Séminaire impromptu - Sighild Lemarchant"ADAMTS4 in CNS pathologies"

Abstract :

Department of Neurobiology, A. I. Virtanen Institute for Molecular Sciences,Biocenter Kuopio, University of Eastern Finland, P.O. Box 1627, 70211 Kuopio,Finland

 My research interests focus on the functions and effects of a singular multifaceted metalloproteinase, ADAMTS-4,
during CNS pathologies. I have pioneered in unraveling ADAMTS-4 contributions to mechanisms mediating neuroplasticity, neuroinflammation or neurodegeneration during 3 devastating pathologies: spinal cord injury, ischemic stroke and amyotrophic lateral sclerosis respectively.
