Mitochondria from Different Brain Cells Have Different Proteins

Recommendable! Are humans finally learning the complexity of life?

"Comparing protein levels in these three cerebellar cell types—excitatory neurons called granule cells, inhibitory neurons called Purkinje cells, and nonneuronal cells called astrocytes—Misgeld’s team looked for notable variation. Among these few cell types, “that already gives you variability in about 10 percent of the proteins that people believe make up a mitochondrion,” says Misgeld. ...”"

Mitochondria from Different Brain Cells Have Different Proteins | The Scientist Magazine® Organelles isolated from two types of neurons and a nonneuronal astrocyte in the mouse cerebellum showed varying levels of proteins, hinting at functional differences.
