Monocyte/Macrophage (THP-1;CD68±/CD14± PBMC) - FcγRII required (intracellular domain); ADE infection achieved, but abortive in the longer term; IFN-α/β, MCP-1, IP-10, TNF, MIP-1 mRNA expression not altered post-ADE (1–72 h p.i.) This evidence concerns the gene TNF and acute disseminated encephalomyelitis.
