Reshaping the brain: direct lineage conversion in the nervous system

During embryonic development, cells in an uncommitted pluripotent state undergo progressive epigenetic changes that lock them into a final restrictive differentiated state. However, recent advances have shown that not only is it possible for a fully differentiated cell to revert back to a pluripotent state, a process called nuclear reprogramming, but also that differentiated cells can be direct...

Direct somatic lineage conversion.

The predominant view of embryonic development and cell differentiation has been that rigid and even irreversible epigenetic marks are laid down along the path of cell specialization ensuring the proper silencing of unrelated lineage programmes. This model made the prediction that specialized cell types are stable and cannot be redirected into other lineages. Accordingly, early attempts to chang...

ADENOSINE IN THE CENTRAL NERVOUS SYSTEM

Besides being a metabolite of nucleotides like ATP, adenosine is a mediator of neuronal function in the central nervous system. Its actions are mediated by at least three extracellular receptors. In this review different aspects of adenosine such as biosynthesis, release, inactivation and its receptors are discussed. It also covers pre- and postsynaptic effects as well as postreceptor mecha...
