Use of a Wireless Video-EEG System to Monitor Epileptiform Discharges Following Lateral Fluid-Percussion Induced Traumatic Brain Injury.

The lateral fluid percussion injury (FPI) model is well established and has been used to study TBI and post-traumatic epilepsy (PTE). However, considerable variability has been reported for the specific parameters used in different studies that have employed this model, making it difficult to harmonize and interpret the results between laboratories. For example, variability has been reported regarding the size and location of the craniectomy, how the Luer lock hub is placed relative to the craniectomy, the atmospheric pressure applied to the dura and the duration of the pressure pulse.

Dimethyl fumarate ameliorates myoclonus stemming from protein misfolding in oligodendrocytes.

Multiple sclerosis (MS) is considered a primary autoimmune disease; however, this view is increasingly being challenged in basic and clinical science arenas because of the growing body of clinical trials' data showing that exclusion of immune cells from the CNS only modestly slows disease progression to disability. Accordingly, there is significant need for expanding the scope of potential disease mechanisms to understand the etiology of MS. Concomitantly, the use of a broader range of pre-clinical animal models for characterizing existing efficacious clinical treatments may elucidate additional or unexpected mechanisms of action for these drugs that augment insight into MS etiology.

A novel full-length isoform of murine pregnancy-specific glycoprotein 16 (psg16) is expressed in the brain but does not mediate murine coronavirus (MHV) entry.

The mouse pregnancy-specific glycoprotein 16 (PSG16) has been reported to be an alternative receptor for mouse hepatitis virus (MHV), some strains of which cause encephalitis in mice lacking the canonical receptor CEACAM1a. The known isoforms of PSG16 are N-terminally truncated relative to other PSG family proteins and are expressed in neurons as well as in the placenta. We have cloned a novel full-length isoform of psg16 that is also expressed in the brain, placenta, and retina but, like the truncated form, lacks MHV receptor activity when expressed on 293T cells, suggesting that PSG16 does not mediate CEACAM1a-independent spread of MHV.
