What if the
War in the Body Were Left in the Control of Human
People do not immediately realize
that microbes or viruses are invading their bodies.
Only when the symptoms of their illness surface do
humans become aware of them. This is proof that a
virus, a bacterium, or a similar micro-organism has
long ago settled within their body. This means that
the primary intervention has resulted in failure.
Such unchecked conditions could cause the disease
to progress considerably, resulting in irremediable
dispositions. Even if the person has been infected
with a curable and relatively simple disease, delayed
response may result in a serious crisis, or even death.
Now, let us imagine that the coordination
and control of the elements of the defence system
and the ensuing strategies to be developed and implemented,
the overseeing of the war itself were all left to
human beings. What sort of difficulties would we confront?
Let us assume that the initial symptoms
were effectively diagnosed. When foreign cells enter
the human body, immediately the warrior cells must
be manufactured and then sent to the area of conflict.
The B cells must immediately commence the production
of the weapon (antibody). How are we to determine
the type and location of these foreign cells? This
is a significant point, as future treatment depends
on this initial stage. To do this, the only solution
for the person would be to have a medical check-up
which covered all the organs of his body down to every
drop of his blood at the slightest suspicion of invaders
having entered the body. Otherwise, it would be impossible
to determine the type and location of the antigens.
The long time needed for such a process would undoubtedly
cause a serious delay in timely intervention. It is
evident how troublesome and distressful life would
be for people if they had to go to the doctor's to
undergo such a check-up on the merest hint of infection.
Let us suppose that timely intervention
was possible and the type and location of antigens
could be identified precisely. Depending on the type
of the enemy, first the phagocytes have to be activated.
How can phagocytes be directed to rush to the exact
location? What kind of a message would help them to
locate the enemy easily? Let us suppose that the impossible
became the possible. Then comes the time to learn
whether the phagocytes have won the war or not. Depending
on the result, either the macrophages will be launched
or the war will be stopped. No doubt, the only possible
solution lies with visiting the doctor again and having
a thorough check-up. If the war has not been won,
the secondary forces, that is, the macrophages, must
be sent to the area of conflict. Meanwhile, the time
spent on the check-up would work against us. Without
losing any time, the macrophages have to tear a piece
off the enemy and warn the helper T cells. The helper
T cells will in turn warn the killer T cells, thus
initiating another struggle. These cells, too, must
be checked on as to whether they are successful or
not - for which, again, a doctor's help is needed
- and then the NK cells must be called in for assistance.
After a final examination, it will be determined if
the defence system has been effective in defeating
If man were asked to control only
his defence system and nothing else, he would have
to be involved in such a complicated and difficult
process. Even a simple common cold would require him
to go to the doctor's many times over, follow up the
recovery course of the cells with extremely advanced
medical equipment, and direct them as necessary. Even
the slightest delay or a problem in the course of
the process would cause the illness to be further
What if man were asked to form these
cells, make them recognize the enemy and manufacture
the appropriate antibodies, then teach and organize
all the processes they would perform … Unquestionably,
such a life would be far more troublesome and distressful
than the aforementioned model. It would literally
God has taken the burden of this
process away from humans, creating a faultless system
to work in the most immaculate and independent manner
ever imaginable. Just like everything else in the
universe, our defence system, too, has obeyed its
purpose of creation to become an indispensable, critical
element of life:
Hearkening to its
Lord as it is bound to do…(Surat al-Inshiqaq: 2)
We have explored in previous chapters
how the defence system distinguishes between friendly
and hostile cells with the help of the receptors.
However, the building blocks of some hostile cells
are almost identical to those of certain tissues in
the human body. This represents a significant problem
for the defence system, which might conceivably attack
some of its own tissues accidentally.
Under normal conditions, though,
such a response never happens in a healthy human body.
The defence system never attacks a molecule, cell,
or tissue of its own. In medical terms this phenomenon
is referred to as "tolerance".
This constitutes an extremely important
miracle. We can clearly see that the defence system
is fully capable of differentiating between thousands
of proteins. For example, the defence system must
distinguish the haemoglobin found in blood from the
insulin secreted by the pancreas and from the vitreous
humour contained in the eye, and indeed, from everything
else in the human system. The defence system knows
that while it fights a merciless war against foreign
molecules, it must not harm any tissues belonging
to the human body.
many years, researchers have tried to understand how
the defence system has learned to be tolerant towards
its own tissues. Yet, details concerning why the most
important lymphocytes, namely, the T and B cells,
do not attack the human body have only been revealed
in the last 20 years. The tolerance process, only
a small portion of which mankind has been able to
discover as the result of years long research, has
been in operation since the human being came into
How then has the defence system possessed
the ability to distinguish the various different structures
from each other? Can this be the result of unconscious
coincidences as the theory of evolution suggests?
It is certainly impossible for structures made up
of unconscious atoms to coincidentally acquire this
selection ability that requires such consciousness,
information and intelligence.
When specially designed structures
of lymphocytes enabling them to make the right choise
is investigated, it will be understood how illogical
and unreasonable the claim of evolutionists is.
A defence cell developed within the
bone marrow or the thymus would be killed or inactivated
if it reacted to the products of the body. A mature
lymphocyte faces the same consequence in case it attacks
the body's own products. That is to say that any element
of the defence system likely to harm the body is either
killed or forced to commit suicide obeying the command
However, if a T cell is confronted by another body
cell, it does not attack but rather inactivates itself.
Similarly, if there is any substance in the body that
carries antigen properties which should not, however,
be destroyed, the human body does not produce any
antibodies and so does not attack it.
If we consider the fact that our
body contains around 1 trillion lymphocytes, we can
appreciate the miraculous discipline required to ensure
that these cells only target enemy cells and spare
