wt-Vero cells express the simian ortholog of HER2, and indeed infection of these cells with either R-213 and R-LM113 was inhibited by prior incubation of the cells with trastuzumab, the anti-HER2 human antibody from which the scFv to HER2 was derived (Fig. 2A, panel e, and B, panel p). The gene discussed is ERBB2; the disease is infection.
