It is defined as the continuous stimulation of the immune system, so that its conditions improve and it can fight against infections or diseases, in addition to helping to overcome the side effects of aggressive treatments against cancer.
Its use can be preventive or healing, the first being a method to enhance the performance of the immune system and thus avoid complications when using a powerful treatment. The immunomodulators, meanwhile, are molecules that remain implicit and active during immunotherapy, more easily recognized cytokine main in use so far.
Mainly, it was designed so that the body could fight cancer cells. The first case of this type of treatment was registered around the year 1890, in which Streptococcus pyogenes was introduced into a tumor and it caused its regression; however, open knowledge about the technique came to light 100 years later. Different techniques are currently being investigated to find new types of immunotherapy, which would use cells similar to the cytokine, in addition to developing methods to allow tumor tissues to express themselves the different types of cytokine, self-destructing.
Immunotherapy based on dendritic cells proposes the use of them as a means to generate a cytotoxic response induced towards an antigen. They are produced by the patient, but a viral vector is needed to drive them. For its part, immunotherapy based on T cells, which consists of extracting them and, contrary to different methods, all the reactive powers that these have against cancer can be expanded, to later be implanted in the needy patient.
