Establishing a Mouse Model for Sexual Transmission and Male Reproductive Tract Persistence of Ebola Virus.

Ebola virus disease (EVD) has resulted in the death of over 15 000 people since its discovery in 1976. At least 1 incident of re-emergence of EVD has been associated with persistent male reproductive tract infection in a patient surviving EVD greater than 500 days prior. To date, animal models of Ebola virus (EBOV) infection have failed to fully characterize the pathogenesis of reproductive tract infection.

Overexpression of the astrocyte glutamate transporter GLT1 exacerbates phrenic motor neuron degeneration, diaphragm compromise, and forelimb motor dysfunction following cervical contusion spinal cord injury.

A major portion of spinal cord injury (SCI) cases affect midcervical levels, the location of the phrenic motor neuron (PhMN) pool that innervates the diaphragm. While initial trauma is uncontrollable, a valuable opportunity exists in the hours to days following SCI for preventing PhMN loss and consequent respiratory dysfunction that occurs during secondary degeneration. One of the primary causes of secondary injury is excitotoxic cell death due to dysregulation of extracellular glutamate homeostasis.
