Each mother fashioned fishing tools from sticks, palm fronds or grass and inserted the first several inches into tunnels in...Two molecules work together to aid transport of immune cells, UT Southwestern researchers find
...ientists found that in order to get the T-cells to stick firmly to the vascular wall, the CD44 and VLA-4 receptors on the T-cell had to be physically linked. If they do not form what's called a bimolecular complex, firm adhesion does not occur. "Our findings define a relationship between CD44 and VLA-4 tha...Spiders make best ever Post-it notes
