Research Interests

We are interested in the mechanisms and stimulation of axonal regeneration or repair in traumatic injury and neuroinflammation. We are studying the effects of IL-4 on chronic experimental autoimmune encephalomyelitis, the mouse model of multiple sclerosis. We identified a fast and direct signalling pathway of the IL-4 receptor in neurons, and in vivo protection against axonal swelling, leading to improved functional recovery. Currently, we are working on the translation of this work to the clinic. We also investigate very early axonal responses to injury by studying the translation machinery in axons. In the context of local translation, we study the axonal localization of ribosomes in response to injury. We have generated conditional transgenic mice with fluorescently labelled ribosomes in order to study the origin of axonal ribosomes. Furthermore, we are interested in the signalling mechanisms of regeneration-stimulating treatments. These studies will provide new targets to stimulate regeneration. We cover a broad range of techniques and have several local and international collaborations.

Key techniques: central and peripheral axon injury models, experimental autoimmune encephalomyelitis, lumbar intrathecal injection, nasal application, primary neuron/explant cultures, immunohisto- and cytochemistry, qPCR

Research system/organism: Mus musculus
