Local RNA metabolism in neurons and neurodegeneration

We are focusing on understanding the molecular mechanisms that regulate intracellular RNA localization, translation, and stability and role of RNA-binding proteins and non-coding RNAs in this process.

Only long-living RNAs reach their destination

RNA molecules travel long distances through nerve cells. To reach their destination, they need one thing more than any other – a long life – as a research team led by Marina Chekulaeva from MDC-BIMSB reports in the journal “Molecular Cell.”

Decoding cellular zipcodes

Researchers suspect that neurodegenerative diseases occur when messenger RNA (mRNA) goes astray in the neuron. With a new method, Marina Chekulaeva is able to identify “zipcodes” that assign a destination to mRNAs. She has now presented her method in the journal Nature Neuroscience.

How SARS-CoV-2 takes over the cell's protein factory

The question of how the Covid virus takes over host cells and suppresses the body's defences has been the subject of much debate. Now a research team led by Marina Chekulaeva at the MDC has pinpointed the crucial mechanism involved. Their results have been published in the journal “RNA”.

Downtime at the nerve cell’s protein factories

A team led by MDC researcher Marina Chekulaeva has figured out why protein production slows down in the nerve cells of people suffering from Charcot-Marie-Tooth disease. This discovery could lead to a new therapeutic approach, the scientists report in the journal "Nucleic Acids Research".

The logistics of neuronal messenger RNAs

Where proteins are localized within a cell is crucial to their proper function, especially in cells like neurons. It affects neuronal development and even learning and memory. A research team led by Marina Chekulaeva has for the first time systematically analyzed how this localization comes about. Their article appeared in Nature Communications.

New study shows circular RNA can encode for proteins

A group of scientists in Israel and Germany, led by Prof. Sebastian Kadener from the Hebrew University of Jerusalem, have discovered a protein-encoding function for circular RNA. This kind of RNA molecule is highly active in brain cells and could play an important role in neurodegenerative diseases.
