Proteins must match up correctly to catch a ride from one site to another in the cell

Budding wing from irradiated fruit fly larvae, magnified about 80 times; various aspects of apoptosis in a regular fly (left column) are compared with the mutant fly lacking the drice gene (right column). Upper row: “reporter” proteins are highlighted with green fluorescent protein; middle row: the cutting up of these reporter proteins by caspases; bottom row: numerous cells die by apoptosis in the regular fruit fly (left), whereas almost no apoptosis occurs in the fly lacking the Drice caspase (right)

What separates the cells that are prone to suicide from those that are long lived?

Mouse hippocampus containing two different types of channelrhodopsins. The green fluorescence marks axons entering into the hippocampal CA1 region, and the red fluorescence is expressed in the dentate gyrus part of the hippocampus (inverted V-shaped structure)
