#1 Gene for autoimmunity Rare genetic variants in the protein sialic acid acetylesterase (SASE) are linked to common human autoimmune diseases, including type 1 diabetes, arthritis, and Crohn's disease. In mice, defects in the protein have been linked to problems in B-cell signaling and the development of auto-antibodies. I.

#2 Cell mobility illuminated Using light to activate a the protein Rac in a single cell, researchers show how the protein can induce a group of epithelial cells to polarize en masse, suggesting that these cells can sense movement as a group.
