1. The main purposes of this study are to characterize the intracellular and extracellular responses of cells in superficial layers of entorhinal cortex (EC) in chronically epileptic animals, determine whether their altered physiology is dependent on being connected to hippocampus, and investigate whether there is evidence of augmented excitation and(More)
We investigated whether entorhinal cortex (EC) layer IV neurons are hyperexcitable in the post-selfsustaining limbic status epilepticus (post-SSLSE) animal model of temporal lobe epilepsy. We studied naive rats (n = 44), epileptic rats that had experienced SSLSE resulting in spontaneous seizures (n = 45), and electrode controls (n = 7). There were no(More)
Brain slices from adult rats that included ventral hippocampus and adjacent parahippocampal areas were studied at various sites for the appearance of epileptiform discharges as extracellular potassium ([K+]o) was systematically varied over the range of 3 mM to 10 mM. The development of evoked epileptiform discharges (EEDs) and spontaneous epileptiform(More)
The JB6 mouse epidermal cell line has been developed to study promotion of neoplastic transformation in vitro. Treatment of JB6 cells with 12-O-tetradecanoylphorbol 13-acetate (TPA) or other tumor promoters resulted in the irreversible acquisition by JB6 cells of tumorigenicity in nude mice and anchorage-independent growth in soft agar. As previously(More)
Michael John Allingham: Novel roles for ICAM1 in leukocyte transendothelial migration. (Under the direction of Keith Burridge) Leukocyte transendothelial migration (TEM) is a critical regulated step in inflammation and is therefore a potential target in the treatment of inflammatory diseases. During TEM, leukocyte-integrins bind to and cluster intracellular(More)
