"Hovanessian says that CD4 receptor is like an anchor on the cell, to which HIV attaches, while CD26 is the door through which it enters. CD26 reacts with a part of the virus's protein coat called the V3 loop. Hovanessian says that this sequence is like the key which opens the CD26 door."
"HIV attaches to a site on our T-cells called the CD4 receptor. T-cells are the soldiers of the immune system that enable us to fight infections. The CD4 receptor is like a window through which HIV enters into body cells. But for efficient entry, HIV attaches to another spot on our T-cells called the CCR5 co-receptor. The CCR5 molecule acts as the most efficient door through which HIV enters into our T-cells. "
The HIV virus sticks to it and goes inside.
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.
