โฆ Synopsis
The distribution of virus and the composition of the mononuclear inflammatory response were studied in the brains of 7 children who died with Japanese encephalitis. Viral antigen was localized to neurons, with greatest involvement in the thalamus and brainstem. Quantitation of perivascular inflammatory responses showed a preponderance of T cells, but only 7 to 30% of these cells were T suppressorkytotoxic cells. Inflammatory cells invading the parenchyma were predominantly macrophages with small numbers of T cells. B cells remained localized to perivascular cuffs. Viral antigen was progressively cleared in patients with survival of 6 days or more.
