Correlation of virus replication, cytokine (TNF-alpha and IL-1) producing cells, neuronal necrosis and inflammation after intranasal infection of mice with herpes simplex virus strains of different virulence.
The number of TNF-alpha and IL-1 beta producing cells was investigated during the acute replication phase of herpes simplex virus (HSV) in trigeminal ganglia after intranasal infection with strains of different virulence. The highly virulent strain WAL replicated strongly and induced many cytokine producing cells early in the ganglia. The low virulent strain HFEM replicated less, only few cytokine producing cells were detected late. The thymidine-kinase negative (TK-) virus 1301 did not replicate but produced some lymphocytic inflammation. The higher the virulence of strains of HSV-1 or -2 was, the stronger was the extent of histopathological lesions; moreover, a dissociation in time between replication and cellular reaction (granulocytic and lymphocytic) could be observed after infection with strains HFEM and TK- virus 1301. CD4 and CD8 positive cells could be detected mainly at the rim of necrotic areas, TNF-alpha and IL-1 beta producing cells, however, were scattered throughout the ganglia.
