While P2Y1 was detectable at low levels in cortical neurons and microglia under control conditions and following status epilepticus (Figures 2A, B), no co-localization was observed using the astrocyte markers GFAP and S100β in vehicle-injected control mice and in mice subjected to status epilepticus (Figures 2C, D). The gene discussed is S100B; the disease is status epilepticus.
