A team of researchers led by The Hospital for Sick Children, the University of Toronto and Cold Spring Harbor Laboratory have discovered a protein that is responsible for shaping the nervous system.
This research is reported in the journal Neuron.
" We discovered that p63 is the major death-promoting protein for nerve cells during fetal and post-natal development," said David Kaplan, the paper's senior author, at The Hospital for Sick Children and at University of Toronto." Proteins such as p63 that regulate beneficial cell death processes during development may cause adverse affects later in life by making us more sensitive to injury and disease."

The body disposes of the excess cells by...
