CD141+ DCs cross-present Ag from HCMV-infected necrotic fibroblasts. (A) Uptake of PKH-26–labeled HCMV-infected necrotic fibroblasts (nHCMV-Fb) by DC subsets after 12 h at 4 and 37°C by flow cytometry from a representative donor (left) and by three donors (right). (B) Uptake of nHCMV-Fb by confocal microscopy at 200×. Bars, 10 µm. (C) Cross-presentation of the pp6595-503 epitope after uptake of nHCMV-Fb or control uninfected Fb by CD141+ DC and CD1c+ DC subsets to a pp65-specific CD8+ T cell line, as assessed by IFN-γ secretion by the T cells. Left, one representative of four donors. Right, four donors, expressed as specific IFN-γ production (nHCMV-Fb-uninfected Fb for each cell type).
