Research Overview
The Rieger Lab studies wound healing mechanisms using zebrafish as a model. Wound healing is an intricate process that requires coordinated interactions between various cell types. The small reactive oxygen species hydrogen peroxide is a key signaling molecule that has been found to stimulate various wound repair processes, including immune and epidermal cell migration and the regeneration of sensory nerve endings. Our lab is particularly interested in the signaling functions of hydrogen peroxide leading to the crosstalk between nerve endings and epidermal cells, as these interactions are required for wound healing.
We are further interested in the development of therapeutic strategies that promote sensory nerve regeneration and wound healing in chemotherapy patients. Many chemotherapy patients suffer from decreased wound healing following surgical intervention. About 30-40 percent also develop peripheral neuropathy, a condition of nerve degeneration. The underlying causes for each of these conditions are unknown. We have established a zebrafish model to study the effects of one chemotherapeutic agent, paclitaxel, on wound healing and nerve degeneration. This research has led to the identification of two compounds that promote wound and nerve repair in zebrafish. Both compounds are under investigation for their effects in mammals
