What is an antibody?
An antibody is a protein that has a protective function in the body, which is produced by the immune system.
An antibody attacks an antigen (foreign body), for example, bacteria, fungi, viruses, toxins, and expels it from the body.
Antibodies are produced by leukocytes.
Antibodies are located in various parts of the body, for example, in the skin, lungs, saliva, and breast milk - here, they accumulate in the largest quantities, and that is why doctors believe that breastfeeding improves the baby's immune system.
A monoclonal antibody is developed and produced in a laboratory. It imitates the natural ability of the human immune system and fights pathogens. Monoclonal antibodies, as a type of immunotherapy, are designed to fight infections.
Monoclonal antibodies may be used in the treatment of the following diseases:
- Cancer;
- Heart disease;
- Rheumatoid arthritis;
- Multiple sclerosis;
- Lupus;
- Crohn's disease;
- Psoriasis;
- Transplant rejection.
