Presentation of viral epitopes to CD8 T cells by LCMV-infected MΦ. (A) Polarized Sp-MΦ were infected with LCMV-WE (MOI 5) before testing for expression of LCMV-NP 24 h later. (B) In parallel, the same infected Sp-MΦ or uninfected negative controls were tested for their ability to directly present the LCMV GP33-41 or NP396-404 epitopes to their specific CTL cultures by assaying for IFN-γ production after in vitro stimulation by ICS. (C) Graphical representation of dot plots from B showing mean ± SD from three repeats. CTL, cytotoxic T lymphocyte; LCMV, lymphocytic choriomeningitis virus infection.
