Pancreatic Neuropathy & Pain · TUM University Hospital · Munich

Where pancreatic disease meets the nervous system.

We investigate how nerves, cancer cells, stromal and immune cells communicate in pancreatic cancer and pancreatitis — from neural invasion and neuropathic pain to neuron–cancer synapses and therapeutic translation.

Our mission

Decoding the neural biology of pancreatic disease.

Our group combines pancreatic surgery, cancer biology, neuroscience and translational medicine to understand how the nervous system shapes disease progression, treatment resistance and pain — and to turn these mechanisms into therapeutic opportunities.

SYNAPSE-ON-CANCER

Deciphering and Targeting the Synapses between Cancer Cells and Neurons in Pancreatic Cancer

Pancreatic cancer cells receive signals from neurons — not diffusely, but through synapse-like contacts. SYNAPSE-ON-CANCER maps these connections, measures their electrical and molecular activity, and tests whether blocking them slows tumour growth. Funded by the European Research Council with a Consolidator Grant (€2 million, 2025).

Else Kröner Clinician Scientist Professorship

Translational Pancreatic Surgery

Endowed professorship at the Department of Surgery, TUM University Hospital — awarded to Prof. Dr. Dr. Ihsan Ekin Demir in 2020

The professorship funds our work on neural invasion in pancreatic cancer. It has allowed us to identify molecular pathways that let tumours grow along nerves — and to pursue the goal behind them: a drug that blocks the interaction between tumour and nerve cells, and with it improves prognosis. The Else Kröner-Fresenius-Stiftung created this funding line to give clinician scientists protected time for research alongside clinical work.

Paper of the Month · February 2026

The foundation selected our Cancer Cell paper on glutamatergic neuron–cancer pseudo-synapses as its Paper of the Month. Read more

Translation

From the operating room to the mechanism — and back.

Our identity is the bridge between clinical pancreatic surgery and mechanistic neuroscience.

  1. Patient
  2. Surgery
  3. Human tissue
  4. Experimental model
  5. Mechanism
  6. Therapeutic concept
We take our questions directly from human tissue — and return the answers to where they came from.
