"The spleen is like the maze into which the Cretan king Minos sent his prisoners. Inside the maze was a vicious creature (half-man, half-bull) who would kill the trapped prisoners. As far as the trapped red blood cell is concerned, the macrophage is like the Minotaur (and that's no bull!)."
"You informed the students that the macrophage is like the ameba except that it ingest viruses not food."
A piece of a blog about being fired, I think, from the public schools system in NYC.
"The macrophages and the neutrophils arrive. The macrophages engulf the invading organism and digest them by a process called phagocytosis. Macrophages are like scavengers, ridding the body of worn-out cells, debris and other foreign invaders. Macrophages are able to display a part of the invading organism on its surface as a signal to other cells that the body is infected. This process is called antigen presentation."
"Macrophages are like sharks in our bodies in that they hear all the commotion and come to see what's happening, and like T-cells they too release cytotoxins in addition to prostaglandins."
"Macrophages are like combination reconnaissance and disposal units. They get bits of molecules from invaders and present them to T-cells for identification. They can also surround and digest dead cells and foreign substances in the blood."
"Macrophages are like the roomba of the immune system"
"Macrophages are like teenagers: they want to fit in. And one of the compelling features of macrophages is their ability to model their behavior after their peers (i.e., the social cytokine environment). The "good" macrophages play important roles in fighting infection and invaders, while the "evil" macrophages promote tumor progression. "
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
