Summary
Alzheimer's disease (AD) prevalence is rising and there is no curative treatment. Neurotoxic amyloid-beta peptide and concomitant lipid oxidation in the brain contribute to the cause of AD. We have identified a new pathway by which a protein called apoD may inhibit lipid oxidation in the AD brain. We will test the impact that changing apoD levels in neurons and in genetically modified mice has on neuron stress and AD-like characteristics. This may reveal new avenues to prevent or treat AD.

Summary
ApoD is a highly conserved lipocalin known for its antioxidant nature and role in regulation of inflammation. Oxidative stress and neuroinflammation are known to play a critical role in dementia. This project will study the association of apoD to inflammatory and oxidative stress markers in Alzheimer’s disease and Frontotemporal Dementia, two major forms of dementia. It will also examine the impact of apoD on disease pathology. Hence this project will lead us to therapeutic potentials of apoD.

Summary
It is well known that high levels of cholesterol in blood cause coronary heart disease. It is also known that not all of the cholesterol in blood is bad. Whereas the cholesterol carried in particles called low density lipoproteins (LDLs) causes heart disease, other cholesterol carriers in blood known as high density lipoproteins (HDLs) actually protect against the development of heart disease. However, HDLs include several different populations of particles, only some of which are protective. On ....It is well known that high levels of cholesterol in blood cause coronary heart disease. It is also known that not all of the cholesterol in blood is bad. Whereas the cholesterol carried in particles called low density lipoproteins (LDLs) causes heart disease, other cholesterol carriers in blood known as high density lipoproteins (HDLs) actually protect against the development of heart disease. However, HDLs include several different populations of particles, only some of which are protective. One determinant of the ability of HDLs to protect against coronary heart disease is their protein composition. This project investigates how the protein composition of HDL populations influences their structure, function and metabolism. It is also concerned with understanding what regulates the relative concentrations of the different HDL populations. The studies of HDL structure, function and metabolism will allow us to understand why the different HDL populations differ in their abilities to protect against heart disease. The regulation studies will tell us how to go about designing therapies to increase the levels of those HDL populations that do protect.Read moreRead less
