The Effect of CD3AK Cells on T Lymphocyte Subsets and Its Functions of Patients with Primary Liver Carcinoma

Objective To explore the effect of CD3AK cells on T lymphocyte subsets and its functions of patients with primary liver carcinoma (PLC). MethodsFiftyeight patients with PLC were divided into two groups, CD3AK group (n=37), control group (n=21). Eleven blood donors were taken as normal control. All patients from the treatment group were given 2×109 CD3AK cells once a day for 5 days on the 1st day after operation, having received IL2 at a dose of 100 units per 24 hour by intravenous injection starting 30 minutes before administration of CD3AK cells. T lymphocyte subsets, IL2R, NK activity, LAK activity and proliferative activity were determined. ResultsThe CD4/CD8 ratio, expression of IL2R, proliferative activity, NK activity and LAK activity of T lymphocytes from the treatment group were significantly higher than those of control respectively.Conclusion The adoptive transfer of CD3AK cells could improve the disorder of T lymphocyte subsets and its functions and provide the patients with PLC with fresh abundant effectors against tumor.
