New cell death pathway involved in sperm development

Heavy and bulky sperm would not be good swimmers. To trim down, sperm rely on cell death proteins called caspases, which facilitate the removal of unwanted cellular material and radically remodel these cells into their sleek, light shape. New research from scientists at the Howard Hughes Medical Institute and Rockefeller University has now uncovered a new pathway that regulates these killer...

The finding could lead to...
