Improving the delivery of care for patients with brachial plexus injury: 

  • PLANeT Study – Prospective Longitudinal Assessment of Nerve Trauma. PLANeT is a multicenter prospective cohort study for patients with adult traumatic brachial plexus injury. This NIH R01 funded study is centered on selecting the most appropriate outcome measures for patients with BPI.

Dr. Brogan’s laboratory has two main lines of investigation:

Evaluating techniques to improve nerve repair and regeneration

We are interested in the role of SARM-1 in nerve repair and regeneration.  The lab has ongoing projects evaluating the inflammatory cascade after nerve injury in the absence of SARM-1 and the downstream effects on both neurogenic pain and nerve regeneration. 

Nerve Imaging

Our lab seeks to develop novel near-infrared fluorescent probes for pre-clinical and clinical use in the operating room to identify nerve injury and predict recovery.  Our current focus is to explore the role of calpain and atrogenes on development of neurogenic muscle atrophy after nerve injury as well as to better characterize the role of NAD+ in Wallerian degeneration. We accomplish this using a variety of in-vivo animal models and novel imaging techniques.

Biomarkers of Nerve Injury

We have ongoing clinical studies to evaluate the use of serum biomarkers for the diagnosis and prognosis of nerve injuries and nerve compression.  We seek to identify markers that could potentially assist with surgical planning and timing of surgery after nerve injury.
