Damaged CNS axons are prevented from regenerating by an environment containing many inhibitory factors. They also lack an integrin that interacts with tenascin-C, the main extracellular matrix glycoprotein of the CNS, which is upregulated after injury. The alpha9beta1 integrin heterodimer is a receptor for the nonalternatively spliced region of tenascin-C,(More)
Tenascin-C (Tnc) is a multimodular extracellular matrix glycoprotein that is markedly upregulated in CNS injuries where it is primarily secreted by reactive astrocytes. Different Tnc isoforms can be generated by the insertion of variable combinations of one to seven (in rats) alternatively spliced distinct fibronectin type III (FnIII) domains to the(More)
The development of multi-cellular organisms is regulated by the ordered definition of gene expression programmes that govern cell proliferation and differentiation. Although differential gene activity is mainly controlled by transcription factors, it is also dependent upon the underlying chromatin structure, which can stabilize transcriptional "on" or "off"(More)
Sequential cleavage of amyloid precursor protein (APP) by β- and γ-secretases and the formation of Aβ peptides are pivotal for Alzheimer's disease. Therefore, a large number of drugs has been developed targeting APP metabolism. However, many pharmacological compounds have been identified in vitro in immortalized APP overexpressing cell lines rather than in(More)
