A team of researchers from Germany has developed an AI tool called MemBrain v2 that can map 3D cell membranes quickly and accurately. This tool can help scientists study how cells work and what happens when disease develops.
Cell membranes are like the outer walls of a house, controlling what goes in and out of the cell. But studying them in 3D images of cells has been a slow process until now. A team from Helmholtz Munich, the Technical University of Munich (TUM), and the Biozentrum of the University of Basel has developed MemBrain v2, an AI tool that automates this task.
The study is published in Nature Methods and the freely available software can find membranes, locate specific membrane proteins, and analyze how they are arranged. This helps scientists understand how cellular processes work at a molecular level. The AI requires little or no additional training data to do this, making it easy for researchers around the world to use.
Cryo-electron tomography (cryo-ET) is a special microscopy technique that lets researchers look inside cells in three dimensions and at very high resolution. But analyzing membranes in cryo-ET images has been difficult due to technical limitations of the imaging process. MemBrain v2 solves this problem by automating the process.
The tool combines three steps in one: finding membranes, locating proteins, and measuring how these proteins are arranged. In several applications, it matched manual results but was much faster. It's also easy to use and can be applied to other research questions without major adjustments.
Because all components are open source, the membrane-detection module is already widely used around the world. The tool has contributed to new biological insights, including a study that showed how important proteins work in cells.
