Mitochondrial power grids in muscle
Researchers found that mitochondria in mouse muscles not only produce energy, but can quickly distribute it across the muscle cell through a grid-like network. The findings reveal a major mechanism for energy distribution in skeletal muscle cells, and could provide new insights into diseases linked to energy use in muscle.
What a wonderful example of how much we still have to learn about muscle tissue (and others too, I’m sure, but muscle seems to be particularly full of surprising puzzles). It seems likely that we probably can’t understand muscle pain properly if we have only just now discovered something so fundamental about muscle biology. Imagine trying to troubleshoot an electrical problem if you weren’t aware of a major feature of how power is generated and transmitted!
