Concept in Definition ABC

The immunology is a branch of the biology that deals especially with study the immune system.

It should be noted that the immune system consists of a series of structures, organs, cells, tissues and biological processes corresponding to the inside an organism and that are capable of protecting it from diseases and conditions, killing pathogens that correspond, that is, they provide an immune response to them.

This system is capable of detecting from a virus even parasites in the intestine. It is mostly composed of leukocytes, lymphocytes, antibodies, cells, and neutrophils, among others.

Its main actions include: detailed study and knowledge of the immune system both under conditions of Health like disease, alterations in its functioning, the physical, chemical and physiological characteristics of its component parts.

The immunological action was detected for the first time there far in time, approximately in the year 400 BC in Greece, during the Peloponnesian wars

. In those years it was found that those who managed to recover from infections, from that moment on, were immune to that infection and did not suffer from it again.

Later, around the 15th century, when smallpox was an unstoppable plague, China and Turkey they made the first attempts to artificially produce immunity.

In the 18th century, the English-born physician Edward Jenner would bring more news about it when he discovered that the inoculating someone's body with a virus will end up protecting them from it. Another doctor, Louis PasteurYears later, he would end up confirming this question with his investigations and tests.

The discipline It has advanced so much in the 20th century and in recent years and then today we may find different types of immunology: clinic (studies those diseases that originate from the presence of disorders in the immune system), immunotherapy (deals with the treatment of diseases such as cancer, AIDS), diagnostic immunology (detects the virus from various screening techniques diagnosis), evolutionary immunology (It studies the immune system in species that have already disappeared and in living species, and then offers clues on the matter of evolution).
