Research and Practice Interests

Although animal models have greatly increased our understanding of the mechanisms involved in the disease process, the translation of this information to the human condition has had a high failure rate including the translation of animal data to human neurological diseases. Pain, in particular, has been highly disappointing since there are very few examples of analgesic drugs that have translated from animal studies alone. These outcomes suggest that the animal models currently in use need to be improved or that there are key differences between humans and animal models. Possible differences at the cellular level are the signal transduction pathways activated, the posttranslational modifications that result, and/or the alterations in gene transcription or translation. In order to address the differences in the molecular mechanisms, ex vivo human neural tissue is needed.  Human nervous tissue is rarely obtained, is present in limited quantities, and if diseased it is obtained at late stages of the disease. Another source of human neurons and non-neuronal brain cells (i.e., various glia cell types) is human embryonic stem cells (hES cells).  Most research on hES cells has focused on regeneration and development, yet the neurons obtained are both electrically active, end terminally differentiated, and have been shown to mature under in vitro conditions. This laboratory is testing the hypothesis that human central neurons differentiated in vitro from hES cells are a functionally and genetically representative model for human neurons and display cellular level differences from rodent animal models.
