Defective neuronal sprouting by human apolipoprotein E4 is a gain-of-negative function.
The apolipoprotein E (apoE) epsilon 4 allele (apoE4) is a major risk factor for neurodegenerative conditions, including Alzheimer's disease (AD). A role for apoE in regeneration of synaptic circuitry after neural injury has been shown in several in vitro studies in which apoE3 supports neuronal sprouting better than apoE4. We evaluated sprouting in an in vitro mouse organotypic hippocampal slic...
متن کاملApolipoprotein E4 domain interaction occurs in living neuronal cells as determined by fluorescence resonance energy transfer.
Apolipoprotein (apo) E4 is a major risk factor for Alzheimer disease. Although the mechanisms remain to be determined, the detrimental effects of apoE4 in neurobiology must be based on its unique structural and biophysical properties. One such property is domain interaction mediated by a salt bridge between Arg-61 in the N-terminal domain and Glu-255 in the C-terminal domain of apoE4. This inte...
متن کاملNeuronal apoptosis by apolipoprotein E4 through low-density lipoprotein receptor-related protein and heterotrimeric GTPases.
The epsilon4 genotype of apolipoprotein E (apoE4) is the most established predisposing factor in Alzheimer's disease (AD); however, it remains unclear how apoE4 contributes to the pathophysiology. Here, we report that the apoE4 protein (ApoE4) evokes apoptosis in neuronal cells through the low-density lipoprotein receptor-related protein (LRP) and heterotrimeric GTPases. We examined neuron/neur...
متن کاملAltered cholesterol metabolism in human apolipoprotein E4 knock-in mice.
Thevarepsilon4 allele of apolipoprotein E (apoE) is associated with an increased risk of developing Alzheimer's disease (AD). To accurately determine the isoform-specific effects of human apoE on brain functions under physiological and pathological situations, we created mice expressing human apoE4 isoform in place of mouse apoE by utilizing the gene-targeting technique on the embryonic stem ce...
متن کاملApolipoprotein E4 is associated with primary localized cutaneous amyloidosis.
Apolipoprotein E (apoE) is a lipid transport protein, which is a component of lipoproteins, such as very low density lipoprotein, intermediate density lipoprotein, high density lipoprotein, and chylomicron. ApoE is also produced and secreted in the skin, and is implicated to play roles in epidermal differentiation and proliferation (Barra et al, 1994). We have reported that apoE was a component...
