In 129 mice, infection with the nairovirus Dugbe virus (DUGV) was lethal following intracerebral but not intraperitoneal inoculation. Following both routes of inoculation, immunostaining of tissue sections demonstrated virus-positive cells in the brain, indicating that DUGV is neuroinvasive in mice. Many brain areas were affected and neurones were the main cell type infected. Infected cells showed punctate accumulations of viral nucleoprotein in the cytoplasm, indicative of virus replication sites. Immunostaining for activated caspase 3 demonstrated no evidence of apoptosis. The type I interferon (IFN) system plays a significant role in defence against DUGV, as 129 IFN-alpha/beta R-/- mice died rapidly following both intraperitoneal and intracerebral inoculations. Studies were undertaken to determine whether the IFN-inducible proteins, protein kinase R (PKR) and MxA, were important for protection; neither PKR nor constitutively expressed human MxA played significant roles.
