Abstract
HER-2/neu was widely used as a target for tumor prevention and therapy because of its overexpression in many tumors. However, it also plays an important role in proliferation of endometrium, embryo implantation, and development. Here, HER-2/neu was used in immunocontraception. A gene vaccine encoding the extracellular domain of human HER-2/neu was constructed. After immunization, it especially elicited both humoral and cellular responses in mice. Embryo implantation was interfered by intravenous and intraluminal injection of anti-HER-2/neu serum or lymphocytes. Lower fertility was induced after vaccination when compared with the control groups, while injuries to the uterus and ovary were not observed. Our results suggested a new and impactful target for contraceptive vaccines development.
