Local RNA metabolism in neurons and neurodegeneration

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”.

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".

Under a new grant from the EU, Marina Chekuleava of the MDC will lead a multinational consortium to find common mechanisms in diverse motor neuron diseases

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.

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.
