Neonatalogie


Our research group in Regensburg on newborn infant medicine covers the first 
1000 days of life. This is the time from conception until a child’s second birthday 
and is the basis for the entire lifespan. In fact, nutrition and nurture during the first 
1000 days determine largely how the genetic makeup can be facilitated to health, 
resilience and success in whole life. In our research group on fetal and neonatal stress 
response we focus on the developing brain and the circulatory system and strive to 
improve neurodevelopment especially when damage to the brain complicated the start 
to life. The complex interaction between perception and cognition in early life presents 
an important starting point for various interventions involving care givers and in 
particular parents to improve long term outcome.

Main research projects of our research group

Blood biomarkers for monitoring brain integrity. 

Neuro-axonal damage is the pathological substrate of permanent disability in various neurological disorders. Neurofilament light chain (NfL), a neuron specific scaffolding protein, can be quantified in serum and cerebrospinal fluid, and has been proposed as a biomarker for brain injury. We test NfL usability in various neurological diseases of neonates and older children.

Multimodal monitoring of circulatory system activity in the neonatal period. We apply new monitoring devices and biomarkers to observe changes in preterm infants e.g. evolution of patent ductus arteriosus and to test novel mathematical algorithms for early prediction e.g. of infections. Dr. H. Michel is leading this research project.

Stem cell research program on neuroprotection: 

Investigating the beneficial action of therapeutic hypothermia (TH) for hypoxic-ischemic encephalopathy (HIE) in neonates to identify molecular mechanisms which can be used clinically in HIE and other diseases of severe brain damage in children and adults, e.g. in stroke. The RNA-binding motif protein 3 (RBM3) is an important mediator of neuroprotection afforded by TH and is inactivated in patients suffering from neurodegeneration. Thus, RBM3 is a promising candidate for disease monitoring and drug development.
