Abstract:
Accumulating evidence indicates that p38 mitogen-activated protein kinase (MAPK) could play more than one role in Alzheimer's disease (AD) pathophysiology and that patients suffering from AD dementia could benefit from p38 MAPK inhibitors. The p38 MAPK signalling has been widely accepted as a cascade contributing to neuroinflammation. However, deepening insight into the underlying biology of Alzheimer's disease reveals that p38 MAPK operates in other events related to AD, such as excitotoxicity, synaptic plasticity and tau phosphorylation. Although quantification of behavioural improvements upon p38 MAPK inhibition and in vivo evaluation of p38 MAPK significance to various aspects of AD pathology is still missing, the p38 MAPK is emerging as a new Alzheimer's disease treatment strategy. Thus, we present here an update on the role of p38 MAPK in neurodegeneration, with a focus on Alzheimer's disease, by summarizing recent literature and several key papers from earlier years.
Insights
p38 mitogen-activated protein kinase (MAPK) is implicated in Alzheimer's disease (AD) beyond neuroinflammation, affecting excitotoxicity and synaptic plasticity. Inhibiting p38 MAPK shows promise as a novel therapeutic strategy for AD dementia.
Area of Science:
- Neuroscience
- Molecular Biology
- Pharmacology
Background:
- p38 mitogen-activated protein kinase (MAPK) signaling is a known contributor to neuroinflammation in Alzheimer's disease (AD).
- Emerging research highlights p38 MAPK's involvement in other AD-related processes, including excitotoxicity, synaptic plasticity, and tau phosphorylation.
- Despite its multifaceted roles, a comprehensive understanding and in vivo validation of p38 MAPK's significance in AD pathology are still developing.
Purpose of the Study:
- To provide an updated review on the role of p38 MAPK in neurodegeneration, specifically focusing on Alzheimer's disease.
- To summarize recent literature and key earlier studies concerning p38 MAPK in AD pathophysiology.
- To highlight the potential of p38 MAPK inhibitors as a therapeutic strategy for AD dementia.
Main Methods:
- Literature review and synthesis of recent and seminal research papers.
- Analysis of studies investigating p38 MAPK signaling pathways in the context of Alzheimer's disease.
- Focus on summarizing evidence related to neuroinflammation, excitotoxicity, synaptic plasticity, and tau phosphorylation.
Main Results:
- p38 MAPK signaling is implicated in multiple facets of Alzheimer's disease pathology, not solely neuroinflammation.
- Evidence suggests p38 MAPK influences excitotoxicity, synaptic plasticity, and tau phosphorylation, key events in AD.
- While direct quantification of behavioral improvements and in vivo evaluations are ongoing, p38 MAPK inhibitors are emerging as a potential treatment avenue.
Conclusions:
- p38 MAPK plays a complex and significant role in Alzheimer's disease pathogenesis.
- Targeting p38 MAPK represents a promising therapeutic strategy for managing Alzheimer's disease dementia.
- Further research is warranted to fully elucidate the in vivo effects and clinical benefits of p38 MAPK inhibition in AD.
