Researchers have developed a new technology called Ribo-STAMP that can directly measure protein production in individual brain cells. Using this method, they created the first detailed maps of protein translation across nearly 20,000 cells in the mouse hippocampus, a brain region essential for learning and memory. The findings reveal unexpected differences in protein production between similar neuron types and suggest a link between mRNA isoforms and protein levels that could be relevant for neurological disorders.

Why it matters

Understanding how healthy brain cells coordinate protein production is crucial for unraveling the underlying causes of neurological conditions like autism spectrum disorder, fragile X syndrome, and tuberous sclerosis complex, which may involve defects in translation. This new technology provides a powerful tool to investigate these links and could lead to better treatments.

The details

The Ribo-STAMP method works by fusing a molecular editing enzyme to ribosomes, the cellular machines that carry out protein translation. As ribosomes translate mRNA into proteins, the enzyme makes changes to the RNA strand, allowing researchers to identify which RNAs were translated using standard sequencing. When applied to the mouse hippocampus, the researchers found surprising differences in translation rates between similar neuron types, as well as links between specific mRNA isoforms and higher protein production.
