The antibodies used in this study are listed in Supplemental Table 1. The following cell lines were used: HaCaT keratinocytes (Addex Bio) and THP-1 (American Type Culture Collection [ATCC], TIB-202). The recombinant HSV-2 strain 333, which encodes the β-gal bene (HSV-2/Gal) under CMV promoter control, inserted between virus UL3 and UL4 genes, was provided by Patricia Spear and Richard Longnecker (Northwestern University, Evanston, Illinois, USA) (31 (link)). The stem of influenza hemagglutinin (Flu-HA) strain H1 1999 NC was expressed using the vector VRC-3925 (32 (link)) in 293F cells and was provided by M. Gray and L. Stamatatos (Fred Hutchinson Cancer Research Center, Seattle, Washington, USA). The HSV-2 proteins gB2, gC2, and gH2/gL2 were provided by G. Cohen and R. Eisenberg (University of Pennsylvania, Philadelphia, Pennsylvania, USA). The HSV-2 proteins UL19ud, UL25, and gD2 (33 (link)) were provided by Immune Design Corp.
