Page 35 - The Miracle of the Immune System

ntibodies are protein-structured weapons, which are manufac-
tured to fight against the foreign cells entering the human body.
These weapons are produced by the B cells, a class of warriors of the im-
mune system.

Antibodies destroy invaders. They have two main functions: The
first is to bind to the invader cell, which is the antigen. The second is to
decompose the biological structure of the antigen and destroy it.
Swimming in the blood and non-cellular fluid, antibodies bind to
disease-causing bacteria and viruses. They mark the foreign molecules to
which they bind, so that the body’s fighter cells can distinguish them. This
way, they also inactivate them. This resembles a tank becoming useless
and unable to move or fire shells when it is hit by a guided missile in the
battleground. An antibody fits the enemy (antigen) perfectly, just like a
key and a lock assembling in a three-dimensional structure.
The human body can produce a compatible antibody for almost ev-
ery enemy it encounters. Antibodies are not of one type only. According
to the structure of every enemy, a specific antibody powerful enough to
deal with it is produced. This is because an antibody produced for one

disease may not be effective on another.
Manufacturing a specific antibody for each enemy is rather an unu-
sual process, which deserves closer attention. This process can be realized
