Identification of the cell types producing IFN-γ and MIP-1α mRNA. Lymph node sections were subsequently labelled with anti-CD4 (A, C), anti-CD8 (B, D), and anti-CD68 (E), respectively, and hybridized with an IFN-γ (A, B) or MIP-1α (C, D, E)-specific riboprobe. Double-positive cells were marked with an arrow. (Mag. A × 168, B–E × 100.)
