ABSTRACT
Objective:
To research the imumunological effect of dendritic cell transfected by recombinant plasmid of ΔNp73αon breast cancer.Methods:
Cultivate dendritic cells by cytokines( GM-CSF,IL-4,TNF-α) from human umbilical cord blood in vitro, CD1a,CD83 were detected by flow cytometry.Recombinant plasmid pcDNA-HA/ΔNp73αwas used to transfected DCs,the transfection was detected by Western blot.Transfected DCs cocultivate with T cell induce specific cytotoxic lymphocytes( CTL).Proliferation ability of T cell was detected by MTT methods.IFN-γin the culture supernatant of the transfected DCs were detected by ELISA.The killing effect on breast cancer MDA-MB-231 was detected by LDH method.Results:
The expression of CD1a(56%),CD83(74%)in mature DC was higher than immature DC(CD1a 19%,CD83 13%)(P<0.01).ΔNp73αtransfected group had a special band.The killing effect of specific CTL induced byΔNp73α-DC and T cells cocultivation on breast cancer cell MDA-MB-231 was statistic stronger than DC group(P<0.05),the proliferation of T cell and secretion level of IFN-γcompared with DC and pcDNA group were statistically significant(P<0.01).Conclusion:
The CTL induced byΔNp73αtransfected DC vaccine has significant effect on killing breast cancer.
