"The complement system is like a molecular alarm system and first responder, Grice explains. "It leads the counterattack against microbial insult." The system is an evolutionarily ancient branch of the immune response and a key function is marking microbial and dying host cells for elimination."
"The complement system is like a Rube Goldberg Device Similar in that it is circular, hard to know where it begins and it is extremely complicated can never understand a component of the pathway without knowing what is upstream/downstream of that specific component"
"This complement system is like a sword which is sharp at both edges. Excessive activation of the complement leads to various disease like rheumatoid arthritis, glomerulonephritis, multiple sclerosis and other inflammatory diseases."
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.
