Why are NK cells indispensable in the human body？

　　1. The First Line of Immune Defense

　　NK cells (natural killer cells) do not require prior training; they patrol the body 24/7， quickly identifying and eliminating cancerous and virus-infected cells.

　　2. Supporting Data： Decreased NK cell activity increases cancer risk by 2-3 times (Nature Immunology).

　　3. Core Mechanism of Anti-Aging

　　They eliminate "zombie cells，" reducing the accumulation of inflammatory factors and slowing organ degeneration.

　　They promote collagen regeneration， improving signs of aging such as loose skin and dullness.

　　The Three Major Anti-Aging Functions of NK Cells

　　Cancer Prevention and Protection： Directly kills tumor cells， reducing the risk of breast cancer， liver cancer， etc.

　　Antiviral： Has the potential to eliminate latent infections caused by viruses such as influenza and HPV.

　　Overall Rejuvenation：

　　Boosts metabolism (improves high blood sugar and fatty liver);

　　Enhances brain microcirculation， preventing neurodegenerative diseases.
