Immune Response Against HIV Research Paper Example | Topics and Well Written Essays - 500 words

Immune Response Against HIV - Research Paper Example The immune system is a defense mechanism of a body. This research paper desribes how the immune system works against the invasion and threats of viruses, bacteria and other microscopic organisms recognized as non-self. A good example of a virus that the immune system fights against and is a main focus of this research paper, is HIV (human immunodeficiency virus), which is responsible for causation of AIDS. This research paper gives detailed discussion on the topic and describes a few stages of the fighting against viruses process. During the 1st stage, the phagocytes try to engulf and destroy the non-organic enemies that they detect in the body. Stage II of the fight against viruses takes place after the CD4 have received information concerning foreign invaders in the body. During this stage, the CD4 divides and send signals that activate other components required in the defense system. Terminology of CD4, phagocytes and non-organic are also explained in this research paper. In concl usion, the immune system protects the body from foreigners such as viruses and bacteria. HIV virus is known of invading a human cell and making it a factory for viruses. Its destruction of the HIV virus in the body involves different stages. Phagocytes are involved in destruction of non-organic materials in the body. The macrophages then aid in presenting the information on the virus on their surfaces. The CD-4 then uses the information presented on the surface of the macrophages to activate many soldiers such as killer T-cells.
