The astonishing capacity of the brain to process and store information crucially relies on properly functioning synapses. They provide the connecting entities within neural circuits and their properties define circuit function. An international team from Australia, Belgium, Austria and Germany has received funding of total 1.4 million euros from the renowned Human Frontier Science Program (HFSP) for research into lipid structures in the cell membranes of synapses. Among the four participating laboratories is that of Dr. Michael R. Kreutz at the Leibniz Institute for Neurobiology (LIN) in Magdeburg.
The molecular composition of synapses can be very different. While the role of proteins, as core components of the synaptic cell membrane and synaptic transmission has been addressed in certain detail it is unclear to what extent the molecular diversity of lipids can influence synaptic function.
"We are entering new scientific territory here and it is not even said that our research approach even works methodically at all. We expect to have to develop new technologies further and that is of course a big challenge," explains Kreutz, head of the Neuroplasticity Research Group. Nevertheless, the four participating labs have a common vision that also convinced the reviewers of the Human Frontier Science Program (HFSP): "We want to find out which lipids are present in which synapses and how they interact with the proteins."
Based on new technologies that for the first time allow lipidomic studies at the level of different synapse types, the project aims to uncover the molecular interactions between lipids and proteins. "Newly developed analytical strategies as well as innovative lipid tagging and imaging approaches will allow us to determine the membrane composition of specific synapses with high resolution," says Kreutz. In their joint project, four labs have joined forces to explore the whole thing from a biochemical, chemical and molecular biology perspective over the next three years. The other three participants come from the universities in Vienna, Wollongong and Leuven.
About the Human Frontier Science Program (HFSP)
The Human Frontier Science Program (HFSP) promotes international collaboration in basic research focused on elucidating the intricate and complex mechanisms of living organisms. It is a highly competitive funding scheme. The funding rate of submitted projects is about three percent.

You can combine search terms with and, or and/or not, e.g. Philo not logy.
You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).
Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.
You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).
If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
