Vaccination of mice with B16 cells expressing the CRT-E2 fusion protein induces anti-tumor immune responses / 中国免疫学杂志

ABSTRACT

Objective:To study the anti-tumor effects by vaccination of mice with murine melanoma B16 cells expressing calreticulin (CRT) and Human papillomavirus 16 E2 fusion protein.Methods:Mice were inoculated with B16 cells expressing CRT,E2,or CRT-E2 by intraperitoneal injection. The inoculation was repeated after one week. The activity of CTLs and NK cells,the proliferation of T cells and the amount of IFN-? secreted by spleen lymphocytes were analysed.Results:The activity of CTLs and NK cells,and the amount of IFN-? secreted by spleen lmyphocytes from mice vaccinated with CRT-E2 fusion protein were significantly higher than those of the other groups(P
