Function

Lipoprotein Lipase (LPL) is a key enzyme in lipid metabolism that hydrolyzes triglycerides in circulating lipoproteins, primarily chylomicrons and very-low-density lipoproteins (VLDL). It is anchored to the endothelial surface of capillaries via heparan sulfate proteoglycans, where it releases fatty acids for tissue uptake [1]. [@cellular2018]

In the central nervous system, LPL is expressed by [neurons](/entities/neurons), [astrocytes](/entities/astrocytes), and [microglia](/cell-types/microglia-neuroinflammation). It plays important roles in: [@therapeutic2017]

• Brain lipid homeostasis: Providing energy through fatty acid oxidation
• Synaptic function: Supporting membrane lipid composition
• Myelin maintenance: Delivering lipids for myelin sheath integrity
• Neuroprotection: Modulating inflammation and oxidative stress [2]

Disease Associations

Alzheimer's Disease

• Epidemiological studies have linked LPL variants to AD risk, with certain polymorphisms showing protective effects [3]
• LPL activity is reduced in AD brain tissue, potentially contributing to impaired lipid metabolism and amyloid processing [4]
• The LPL S474 variant is associated with reduced AD risk in some cohorts [5]
• Dysregulated lipid metabolism is a recognized feature of AD pathogenesis [6]

Vascular Dementia

• LPL dysfunction contributes to cerebrovascular disease through effects on triglyceride metabolism [7]
• Elevated triglycerides are a risk factor for vascular cognitive impairment [8]

Parkinson's Disease

• Some studies suggest LPL variants may influence PD risk, potentially through lipid homeostasis [9]

Expression

• Brain: LPL is expressed in neurons (especially in [hippocampus](/brain-regions/hippocampus) and cortex), astrocytes, and microglia
• Regional Distribution: High expression in the hippocampus, cerebral [cortex](/brain-regions/cortex), and basal ganglia
• Upregulation: Induced during demyelination and in response to neuronal injury
• Cellular Localization: Secreted enzyme, anchored to cell surfaces and extracellular matrix
