Biology is full of complex, yet efficient, systems. Signaling pathways, for example, have multiple components that often need to be specifically arranged in order to function. As evolution favors efficiency, cells have often adopted components of an already established signaling pathway for a new purpose rather than creating new pathways from scratch. Researchers from Madrid … Continue reading The Surprising Similarities between Cilia and Immune Synapse Signaling
Thousands of skilled assassins are currently moving through your body.
