NAD⁺ metabolism-based immunoregulation and therapeutic potential

Area of Science:

• Biochemistry
• Immunology
• Metabolic pathways

Background:

• Nicotinamide adenine dinucleotide (NAD+) is a crucial metabolite involved in energy metabolism.
• NAD+ acts as a cosubstrate for enzymes like sirtuins, CD38, and PARPs.
• NAD+ metabolism influences immune cell function and inflammatory processes.

Purpose of the Study:

• To review the fundamental biochemistry of NAD+.
• To explore the roles of NAD+ in immune responses.
• To discuss the therapeutic potential of NAD+ for inflammatory diseases.

Main Methods:

• Literature review of NAD+ biochemistry and immunology.
• Analysis of NAD+ metabolism in immune cells.
• Discussion of current challenges and future directions in NAD+ research.

Main Results:

• NAD+ is essential for both innate and adaptive immune cell functionality.
• NAD+ metabolism directly impacts inflammatory responses.
• Dysregulation of NAD+ is implicated in various immunological diseases.

Conclusions:

• NAD+ bioavailability is a key target for modulating immune responses.
• Targeting NAD+ metabolism holds promise for developing novel therapeutics for inflammatory conditions, including COVID-19.
