The model can be therapeutically exploited to identify IDH wild-type GBM with good prognosis who will most likely benefit from neoantigen based personalized immunetherapy. Furthermore, the prognostic intrinsic features of the neoantigens inferred from this study can be used for identifying neoantigens with high potentials of immunogenicity. Rodent brain slices-particularly hippocampal slices-are widely used in experimental investigations of epileptiform activity. Oxygenated artificial cerebrospinal fluid (ACSF) is used to maintain slices in vitro. Physiological or standard ACSF containing 3-3.5mMK , 1-2mM Mg , and 1-3mM Ca generally does not induce population epileptiform activity, which can be induced by ACSF with high K (8-10mM), low Mg , or low Ca alone or in combination. While low-Mg ACSF without intentionally added Mg salt but with contaminating Mg (≤ 50-80µM) from other salts can induce robust epileptiform activity in slices, it is unclear whether such epileptiform activity can be achieved using ACSF with moderately decreased Mg . To explore this issue, we examined the effects of moderately modified (m)ACSF with 0.8mM Mg , 1.3mM Ca , and 5.7mMK on induction of epileptiform discharges in mouse hippocampal slices. Hippocampal slices were prepared from young (21-28days old), middle-aged (13-14months old), and aged (24-26months old) C57/BL6 mice. Conventional thin (0.4mm) and thick (0.6mm) slices were obtained using a vibratome and pretreated with mACSF at 35-36°C for 1h prior to recordings. During perfusion with mACSF at 35-36°C, spontaneous or self-sustained epileptiform field potentials following high-frequency stimulation were frequently recorded in slices pretreated with mACSF but not in those without the pretreatment. Seizure-like ictal discharges were
