Background

Radiotherapy (including diagnostics) in combination with chemo-/immunotherapy or other neurotoxins causes severe side effects such as cognitive impairment. The underlying mechanisms are poorly understood but are associated with impaired neurogenesis/regeneration.

Objective

Based on human embryonic stem cells, a test to mimic human neurogenesis/regeneration will be performed by generating brain-like organoids/cultures containing the major cell types of the brain such as neurons, glial cells and microglia/macrophages. Clinically relevant combinations of radiation (X-ray and carbon ions) and chemo- or immunotherapy, as well as other neurotoxins (e.g. anticonvulsants), are tested to identify the signalling pathways and their regulators that are altered and lead to impaired neuronal function.

  • Method

    The functionality of brain-like organoids/cultures is analysed using microelectrode arrays after exposure to ionising radiation and chemotherapeutic agents.
