Abstract

Alzheimer's disease (AD) is a chronic neurodegenerative condition characterized by progressive memory loss. Mutations in genes involved in the production of amyloid-β (Aβ) are linked to the early-onset variant of AD. However, the most common form, sporadic AD, is considered to be the result of an interaction between environmental risk factors and various genes. Among them, recent work has highlighted the potential role that the 12/15-lipoxygenase (12/15LO) pathway may play in AD pathogenesis. 12/15LO is widely distributed in the central nervous system, and its levels are upregulated in patients with AD or mild cognitive impairments. Studies using animal models have implicated 12/15LO in the molecular pathology of AD, including the metabolism of Aβ and tau, synaptic integrity, and cognitive functions. We provide an overview of this pathway and its relevance to AD pathogenesis, discuss the mechanism(s) involved, and provide an assessment of how targeting 12/15LO could lead to novel AD therapeutics.

Keywords: 12/15-lipoxygenase; Alzheimer's disease; amyloid β; behavior; synapse; tau protein; therapeutics; transgenic mouse models.
