The survival time of immune cells in the body after reinfusion depends on several factors, including the type of cell, health status, environment after reinfusion, and individual differences. In general, healthy immune cells survive relatively long in the body, while immune cells affected by disease may survive for a shorter period of time.
After the immune cells are reinfused, they first need to pass through the blood circulation to reach their destination, and this process takes a certain amount of time. After arriving at their destination, immune cells need to adapt to the new environment and interact with the original immune cells to exert their immune effects. During this process, some immune cells may die because they do not adapt to the environment or are attacked, while others will survive in the body for a long time.
Studies have shown that some healthy immune cells, such as dendritic cells and T cells, can survive for months or even years in the body. And some immune cells affected by the disease, such as tumor cells or cells infected with viruses, may have a shorter survival time. In addition, some drugs or methods may also affect the survival time of immune cells.
It is important to note that immune cell reinfusion is not a foolproof method, and its effectiveness and safety depend on several factors. Therefore, a thorough evaluation and consultation is required prior to immune cell reinfusion to ensure efficacy and safety. At the same time, the study of the survival time and mechanism of immune cells also needs to be further deepened to better understand and apply this method.
