ABSTRACT
Seizure disorders are often associated with infectious etiologies. Infection, via the intracerebral (i.c.) route, of C57BL/6J mice with the Daniels (DA) strain of Theiler's murine encephalomyelitis virus (TMEV) results in approximately 50% of the mice developing acute behavioral seizures. TMEV-DA is the wild-type strain of the virus that replicates within the parenchyma of the brain. A variant of TMEV-DA, TMEV-H101, does not replicate within the parenchyma of the brain. However, infection with TMEV-H101 via the i.c. route still results in approximately 40% of the mice developing acute behavioral seizures. Infiltrating macrophages producing interleukin-6 (IL-6) have been implicated in the induction of acute seizures following TMEV-DA infection. We examined macrophage infiltration and microglial activation within the brain and cytokine levels in the periphery in mice infected with TMEV-DA or TMEV-H101 and assessed the effects of the addition of recombinant IL-6 to the periphery in wild-type and IL-6 knockout mice infected with TMEV-DA. We found that pathologic levels of IL-6 in the periphery may play a role in the development of seizures when viral replication within the brain is limited. Examination of the role played by the peripheral immune system in the development of seizures/epilepsy in the TMEV-induced seizure model, the first viral infection driven model for epilepsy, could lead to the elucidation of novel therapeutics.
