Description of research:
In our laboratory we are studying cerebrovascular diseases of and trauma to the central nervous system (CNS), such as stroke and spinal cord injury (SCI), to try to understand the cellular and molecular mechanisms that contribute to inflammation and secondary neuronal cell death. We have primarily one main research objective, which is to study the neuro-inflammatory response that occurs following stroke and SCI with the aim to contribute to the development of novel therapies for stroke and SCI patients.

To determine what role inflammation plays following CNS injury we use transgenic mouse models and other molecular approaches to study the central but complex role of the pleiotrophic cytokine tumor necrosis factor (TNF) for neuronal survival/death. We specifically use conventional and conditional knock out models in which TNF and/or its receptors can be manipulated in all cells or in tissue specific cells, including microglia, leukocytes, oligodendrocytes and neurons. We also use a variety of anti-TNF drugs targeting both the transmembrane and the soluble forms of TNF in order to elucidate the very complex role of this signaling molecule in modulating neuroinflammation following CNS injury.

We hope to be be able to contribute to identifying novel neuroprotective therapeutics for treatment in stroke and SCI.
