NAMPT as a Therapeutic Target against Stroke

Area of Science:

• Biochemistry
• Neuroscience
• Metabolic pathways

Background:

• Nicotinamide phosphoribosyltransferase (NAMPT) is an enzyme crucial for NAD+ synthesis.
• NAD+ is vital for energy metabolism and sirtuin signaling, a key cellular defense system.
• NAMPT's role in NAD+ homeostasis suggests potential therapeutic applications.

Purpose of the Study:

• To review the therapeutic potential of NAMPT in ischemic stroke treatment.
• To explore the molecular mechanisms underlying NAMPT's neuroprotective and regenerative effects.
• To discuss translational strategies for stroke salvage and rehabilitation.

Main Methods:

• In vivo and in vitro studies on neural cells, endothelial progenitor cells, and neural stem cells.
• Exploration of molecular pathways involving NAMPT, NAD+, and sirtuin signaling.
• Review of therapeutic interventions including NMN, NAMPT activators, and ischemic conditioning.

Main Results:

• NAMPT demonstrates cerebroprotection in acute ischemic stroke phases.
• NAMPT promotes vascular repair and neurogenesis in chronic stroke phases.
• NMN, NAMPT activators, and ischemic conditioning show promise for stroke treatment.

Conclusions:

• NAMPT is a significant therapeutic target for ischemic stroke.
• Targeting the NAMPT pathway offers dual benefits in acute and chronic stroke phases.
• Further translational research is warranted to optimize NAMPT-based stroke therapies.
