abstract = {Neurons are postmitotic and thus irreplaceable cells of the
central nervous system (CNS). Accordingly, CNS inflammation
with resulting neuronal damage can have devastating
consequences. We investigated molecular mediators and
structural consequences of CD8(+) T lymphocyte (CTL) attack
on neurons in vivo. In a viral encephalitis model in mice,
disease depended on CTL-derived interferon-γ (IFN-γ) and
neuronal IFN-γ signaling. Downstream STAT1 phosphorylation
and nuclear translocation in neurons were associated with
dendrite and synapse loss (deafferentation). Analogous
molecular and structural alterations were also found in
human Rasmussen encephalitis, a CTL-mediated human
autoimmune disorder of the CNS. Importantly, therapeutic
intervention by IFN-γ blocking antibody prevented neuronal
deafferentation and clinical disease without reducing CTL
responses or CNS infiltration. These findings identify
neuronal IFN-γ signaling as a novel target for
neuroprotective interventions in CTL-mediated CNS disease.},
