Document Summary
Some chemicals attract and some repel the frowning axons and dendrites. Chemoattractants, chemical released that causes the growth cone to come towards the cell/ and chemorepellants (slit) produced at the mid-line so no developing neurons can cross the mid-line. Many pro-death and pro-life genes have been identified. Inhibits diablo so iaps continue to do their job so the cell is protected from the caspsase"s. Causes changes in the cell that allow lots of calcium to rush into the cell/release calcium stores so lots of calcium flooding/initiates protein cascades. Diablo is released from the mitochondria and inhibits iaps (inhibitors of apoptosis proteins). Caspase"s eat the dna and the proteins in the cell, they are normally inhibited by iap but when diablo is released we disable iaps allowing caspsase"s to carry out destroying the cell. Neurotrophic factors are chemicals that are important for neuronal and synapse survival. Those that don"t receive neurotrophic factors will die out.
