Behavioral Aspects Of Apolipoprotein E Knockout Mice, Melissa T. Litherland

Masters Theses

Apolipoprotein E (apoE) is a lipid transporting protein that has been shown to play a vital role in nerve repair and remodeling. Previous studies have shown that apoE is highly expressed in human and mouse olfactory bulbs. ApoE deficiency in apolipoprotein E knockout (apoE-KO) mice leads to considerable delay in olfactory nerve repair and deficits in olfactory functioning. Olfactory function is necessary for a number of social behaviors in mice. Loss of olfaction can greatly reduce social behaviors. Since apoE-KO mice display olfactory dysfunction, this deficit may result in alterations in social behavior. Olfactory function was assessed in apoE-KO mice …

Cell Biology Of Apoe In Cortical Cultured Neurons: Possible Roles In Alzheimer's Disease, Anna G. Barsukova

Masters Theses

The apolipoprotein E4 (apoE4) genotype is a major risk factor for Alzheimer's disease (AD). Previous studies have shown that apoE4 is less effective than apoE3 in supporting neurite outgrowth in adult mice cortical cultures. However the mechanism underlying this phenomenon is not known. To understand this mechanism and the broader role of apoE isoforms on neuronal biology I examined the rate of apoE isoforms internalization in neurons, effects of apoE isoforms on lipid uptake by neurons, effects of apoE isoforms on neuronal environment - microglia and on neuroregeneration, or neurogenesis.

I examined the binding and internalization of recombinant human apoE3 …
