Making daughters different -- how immune cells take divergent paths when fighting infections

... immune cell reacting to a microbe must become the soldiers that fight the infection and die; but some, instead, regenerate to take the place of the mother cell, leaving an immunologic memory to recognize the invading microbe in the future. Given the simplicity of this scenario, surprisingly few examples ha...
