Vaccine: Immune Strengthening Method

What is it - biological definition

Antibody is a specific protein that reacts only with the foreign body against which it was produced.

Action, antibody function and main characteristics

In the case of an insect bite, the body will produce antibodies against its antigens, that is, if you are bitten by a rubber, the antibodies produced will only combat the effects caused by the rubber, not being used to bite any other insect.

Antibodies act by adhering to the surface of the foreign body, this prevents the multiplication of microorganisms and inhibits the action of toxins.

The antibody reaction against the foreign body is called antigen-antibody reaction, which attracts macrophages that phagocyte both the antibody and the foreign body. After this procedure, the macrophage self-destructs (this process is known as autolysis).

The action of antibodies begins very early, yet in the intrauterine phase they already start working copying and storing all amino acid sequences in the body of the fetus.

How it acts in the body

After birth, it will act in defense of our body as follows: through the vigilant action of the C lymphocyte, which after being attracted to the places where there was cell death, will make the recognition of all proteins (amino acids).

In the case of physical trauma, lymphocytes will not find unknown proteins and only then will they attract neutrophils (cells responsible for tissue repair) to the region.

However, if any unknown protein is found, the lymphocyte will release histamine to attract other lymphocytes to the region (this process is known as chemotaxis). This is because a single lymphocyte does not know all the proteins in our body, but several together know the entire amino acid sequence of our body.

If after this binding the protein is still unknown, another type of lymphocyte (T lymphocyte) will be attracted to the region for the purpose of prototyping an antibody, however this process will not always be rapid.

After the prototype has been created, the T lymphocyte is rapidly multiplying and producing a large amount of antibodies. At this stage, the lymphocyte will be called plasmocyte.

After all this process, there will be the step already mentioned in the third and fourth paragraph of this text, when the initial purpose was to make an introduction to all this described path.
