MV-Ed infects F4/80⁺ macrophages in spleen and lung. (A to C) Sections of the spleen 3 days after i.p. infection. (A) Low magnification showing MV N RNA-positive cells in the red pulp (rp). (B and C) Consecutive sections showing colocalization of MV N RNA (B) with the MM marker F4/80 (C) in syncytia. (D and E) Consecutive lung sections 6 days after i.p. infection showing MV-specific RNA signals (D) colocalizing with F4/80-positive cells (E). wp, white pulp (darker area). Magnifications, ×87.5 (A) and ×875 (B to E).
