Friedrich Götz’s project aims to elucidate the role of bacteria-derived neurotransmitters in the development and progression of diabetic foot ulcers (DFU) and DFU-associated peripheral neuropathy (DPN).

A diabetic foot ulcer (DFU) is a poorly healing open wound that occurs in about 15% of patients with diabetes. Of those who develop DFU, 6% will be hospitalized due to infection or other ulcer-related complications. Previously, Friedrich Götz and his team have found evidence that neurotransmitter-producing bacteria of the skin (here termed neuromicrobiota) may have an impact on the healing process. However, it remains unknown whether the effects are beneficial or detrimental to wound healing.

In Friedrich Götz’s project it is hypothesized that permanent stimulation of neuronal skin receptors is more detrimental for wound healing. Through a close collaboration with the Trauma Surgery at the University Tübingen, BG Clinic Tübingen which treats ~200 DFU patients/year, samples will be analyzed for a variety of parameters, including neurotransmitter content, microbiome and metagenome composition, and impact of neurochemicals on wound healing. These will be compared to samples from healthy subjects taken at similar sites.

The goal of the project is to elucidate the role of bacteria-derived neurotransmitters in the development and progression of DFU and DFU-associated peripheral neuropathy (DPN). Friedrich Götz’s project will substantially aid the scientific understanding of DFUs and may provide potential for clinical application. If bacterial-derived neurotransmitters are found to have an impact on wound healing and progression of DFU, then this may open a new avenue for therapeutic approaches to treat DFU.
