Monoklonal antikorlar (monoclonal antibodies) are laboratory-made molecules designed to mimic the immune system's ability to fight off harmful pathogens like virüsler (viruses) and bakteriler (bacteria). They are produced by creating identical copies, or clones, of a single type of immune cell, which allows for a consistent and targeted response against specific antigens. These antibodies are used in various medical applications, including kanser (cancer) treatment, otoimmün hastalıklar (autoimmune diseases), and enfeksiyonlar (infections). By binding to specific proteins on the surface of cells, monoklonal antikorlar can help to mark them for destruction or block their function, enhancing the body's ability to fight disease.
