 ne...
Background: Most drugs used by pregnant women can pass through the placenta and expose embryos and developing embryos to teratogenic effects. Due to the increased cellular damage of Bax gene expression, the effect of cholorodiazepoxide use during pregnancy on Bax gene expression in the hippocampus of neonatal rats was investigated. Materials and methods: After confirmation of pregnancy in Wista...
