CSF2 and epilepsy: Most of the brain tissue examined did not exhibit detectable GM-CSF (see Table 3﻿ note 4, Additional file 2: Figure S2H); however, GM-CSF was present in the hippocampus (15/48 epilepsy and 0/3 nonepileptic cases), entorhinal cortex (3/58 epilepsy and 1/4 nonepileptic cases), and temporal cortex (22/55 epilepsy and 3/4 nonepileptic cases).
