The brain has very high energy demands that are mainly met by the circulating blood glucose to ensure its proper functioning. Thus, it is not surprising that though the human brain weighs only 2- 3% of the body weight, it consumes approximately 25% of tota ...
Apolipoprotein E (ApoE) is found in three different forms in humans (ApoE2, ApoE3 and ApoE4), and ApoE polymorphism is recognized as a major risk factor for Alzheimer's disease (AD). ApoE is involved in lipid and cholesterol transport, cell repair, and amy ...
The neurogenesis hypothesis of major depression has two main facets. One states that the illness results from decreased neurogenesis while the other claims that the very functioning of antidepressants depends on increased neurogenesis. In order to verify t ...
The hippocampal dentate gyrus (DG) is one of the two sites where neurogenesis continues throughout life in the mammalian brain. Accumulating evidence suggests a unique contribution of adult-generated dentate neurons in hippocampal synaptic plasticity and h ...
In the mammalian dentate gyrus (DG) neurogenesis continues throughout life. Accumulating evidence suggests a unique contribution of adult-generated neurons in DG synaptic plasticity and hippocampal-mediated learning and memory functions. However, the preci ...
Several psychobiological factors are associated with vulnerability/resilience to stress-induced depression. Emerging evidence indicates behavioral traits, such as anxiety, can be related to depression-like symptoms after exposure to chronic stress. However ...
Although neural substrates of mammalian female mating behavior have been described [1, 2], the association between complex courtship activity and specific underlying mechanisms remains elusive [3]. We have isolated a mouse line that unexpectedly shows alte ...
Intensive research is devoted to unravel the neurobiological mechanisms mediating adult hippocampal neurogenesis, its regulation by antidepressants, and its behavioral consequences. Macrophage migration inhibitory factor (MIF) is a pro-inflammatory cytokin ...
New neurons are continuously generated from neural stem cells with astrocyte properties, which reside in close proximity to the ventricle in the postnatal and adult brain. In this study we found that microRNA-124 (miR-124) dictates postnatal neurogenesis i ...
Down syndrome (DS), caused by the triplication of human chromosome 21, is the most frequent genetic cause of mental retardation. The Ts65Dn mouse model of DS show many neurological similarities to the human syndrome, including decreased hippocampal neuroge ...
