Abstract

Hypoxia-inducible factor 1α (HIF-1α) is a crucial transcription factor that regulates cellular responses to low oxygen levels (hypoxia). In Alzheimer’s disease (AD), emerging evidence suggests a significant involvement of HIF-1α in disease pathogenesis. AD is characterized by the accumulation of amyloid-beta (Aβ) plaques and neurofibrillary tangles (NFTs), leading to neuronal dysfunction and cognitive decline. HIF-1α is implicated in AD through its multifaceted roles in various cellular processes. Firstly, in response to hypoxia, HIF-1α promotes the expression of genes involved in angiogenesis, which is crucial for maintaining cerebral blood flow and oxygen delivery to the brain. However, in the context of AD, dysregulated HIF-1α activation may exacerbate cerebral hypoperfusion, contributing to neuronal damage. Moreover, HIF-1α is implicated in the regulation of Aβ metabolism. It can influence the production and clearance of Aβ peptides, potentially modulating their accumulation and toxicity in the brain. Additionally, HIF-1α activation has been linked to neuroinflammation, a key feature of AD pathology. It can promote the expression of pro-inflammatory cytokines and exacerbate neuronal damage. Furthermore, HIF-1α may play a role in synaptic plasticity and neuronal survival, which are impaired in AD. Dysregulated HIF-1α signaling could disrupt these processes, contributing to cognitive decline and neurodegeneration. Overall, the involvement of HIF-1α in various aspects of AD pathophysiology highlights its potential as a therapeutic target. Modulating HIF-1α activity could offer novel strategies for mitigating neurodegeneration and preserving cognitive function in AD patients. However, further research is needed to elucidate the precise mechanisms underlying HIF-1α dysregulation in AD and to develop targeted interventions.
