The essential components of the immune system that control primary and chronic infection with herpes simplex virus type 1 (HSV-1) in mice were investigated. Infection within the first few days can be controlled by alpha/beta interferon (IFN-alpha/beta) alone without significant contribution of B, T, or NK cells. IFN-alpha/beta and IFN-gamma cooperate in the elimination of virus in the absence o...
BACKGROUND Ongoing Helicobacter pylori (HP) infection triggers a chronic active gastritis. Eradicating HP reduces gastric inflammation, but does not eliminate it. We sought to characterize this persistent gastritis, and demonstrate the persistence of HP-specific Th17 responses in individuals previously infected with HP but who no longer had evidence of ongoing infection. METHODOLOGY/PRINCIPAL...
A 15-year-old boy with a 13-year history of periodic fevers, lymphadenopathy, and leukocytosis showed virological, serological, immunohistologic, and molecular evidence of persistent, active, Epstein-Barr virus (EBV) infection. Acyclovir and several other agents failed to alter his clinical course. Comprehensive immunological studies could not identify a defined immune deficiency syndrome to ex...
