Membrane Systems Biology

Senior Scientist: Kenji Maeda

Human cells combine thousands of different lipids to construct the diverse cellular membranes with each their properties and functionalities.

We investigate architecture of human cells, and how it is altered in cancers with focus on these membrane lipids. To achieve this, we combine mass spectrometry-based lipidomics and in-house developed methods of systematic purification of diverse cellular compartments.

Our goal is to identify key regulatory mechanisms in the metabolism and transport of lipids essential for cancer pathophysiology and to exploit them in therapeutic strategies.
