Dr. Wang's Laboratory

Hanjun Wang, MD, aims to develop novel neuro-modulation therapies to treat cardiopulmonary diseases and chronic pain.

The laboratory has a long track record in exploring the role of skeletal muscle afferents in mediating cardiopulmonary dysfunction and exercise intolerance during physical activity in chronic heart failure.

In collaboration with Iraklis Pipinos, MD, in the UNMC Department of Surgery, Dr. Wang is exploring a new role of skeletal muscle afferents in mediating “claudication” in peripheral arterial disease (PAD). Most importantly, our jointed teams are developing a novel therapeutic concept to treat “claudication” by selective ablation of skeletal muscle afferents with an ultrapotent neurotoxin, resiniferatoxin. 

 

Lab Techniques 

  • In Vivo Electrophysiological Recordings - We are very good at recording both sympathetic and parasympathetic afferents and efferents activity in rodents and large animals in real time (PMCID: 3036195, 3378347 and 4162756). 
  • Brain and Spinal cord Research - Our lab is also good at the experiments of central microinjection/single neuron recording in any brain nucleus site in rodents (PMCID: 27151332, 3727025 and 4346766).
  • Pain behavior Assessment - Our lab is routinely performing many kinds of pain behavior assays including Von Frey, Hot plate, Incapacitance Test etc.
  • Pressure-Volume (PV) Loop Analysis - Our lab is one of very few labs in campus who is capable to perform PV loop analysis, a gold standard technique to assess cardiac function, in rodents. (PMCID: 24980663 and 5390865 )
  • Patch Clamp - Our lab uses patch clamp to explore the cellular mechanisms underlying cardiopulmonary and skeletal muscle afferent dysfunction in diseases (PMID: 30909643).
  • Tissue Clarity - The process of clearing tissue for the purpose of histological analysis has recently become a common tool in biological investigations. The purpose is to keep the proteins in a structure while removing the lightscattering lipids, and thus to allow deep penetration of light for fluorescent 3D microscopy. Our lab focuses on the advancement in the procedure called CLARITY (Clear Lipid-Exchanged Acrylamidehybridized Rigid Imaging/Immunostaining/In situ-hybridization-compatible Tissue-hYdrogel) in peripheral nervous system. It is a convenient histological fixation and clearing technique that enables immunohistochemistry and maintenance of fluorophores during imaging of large volumes for 3D-reconstruction.
