When E-antibodies bind to metastases, Basophils and Antigen Presenting Cells, substances such as histamine are stimulated, Cytokines, and other substances that stimulate the initiation of hypersensitivity reactions. The secretion of such substances leads to a variety of symptoms in the body's various organs, which vary according to the body's interaction with these substances, such as stimulation of sneezing, redness and swelling of the eyes, difficulty in breathing, itching or rashes in the skin, abdominal cramps, diarrhea and esophagus, Sudden stop in the work of the circulatory system or respiratory system
