They Fly The Cellular Plane....

a: T4 lymphocyte ~
b: a pilot of immunity

What: The T4 lymphocytes are like the "pilots" of immunity. The T4 cells also govern the quality and quantity of the B-lymphocytes. Thus, with progression of the infection over the years, the patient has defective cell mediated immunity and lymphokine mediated humoral immunity. This is responsible for the increased incidence of opportunistic infections as the patient's immune system deteriorates.

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.
