Detailed Overview of HIV Essay -- Biology AIDS

Since the onset of the human immunodeficiency virus/acquired immune deficiency syndrome epidemic 15 years ago, the virus has infected more(prenominal) than 47 million people in the world. With more than 2.2 million deaths in 1998, human immunodeficiency virus/AIDS has directly become the fourth leading take in of mortality and its impact is going to increase. Over 95% of all cases and 95% of AIDS deaths occur in the developing world, mostly among young adults and increasingly in women.human immunodeficiency virus can be prevented in many ways, tho if they argon non always followed. People die when they dont play it safe. Thats why we have to spread the word on prevention. There argon trio main ways that HIV can be spread1. inner intercourse2. intravenous drugs3. blood transfusions (which are very rare now because all blood is tested)HIV is ventilation like wild conflagrate among adolescents because they dont believe it can happen to them. Sixty-one percent of 14-21 year olds are engaged in sexual intercourse. The problem we have to deal with is the spreading of this disease among our generation.Scientists are trying to develop a cure for the AIDS virus. There are three part to finding the cure. The three parts are1. To devise a drug that will kill the HIV virus once it enters the body.2. To create a vaccine that would prevent the disease.3. To inculcate people world wide about the dangers of AIDS and how to prevent the HIV infection.In humans, the immune system acts as a line of defense reaction against foreign organisms in the body. Though the immune system functions throughout the body, its drudgery centers from certain key organs in the body.Various specialized cells are produced by these organs and comprise the immune system. For example * Lymphocytes o B Cells o T Cells * Macropha... ...CR5. The CCR5 demonstrated fusion for all of the macrophages-tropic isolates but scarcely at all for the T-tropic iso lates, further supporting previous conclusions on the power of CCR5.Finally the researchers took a northern blot of CCR5 to analysis its RNA. CCR5 RNA was not found in the human cell lines that were tested. The human cell lines were chosen with the criteria that they were not susceptible to M-tropic isolates. Their test further supported the fact that Fusin was use as a receptor for T-tropic virus strains, and when the two strains were compared CCR5 and Fusin are the lone(prenominal) fusion cofactors for HIV.Understanding these coreceptors is very important in slowing pour down the progression of the HIV virus. The HIV virus is irreversible and can only be slowed down. If they can learn more about how the virus enters cells they world power be able to deter the virus.
