Research

Dr. Hou completed his postdoctoral training at the University of Kentucky and the University of California, San Diego (UCSD). In 2012, he joined the Spinal Cord Research Center at the Department of Neurobiology & Anatomy, Drexel University College of Medicine to continue his research into autonomic dysfunction after spinal cord injury (SCI).

Traumatic SCI results not only in sensorimotor deficits but also in autonomic dysfunction. The disruption of supraspinal autonomic pathways renders abnormalities in multiple organ systems including compromised urinary, cardiovascular, respiratory, gastrointestinal, thermoregulatory and sexual activities. Despite varied symptoms based upon the level and severity of the injury, the loss of descending regulation and subsequent maladaptation in the injured spinal cord underlie disordered autonomic activity. Over recent decades, autonomic dysfunction has drawn more investigation as researchers and clinicians begin to state their clinical priorities. Our research emphasizes both lower urinary tract and cardiovascular consequences after SCI.

The Hou Laboratory employs multidisciplinary approaches, including neuroanatomical, physiological, and cellular and molecular techniques to elucidate supraspinal and intraspinal neuronal machinery of micturition and hemodynamics in intact and SCI rat models. Recent findings revealed that spinal endogenous dopaminergic mechanisms regulate the recovered spontaneous bladder reflexes after SCI. Utilizing the cell transplantation approach, our team is further attempting to rebuild neuronal pathways for autonomic functional recovery. In the central nervous system, injured axonal projections are particularly refractory to growth due to various factors. We are exploring effective strategies to increase growth capability and reduce inhibitory aspects for axon regeneration following SCI.

Ongoing research:

  • Intraspinal neuronal mechanisms regulating spontaneous micturition reflex after SCI
  • Transplantation of neural stem cells to restore cardiovascular function following SCI
  • SCI animal models and therapeutic approaches for cardiac dysfunction
  • Combinatorial strategies for axon regeneration and target reinnervation

The Hou Laboratory uses a wide variety of techniques:

  • Surgical: spinal cord injury, cell transplantation, viral vector injection, telemeter implantation
  • Neuroanatomical: histology, immunostaining, neural tract tracing, microscopy, confocal imaging
  • Cellular and molecular: neural stem cell culture, cell reprogramming, q-PCR, western blot
  • Physiological and behavioral: bladder cystometry and external urethral sphincter (EUS) electromyography (EMG), metabolic cages, hemodynamic recordings, cardiac functional analysis, sensorimotor evaluation, DREADDs techniques

Current lab members:

  • Emily Oatman, Research Assistant II
  • Emily Taub, Research Assistant I
  • Marissa Cusimano, PhD Candidate
  • Anurag Singh, PhD Student
  • Krupa Patel, Master’s Student
  • Xiaohe Liu, Visiting PhD Student
