I am very fond of food and eat just about everything. Maybe that’s why I’m so fascinated by the immune system’s big eaters?
One of my greatest reading experiences as a young student is the chapter on biological membranes in Stryer’s Biochemistry. The text was about how the cell perimeter is built up. The solution is as ingenious as simple: Soap! I was so thrilled that I gave away a copy of the book to a friend. Stryer was almost as exciting as a mystery novel! But what does this have to do with the immune system?
Our bodies continuously encounter microbes that pose potential or actual threats to our survival. Our immune system has to be able to detect all possible threats to our bodies, whatever shape or form they may take. So how does the immune system recognize a threat? Continue reading

If not, what protected some people but not others? The doctors compared the 4th generation immigrants in Suriname and Dutch blood donors.
It’s rare for an entirely new disease to appear and garner worldwide attention, inflict severe social consequences, and simultaneously shed light on important biological principles.
