NK cells: the immune system's first line of defense
Natural killer (NK) cells are the first line of defense of the human immune system. They can identify and destroy abnormal and early-stage cancer cells without prior sensitization, playing an irreplaceable role in tumor immune surveillance.
NK cell activity declines with age
Scientific research shows that NK cell numbers and activity gradually decline with aging, chronic stress and unhealthy lifestyle habits — one important reason behind rising cancer incidence in middle-aged and elderly populations. In recent years, immunotherapy that expands a patient's own NK cells in vitro and reinfuses them has drawn wide attention. Clinical studies indicate the therapy can effectively strengthen immune function and improve the body's ability to monitor and eliminate tumors.
Who is suitable
NK cell immune-enhancement therapy suits several groups: people with a family history of cancer seeking preventive immune care; patients in post-operative recovery; sub-health individuals with low immunity and chronic fatigue; and middle-aged and elderly people seeking immune-aging intervention. Treatment typically includes NK cell activity assessment, cell collection, in vitro expansion and reinfusion, all completed at a qualified medical institution.
MedBridge support
MedBridge can arrange NK cell activity testing and treatment evaluation at partner institutions in Shanghai, with professional accompaniment and multilingual service. Patients should first submit a recent health report so doctors can assess suitability. To learn more about indications, process and costs, consult us via live chat.
