Immunodeficiency Virus

Good Essays
Human Immunodeficiency Virus (HIV) is a lentivirus that attacks the body’s immune system through CD4 cells and evolves into Acquired immunodeficiency Syndrome (AIDS). HIV is transmitted by contact with bodily fluids. Symptoms of HIV are similar to simple cold symptoms including fever, chills, rash, etc. There is no cure for HIV, but it can be treated and controlled with antiretroviral therapy. There will be a more in-depth look into HIV in this paper.
Human Immunodeficiency Virus: Causes, Effects, and General Information Almost 37 million people today are living with Human Immunodeficiency Virus (amFAR, 2016). Human Immunodeficiency Virus is a lentivirus that affects our immune system. HIV is an easily contracted virus and was the cause of

More specifically, our CD4 cells. The Immune System in our bodies works to prevent infection. The Immune System can recognize our healthy cells from cells that have been damaged or infected. The Immune System has many parts to it to help your body fight off and prevent infections, these parts include Skin, Bone Marrow, Blood Stream, Thymus, Lymphatic System, Spleen, and Mucosal Tissue (National Institute of Allergy and Infectious Diseases, 2013). One of the major parts of the Immune System we will be looking at is the CD4 cells. There are four kinds of CD4 cells (TH1, TH2, TH17, and Treg) that are white blood cells that all work to stimulate a response in the Immune System. All CD4 cells are important in stimulating a response from the immune system of other immune cells or systems to prevent and fight off infection by secreting molecules that set off the Immune System (National Institute of Allergy and Infectious Diseases, 2013). Human Immunodeficiency Virus works by affecting the CD4 cells. HIV has seven steps in affecting CD4 cells. First, the HIV Virus binds with the CD4 cells and fusses with the cell. Then, an HIV enzyme is released into the cell and inserts the HIV DNA into the cell’s DNA. The HIV then uses the CD4 protein to replicate and then releases itself to infect more CD4 cells (AIDSinfo, 2015). If the HIV goes without treatment the HIV will destroy all CD4 cells so that the Immune System can no longer prevent and fight infection. This Causes Acquired Immunodeficiency Syndrome

    [5] Based on the CDC, Centers for Disease Control and Prevention, HIV is a virus that spreads through specific fluids of the body’s immune system. It specifically targets the CD4 cells of the adaptive immunity, which is also known as the third barrier of the immune system. Over a period of time, HIV destroys so many of these cells that the body cannot fight off infections and diseases anymore. CD4 T cells are essential for the body. They are used to organize the…

    HIV (also known as the human immunodeficiency virus) is a virus which targets and attacks the immune system which in turn weakens your ability to fight infections and disease. If left untreated the HIV can lead to a disease called AIDS (which is known as the acquired immunodeficiency syndrome). HIV affects the specific cells of the immune system which are called the CD4 cells and if left untreated, HIV can eliminate so many cells from the body and ultimately the body cannot fight off other infections or disease. There are many symptoms/signs that you may have HIV. Within the first month or two upon catching HIV, almost 40% to 90% of people experience flu like symptoms which is known as ARS (acute retroviral syndrome).…

    2014). HIV uses the chemokine receptors CCR5 and/or CXCR4 to infect the CD4+ T cells, virus using only CCR5 receptors called R5, those using only CXCR4 called X4 and those using both called X4R5; once the chemokine receptor has latched onto the virus takes control over the T cell using it to produce more copies of the itself (Coakley E, Petropoulos CJ, Whitcomb JM, 2005). Transmission from person to person is able to happen due to the fact that T cells are present in blood therefore when two persons exchange bodily fluids, like blood, they receive the T cells infected with HIV and then they themselves are infected with the virus. HIV is transmitted…

    Recently developed vaccines 5.1. Targets for malaria vaccine Malaria vaccine have three target stages including pre-erythrocytic stages, erthrocytic or asexual stages, and sexual stages. Pre-erythrocytic vaccines are directed against either the invasive sprorozoite or the early stages of development in the liver. Asexual stage vaccines are directed to kill intra-erythrocytic parasites or prevent invasion of erythrocytes by merozoites. Finally, sexual stage vaccine designed to stop mosquitoes from becoming infected by preventing parasite fertilization in the insect vector (Greenwood and Targett, 2011).…

    This process is called Antiretroviral Therapy (ART). Some examples of antiretroviral medications include Nucleoside/non-nucleoside reverse transcriptase inhibitors also called “nuke” that help block the most important step of HIV reproduction process. These two medicines block the enzyme reverse transcriptase and prevent the virus from making copies of its DNA. Another include protease inhibitors that blocks the strands of DNA from getting cut into functional pieces. A third medication is called Fusion inhibitors that blocks the virus from entering the cells.…

    This process is known as attachment. After attachment the viral and host membrane fuse, a process known as fusion, and then the viral contents are emptied into the host cell, a process known as entry. After entry the HIV virus transcribes its RNA into DNA and integrates its DNA into the host cells chromosome. From this point the virus may lay dormant in a period of latency or it may signal for the production of new viruses to continue infecting other T helper cells (Tortora et al., 2013, p. 545-547). Currently there is no cure for HIV but with the advent of new drugs it has become a chronic infection that infected…

    One way to be tested for aids is to test the person 's blood or saliva for antibodies against the virus. However, you could be positive and the test could come up negative because it takes up to 12 weeks for your body to develop the antibodies. Clearly, a virus in which lowers the body 's immune response will have some complications. There are numerous amounts of infections or malignant diseases you could acquire due to aids, but I will name the more common types of infections or diseases. In no order, tuberculosis which is an opportunistic infection, cytomegalovirus which is simply herpes passed on through bodily fluids, cryptococcal meningitis, toxoplasmosis if the person is or has been exposed to any cats or cat feces, and candidiasis.…

    They contain a fragment of genetic material inside a protective protein coat. Viruses can only reproduce when inside a host cell, they damage the cell when they do this. Once a virus has entered a cell, it has the power to take over and make hundreds of copies of itself. Eventually the copies of the virus fill the whole host cell, causing it to burst open. The viruses then bleed out into the bloodstream or by…

    HIV stands for human immunodeficiency virus. This is a virus that attacks the immune system. Originally isolated in Paris in May 1983 by Luc Montagnier, HIV belongs to a group of viruses called retroviruses. Viruses copy their genetic material into the genetic material of human cells, meaning infected cells stay infected for the rest of their lives. Viruses cannot replicate outside a living cell.…
