The immune system is made up of many types of cells that communicate with one another using, for example, hormones, cytokines, growth factors or neurotransmitters. These “messengers” also enable them to interact and coordinate themselves with other organs and systems, such as the nervous or the endocrine systems.

Through this communication and exchange of information, our body is able to defend itself against potential aggressors such as viruses, bacteria, fungi, toxins or tumour cells, and perform their functions correctly.

It is a dialogue that occurs naturally and in perfect harmony, and enables the body to be unrelenting towards damaging agents and tolerant towards elements that make up our tissues, or that are beneficial for us, such as intestinal flora. This, however, is reliant on a very fine balance.

Factors such as stress, poor diet, genetic alterations, age, the microorganisms themselves or even pollution can throw things off balance and, when this occurs, the functions of the immune system are impaired, and this is when disorders arise.

For example, in autoimmune diseases the immune system mistakenly attacks its own tissue, and in infections or cancer, it is unable to keep the multiplication of the infectious agent or tumour cells respectively under control.
