Fig. 7 A shows that J cells expressing αvβ6-integrin alone or αvβ8-integrin alone, in the absence of nectin1, did not enable HSV infection, in contrast to cells expressing nectin1 alone. Thus, neither of the two integrins suffices as HSV receptor in cells negative for gD receptors. Parenthetically, in this assay, in the absence of gD receptors, the candidate gB receptor PILR α [40] did not enable infection. Here, NECTIN1 is linked to infection.
