Zusammenfassung: | To assess the activity of allogeneic anti-CD3 antibody induced activated killer (CD3AK) cells on transplanted human renal cell cancer (RCC) in mice with severe combined immune deficiency (SCID), thus to provide theoretical and experimental support for clinical application of allogeneic CD3AK cells in the treatment of RCC.
A culture system which can massively increase allogeneic CD3AK cells was constructed. CCK-8 method was used to detect lethal effect of allogeneic CD3AK cells on human OS-RC-2 renal cancer cell line. Then, tumor-bearing mice models were constructed. SCID mice were randomly divided into four groups: group A (caudal vein was injected with allogeneic CD3AK cells before tumor bearing), group B (the control group of group A: caudal vein was injected with PBS before tumor bearing), group C (caudal vein was injected with allogeneic CD3AK cells after tumor bearing) and group D (the control group of group C: caudal vein was injected with PBS after tumor bearing), and spleen parameters were calculated to observe any inhibitory effect of allogeneic CD3AK cells on the growth of renal cancer cells, as well as their effect on the immune system of mice.
Compared with the control groups B and D, spleen parameters of groups A and C increased significantly (p0.05); compared with the control groups B and D, tumor weight of groups A and C decreased significantly and tumors grew slowly (p |
