What is immunocyte therapy?                                                    

Immune cells are commonly known as white blood cells, including lymphocytes, dendritic cells, macrophages, etc. They form the immune force of the human body. 
It has immune defense, immune stabilization and immune surveillance functions, responsible for eliminating bacteria, viruses and cancer cells, and ensuring the healthy operation of the body's functions. 
Immune cell therapy refers to the process of collecting the patient's own immune cells, activating and expanding them in the laboratory, and then reinfusing them back into the body. 
This enables the development of treatment methods that enhance the human immune system's ability to recognize, activate the immune defense mechanism, and quickly eliminate diseased or abnormal cells (such as cancer cells, infected cells).

NK细胞（Natural killer cell）

NK (Natural Killer)细胞，即自然杀伤细胞，是人体免疫系统的重要组成部分，负责对抗病毒感染和癌细胞，被誉为人体免疫系统的“第一道防线”。

自然杀伤能力:无需特定抗原识别便可直接攻击或杀死体内异常细胞或癌变细胞。

细胞毒性因子:拥有穿孔素和颗粒酶等细胞毒性因子,用于破坏靶细胞。

NK细胞的核心功能

抗癌作用

无需预先激活即可直接识别并杀伤肿瘤细胞。

抗病毒与抗感染

对多种病毒(如乙肝病毒、HPV)感染具有清除能力,帮助控制慢性感染。

抗衰老

直接杀伤异常衰老细胞。

免疫调节

NK细胞与其他免疫细胞(例如巨噬细胞和T细胞)协同工作,增强机体的防御机制。

NK细胞的杀伤力                                                          NK细胞的活力

活化的NK细胞比活化的γδT细胞或活化的αβT细胞更能有效地杀死癌细胞                             NK细胞对癌细胞的杀伤活性提高了几倍到几十倍。
