Hiv And The First Human Immunodeficiency Virus

As stated by Dr. N.A.S, finding a vaccine has been incredibly challenging due to the astonishing genetic diversity of the virus. While it is true that the genome of two HIV infected individuals can differ by up to 30%,6 it is not the integrase enzyme that causes this huge difference in the genomes as written by Dr. N.A.S. Reverse transcriptase is the error prone enzyme that makes multiple mistakes while copying RNA into DNA, which results in ~1 mutation in every new virus.6 The advantage of mutations for HIV is that these new changes are not

In the 1980s, a mysterious disease began to take the lives of Americans. With the cause unknown, a fear grew among Americans. An unusually high rate of people was becoming sick with strange and rare diseases. When experimental treatments failed to work, people died. This mysterious disease is what we now know as HIV–Human Immunodeficiency Virus. In the past thirty-five years, the HIV has taken many turns in history. Although we do not hear about HIV and AIDS now, it is still a prevalent issue in the United States and in the world.

As have been described above, HIV can have a potential effect on immunological cells, which are important to protect the body from additional infections such as Tuberculosis (TB), Cytomegalovirus (CMV) and other viral or bacterial infections. An effective treatment is needed to reconstruct what HIV has damaged. Antiretroviral therapy (ART) is a common treatment to stop the viral replication and decrease the disease progression, which may lead to a vast decline of the morbidity and mortality. The standard treatment involves a combination of at least three drugs; often known as a highly active antiretroviral therapy (HAART) where the most common types are Nucleoside reverse transcriptase

function that selectively infects helper T cells” (545). My goal in this paper is to show the advances

HIV is a life changing virus that cannot be reversed. It can be spread by “semen, vagina fluids, breast milk, or amniotic fluid”. This virus is a vicious virus that harms and fights the body immune system. The immune system is the body’s healing system that fights off diseases. With a weak immune system, one is more likely to become infected with diseases and illnesses. There is treatment to help aid the symptoms of HIV, but unfortunately there is no prevention vaccine for HIV.

Unlike the plague, the Human Immunodeficiency Virus is species specific and has puzzled many scientist about the possibility of overcoming its harsh implications. This mean that HIV can be found only within a particular species and, in this case, this virus tends to attack the human race. Many blame that the very existence of AIDS emerged from gay people or relations with animals, but it’s believed that transmission of this virus originated from a close derivative of HIV, SIV. SIV in known as Simian Immunodeficiency Virus which the Monkey virus that is equivalent to HIV. It has been known that the development of AIDS started with the transmission of SIV to humans via being bitten by a primates or the consumption of a primate who is infected

Advertisement objective: To against AIDS and to prevent HIV virus spread out, since no vaccine to cure AIDS’s infection.

Further, if we produce more effective drugs rather than placebo drugs in certain cases, the infected individuals could effectively respond to them in a positive way. Using the placebo effect has many disadvantages: deception and expensive payments. Some of these controlled medications could revert and harm the patient. One major way of improving the prevention of AIDS is effective vaccinations. Vaccines can potentially be the solution to destroy HIV; however, vaccines can become so obsolete since the virus contains foreign antigens. Thus, these different antigens make it difficult for the antibodies to directly bind to them. As for infected pregnant women, I believe that an advanced vaccine could be immediately inserted in the placenta to reduce the likeliness of the infant receiving the infection from blood transfusion. Scientists should create specific antibodies that could bind to this “smart” virus. They should also improve the consistency of these vaccines so that they could be active constantly. Once bonded, the virus will then be ineffective in destroying the immune

In 1985, over 10,000 cases of AIDS were reported worldwide (White and Fenner 1986). Just over a decade later, in 1998, the Global AIDS Policy Coalition estimated that 30.6 million people were infected with HIV worldwide. It has also been projected that by the year 2000, between 40 and 70 million adults will be infected with HIV (New Generation Vaccines 1997). Over 90% of all HIV-1 infected individuals live in developing nations: 50% in Southeast Asia and 40% in sub-Saharan Africa. However, even with all of these alarming statistics and projections, there is hope for the future of humanity. This hope is a potential anti-AIDS vaccine. An anti-AIDS vaccine is the best bet. Among other factors, the large costs associated with therapeutic

The most fundamental question to ask about an HIV vaccine is: 'What evidence exists that protection against disease after exposure to HIV is possible?' The best evidence for successful protection against a virulent primate lentivirus such as HIV is that monkeys are almost always protected against challenge with pathogenic SiVmac after vaccination with an attenuated (ne/-deleted) SIVmac

Introduction: Human Immunodeficiency Virus (HIV) has become a global issue that has infected an estimated 35 million people living today1. The strain HIV-1 has been of experimental concern for years in hopes of a cure. This retrovirus directly infects the immune system by binding helper T-cells via the CD4 receptor. This allows for integration of the viral RNA into the T-cells, and causes the immune system to weaken by killing these immune cells. Advancements in research led to the use of highly active anti-retroviral therapy (HAART) for treatment, however this does not cure the patient of HIV but it suppresses the viral replication of HIV-1 to very low levels2.

The goal of this experiment is to prevent HIV through vaccination using ex vivo gene therapy.

HIV, a lentivirus causes AIDS through interaction of the different cells in the body mainly the cluster of differentiation 4 (CD4) molecules on cells and other cellular receptors (Levy, 1993) particularly responsible for the host’s immune system. Once HIV entry has occurred, the virus starts to destroy the host’s CD4 cells and replicates using an enzyme called reverse transcriptase and converting its ribonucleic acid (RNA) into a deoxyribonucleic acid (DNA) (Heymann, 2015). In addition, the ability for the HIV to break the long chains of protein that form the virus using an enzyme protease promote viral replication in the same manner as the body’s own immune system.

Currently, there are no vaccines and no cures for HIV or AIDS, although scientists are researching and finding new drugs and treatments. So far, scientists have discovered a variety of drugs and medication that can be used to control and slow the virus and the progression of the disease. There are some drugs which interfere with the virus ability to make copies of itself by disabling a protein it needs, like Non-nucleoside reverse transcriptase inhibitors. If someone is diagnosed with HIV, it is important to start with treatments as soon as possible.

Vaccination has gained great recognition as the most effective way of controlling and managing several fatal health conditions. Thanks to Edward Jenner’s successful attempt on small pox, vaccines have been designed to help protect the human body against many diseases that would have otherwise caused massive deaths across the world (Macaulay, 2016). Think of what would have happened if all of these diseases were not prevented, and had to attack someone so that they are dealt with such as the case of the AIDS disease. It is very evident that once a disease has found its way into the human body, it acts as a trigger to several other issues that affect the various aspects of human life. Metzl and Hansen (2014) mention that diseases are normally in a complex relationship with every aspect of human life, and preventing them is very necessary. This is where vaccination comes handy. The development of HIV/AIDS vaccine, therefore, would be a great step in establishing significant resolutions to the current
