Yale researchers demonstrate the crucial role of a membrane lipid called phosphatidylinositol-4,5-bisphosphate (PtdIns (4,5)P2) in the communication of information between synapses in the brain, according to a study published this week in Nature.
"This study is the first to show that lowering the levels of this lipid in nerve terminals affects the efficiency of neurotransmission," said senior author, Pietro De Camilli, Eugene Higgins Professor of Cell Biology and a Howard Hughes Medical Institute investigator.
De Camillis laboratory has extensively studied the mechanism underlying cycling of synaptic vesicles, the small sacs containing neurotransmitters that exchange information between neurons. Synaptic vesicles release their contents at junctions between nerve terminals by fusing with the plasma membrane where they rapidly re-internalize, reload with neurotransmitter, and are reused.

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
