Central service project in KFO 5001
Central project
In the patient-centered project Z of the research unit KFO 5001 four aims are pursued:
- Qualification of clinician scientists as future independent scientific project leaders.
- Provision of central services such as magnetic resonance neurography, collection of patient samples, and establishment of a diagnostic platform for the analysis of skin and blood samples
- Longitudinal clinical studies on the course of pain in neuropathic pain syndromes
- Generation of human induced pluripotent stem cells (hiPSCs) from skin fibroblasts to be differentiated into sensory-like neurons.
Clinician Scientist Program
How can we train research-oriented physicians in the long term and establish clinical-molecular research in Würzburg? To this end, we have come up with a concept that will be implemented in project group Z: Clinician Scientists will be trained in clinical molecular studies. Within this framework, standardized procedures for molecular diagnostics and imaging will also be established.
The Clinician Scientists are a subgroup of the Integrative Clinician Scientist College of the Interdisciplinary Center for Clinical Research (IZKF). In addition to hands-on training, participation in the PainScouts program of ResolvePAIN is provided. General research skills are acquired together with other IZKF-Clinician Scientists.

Central services
For all project participants of the KFO 5001 ResolvePAIN study, standardized new examination methods will be established in project Z. These will result from the clinical studies of patients and will be available as a central service to each project group. In addition to the collection and analysis of patient samples, these include imaging techniques.
MRI imaging of dorsal root ganglia
Both, morphological and functional changes of the dorsal root ganglia are to be investigated by imaging with high-resolution MRI special examinations during pain development and resolution. By means of contrast agent administration, we will visualize the blood flow of the dorsal root ganglion. This allows to draw conclusions about its functionality. These findings and the comparison with the dorsal root ganglion on the opposite side could provide information on the stage and prognosis of neuropathy. Within the framework of KFO 5001 and in the context of experimental new examinations, the UKW’s Department of Neurology examines the condition and changes of the dorsal root ganglia from study participants in the course of the observation period. One particular advantage is that it involves non-invasive examinations.

Biosample analysis and biosamples
In the search for biomarkers that allow assessment of the risk of pain resolution, a blood and a tissue platform will be created in the research group KFO 5001. In blood, we hope to find characteristic changes in laboratory data – also in combination or in relation to each other – reflecting the course of pain.
For tissue and skin samples, the most significant staining procedures and measurement methods are to be evaluated. This is necessary for a differentiated analysis of skin nerves, Schwann cells, receptors, growth factors or barrier molecules, which could be important in the development and regression of pain. This would allow to identify certain patterns from the results collected and therefore to develop standard diagnostic procedures.

Long-term clinical studies
Long-term clinical studies are investigating disease progression and pain regression in two conditions in which neuropathic pain is a disease-defining symptom: chronic postoperative groin pain (CPIP) and complex regional pain syndrome (CRPS). Both are characterized by improvement of pain in a larger proportion of patients, but not in some. Patients are thoroughly examined clinically and their samples are analyzed at the molecular level. Comprehensive characterization at multiple stages of disease progression in the context of systematic follow-up will also identify potential prognostic factors. Such biomarkers would enable faster intervention in the next step as well as advance personalized medicine.

Cultivation of patient-derived sensory-like neurons
We aim to generate sensory-like neurons and Schwann cells from skin fibroblasts of study participants via induced pluripotent stem cells (iPSC). Hereby, biomaterial of selected patients with neurofibromatosis or neuropathy due to a genetic predisposition will be used. By in vitro analysis of these cells in mono- and co-culture upon optimization of our protocols, we aim at understanding the underlying pathomechanisms of pain development and resolution.
