AIDS Resistance Genes :: Biology

The What aid researchers have recently open a genetic trait that may provide protection against human immunodeficiency virus-1. A defect that could account for unexplained cases of individuals that seem to have an immunity or protection against HIV-1. They are calling the trait an AIDS Resistance cistron. What is an AIDS-Resitance Gene? This is just one of the questions our group inquired about when we began our investigations into the slowlyst of AIDS research.AIDSAcquired immune deficiency syndrome, AIDS, is a serious disease that becomes to a greater extent and more common in our nation and around the world. AIDS is delimit by certain criteria established by the U.S. Centers for Disease Control and cake based on lab evidence such as T4 cellular telephone count, the presence of certain diseases, and other conditions.WHAT CAUSES AIDS?This disease is caused by the virus known as Human Immunodeficiency Virus Type 1 (HIV-1) (Structure of HIV), which attacks cells in the immune s ystem, leading to the systems inability to resist harmful organisms. It damages the cells in the immune system, causing the body to lose the ability to fight stumble infections and diseases. During the course of infection, CD4 T-cells (a special type of infection-fighting white blood cells) are disenable and killed as their numbers decline.From 1981, when the first cases of AIDS were reported, through mid-1995, more than 476,000 individuals had contract AIDS in the U.S. More than 295,000 of these individuals died. These numbers do not involve those infected with HIV. Without symptoms of AIDS, nearly 1 million Americans have been infected with HIV through the mid-1990s. An estimated 19 million individuals world-wide have been infected with AIDS since the late 1970s.HistoryResearch has lead some to believe that HIV arose in Africa from retroviruses of monkeys. It is said that urbanization and the change in traditional lifestyles brought HIV-1 to the cities. It then bedsp read to other parts of the world. However, it is proven that HIV-1 has been in circulation since 1959, because antibodies to HIV-1 have been detected in stored frozen blood samples taken from individuals in Zaire in 1959 and the coupled States in 1968. AIDS was first officially detected in the join States in 1981 in New York and California. In 1981 doctors found what they thought was a rare form of cancer called Kaposis Sarcoma in many males. These patients also had signs of a type of pneumonia called Pneumocystits which occurs when ones immune system is not functioning well.
