Objectives:
Growth factor receptors on the tumor cells are known to be expressed highly allo
wing the tumor cells to bind growth factors to stimulate cellular division. Immu
notoxin therapy is one of the novel approaches to the primary malignant brain tu
mor, and expression of cell-surface receptor is essential for the immunotoxin to
have specific anti-tumor activity. Despite promising cytotoxic activity of immu
notoxin, tumor responses are not curative on clinical trials, and additional stu
dies are needed regarding various factors influncing the efficacy of the immunot
oxin. The purpose of this study is to detect the expression of various growth fa
ctor receptors on brain tumor cell lines which are going to be used in these stu
dies.
Materials and Methods:
The authors detected transferrin receptor(TR), insulin-like growth factor-1 rece
ptor(IGF-1R), and interleukin-4 receptor(IL-4R) on medulloblastoma cell line(Dao
y) and glioblastoma cell lines(U373 MG and T98 G) by flow cytometric analysis.
Results:
TR was expressed on Daoy, U373 MG, and T98 G. IGF-1R was expressed on Daoy and U
373 MG, but not on T98 G. IL-4R was expressed on all cell lines tested.
Conclusion:
The transferrin and interleukin-4 receptors might be good targets for immunotoxi
n therapy. The results should be considered in addition and in vitro and in vivo
studies regarding immunotoxin and in establishing the proper treatment model of
the immunotoxin therapy including selection of the adequate immunotoxin.
