Vitamin K: Infection, Inflammation, and Auto-Immunity

Area of Science:

• Biochemistry
• Immunology
• Nutritional Science

Background:

• Vitamin K (VK), including VK1 and VK2, is known for its role in blood coagulation.
• Emerging research highlights VK's broader impact on immunity, antioxidant capacity, and gut health.
• VK's influence extends to epithelial development and bone protection.

Purpose of the Study:

• To review the mechanisms of action for Vitamin K.
• To explore the potential preventive and therapeutic applications of VK in various diseases.
• To examine the role of VK-dependent proteins (VKDPs) in inflammation and immunity.

Main Methods:

• Literature review of existing research on Vitamin K.
• Analysis of studies focusing on VK's effects on infections, inflammation, and autoimmune disorders.
• Examination of the role of VK-dependent proteins (VKDPs) in immune modulation.

Main Results:

• Vitamin K demonstrates potential in managing infections like asthma and COVID-19.
• VK shows promise in addressing inflammatory conditions such as type 2 diabetes, Alzheimer's, Parkinson's, cancer, aging, and atherosclerosis.
• VK is implicated in the prevention and treatment of autoimmune disorders including IBD, type 1 diabetes, MS, and rheumatoid arthritis.
• VK-dependent proteins (VKDPs) are key mediators of VK's anti-inflammatory and immunomodulatory effects.

Conclusions:

• Vitamin K presents a promising therapeutic agent for clinical applications in infections, inflammation, and autoimmune diseases.
• Further research is essential to fully elucidate VK's mechanisms of action and address current therapeutic limitations.
• VK's role in preventing aging and treating neurological disorders warrants continued investigation.
