An amazing animation of helper T-cell activation. Whatever that is. (Biology wasn’t my best subject.)
Apparently “[t]he lymphocyte crawling along the arteriole wall at the beginning has picked up a foreign signal, and has latched onto a macrophage through the T-cell receptors and major histocompatibility receptors. Then we dive into the cell, and the majority of the video shows the synthesis, sorting, and delivery of T-cell receptors, cytokines, and other proteins, and we finish with the now-alerted and activated lymphocyte slipping in-between the capillary wall cells on its way to trouble.

That was awesome. Thanks for posting it! I was just reading the NYT story about computers in the year 2016 and a microbiologist from Berkeley mentioned that computers have more and more to do with his work-- this is a great example of how computers enhance our lives (even though I often feel a slave to mine).
