Two daughter cells of a T-cell. The blue dye shows the nucleus; the green dye shows the CD 8 protein, an immune cell marker; the red dye shows the amount of the mTORC1 enzyme in each cell; the purple dye shows the activity of mTORC1 enzyme (one cell has high activity and the other has very faint activity)
