More Information
Summary:The present invention discloses dual-targeting fusion protein CFmDEC capable of mediating a type 5 adenovirus vector to be specifically bound with a surface molecule DEC205 of a dendritic cell; and by utilizing a gene fragment sig-tG250-Fc-IRES-GM-CSF-B7.1(25) of a multi-targeted anti-renal cancer compound antigen, an anti-renal cell carcinoma adenovirus vaccine-Ad5-tG250FcGB is constructed with a type 5 replication-deficient adenovirus as a vector. The dual-targeting fusion protein CFmDEC is capable of enhancing the antitumor effect of the renal cell cancer adenovirus vaccine Ad5-tG250FcGB, is effectively combined with the adenovirus, improves the DCs-targeted ability of the adenovirus vaccine, and can induce higher specific antitumor immune response in a human body and suppress the growth of renal cell cancer.
