Tumor-associated antigen delivery via recombinant adenovirus serotype 5 vector with deleted early region genes (Ad5-TAA)

Target
Ad5-TAA
Molecular classification
Viral vector, Gene delivery system
01

Overview

Recombinant adenovirus serotype 5 (Ad5) vector with deleted early region genes (E1 and/or E3) used to deliver tumor-associated antigens (TAAs). This approach aims to stimulate an immune response against cancer cells by presenting these antigens and thereby inducing anti-tumor immunity.

Other names
rAd5-TAAReplication-defective Ad5 vector expressing TAAE1/E3 deleted Ad5 vector for cancer immunotherapy
02

Mechanism of action

The Ad5 vector infects cells and expresses tumor-associated antigens, leading to antigen presentation and activation of cytotoxic T-cells, thereby inducing anti-tumor immunity.
