Assignment 11: HIV and Helper T Cells
T Cells are the first to be impacted by an HIV infection that enters a host. Helper T cells - which originate in the lymphatic tissue - are critical to immune system functioning, and assist in a variety of different ways. First, Helper T cells produce cytokines, which are chemical messengers that alert other members of the immune system that the body is under attack from an antigen. Helper T cells activate B Cells, which are another “flavor” of lymphocyte. The B cells will develop a clonal line that produce both plasma (antibody-carrying) and memory B cells, both of which are critical in immune defense and a faster recovery period in incidences of future repeated infection.

    They recognise the same protein that activated T cells. B cells produce antibodies that are the same as T cell receptors as they precisely recognise the protein belonging to the pathogen. The antibodies are then released from the B cells into the blood. They will then meet the pathogen and attach themselves onto it. Killer T cells activate as well if the pathogen is a virus. This enables another series of events which will destroy bacteria. When the bacteria are destroyed, the activated dendritic cells remain in lymph nodes and the B cells remain in contact with it, co-operating with it to ensure that the immunity is conserved. When the human body is healthy, the immune system has many cells ready to activate in case of an infection. When the battle is done, the cells will then deactivate slowly and some…

    Unit 9 Assignment 1: Sexually Transmitted Infection

    There is no cure for this disease, but medical advancements have produced treatments and therapies that allow infected individuals to function fairly normally and extend life expectancy. AIDS can be spread through any sexual contact as well as through blood via transfusions or needle sharing and from a mother to fetus or newborn. Initial infection may present flu-like symptoms. These include: diarrhea, fever, headache, sores, muscle soreness, rashes, sore throat, night sweats and swollen glands. However, many diagnosed with HIV/AIDS may present with no symptoms. In addition, it can be as long as 10 years before the virus is detected after infection. Most who become infected with HIV will develop AIDS eventually. Once the virus had progressed that far the immune system is significantly compromised and the individual is susceptible to many other threatening illnesses, particularly opportunistic infections. The long term effects of this syndrome include a plethora of medication and therapy to attempt to protect the body from illness and infection. Also, it is important for the individual to be aware and careful to prevent infecting others (HIV/AIDS…

    Mmhc Class 1 Essay

    After a viral infection, infected cells release cytokines. These are stress molecules which notify the immune system cells about the presence of virus in the affected area. NK cells activating cytokines are IL-12, IL-15, IL-18, IL-12 and CCL5. Cytokines released form interferons and macrophages are a principle source of NK cell activation. They then prevent the viral infection from spreading so that cytotoxic T cells can eliminate them. IFNγ and TNFα are released by NK cells to curtail viral infection. Macrophages activated by IFNγ phagocytose and lyse the virus infected cells. TNFα on the other hand influences NK cells to kill tumor cells. It has been also found that deficiency of NK cells increases the chances of herpes…

    The Morphology of the Lymphatic System

    B cells (B lymphocytes) are an important component of the immune system. They are responsible for making antibodies against antigens. B cells are produced in the bone marrow they either stay there or move into the thymus gland, where they become T cells. T cells (T lymphocytes) acts as soldiers, they destroy “invaders” or foreign antigens. B cells acts as the body’s intelligence system. When foreign substances are detected cells work together and they respond by triggering b cells to produce antibodies. This is also an example of how shots prevent diseases.…

    The Involvement of Canadians in a Particular Global Health Problem or Issue

    Human Immunodeficiency Virus (HIV) is a virus that affects the human immune system and leads to a stat makes the patient unable to fight against diseases and so opportunistic diseases such Tuberculosis and others affect the individual (Worthington et al., 2010). HIV/AIDS was first realized in 1981 by the Center for Disease Control and Prevention and is believed to have originated from West-Central Africa. HIV/AIDS has been termed as one of the greatest causes of death in the global society (Gibbs, 2010). The virus is spread when body fluids of a victim gets into contact with the body fluids of another person. Due to the nature of the disease, even unsuspecting individuals such as patients undergoing blood transfusion, unborn babies and others can become victims. HIV is primarily spread through sexual intercourse without any form of protection (Ford et al., 2007; Gardezi et al., 2008).…

    How Does Haiti Affect America

    AIDS is the acquired immunodeficiency syndrome where the immunity is severely damaged and lowers the bodies ability to resistance infection. HIV is the virus that causes AIDS. Fluid from an infected person much encounter a mucous membrane, the bloodstream, or a cut or injured area of another person to transmit the virus ((Davis). Early symptoms include fever, headache, fatigue, swollen lymph nodes, and a sore throat within two to four weeks of being infected. There are three phases to the disease. Thee first stage includes the acute infection and many people do not experience any symptoms. The second stage is known as clinical latency and means that the virus is dormant and reproduces much slower rate than in the acute phase. The second stage can last for one decade although it sometimes progresses faster. The third stage is AIDS. Individuals have low T-cell counts and compromised immune system that make them easily susceptible to infections and cancer (Davis). Social and economic consequence of HIV include loss of job and income, decreased family income, increased expenses for seeking care, and greater economic consequence, shown by selling assets. Those with AIDS deal with the social measures of being discriminated against along with their physical, mental, and social wellbeing. The disease can lead to a weakened family support…

    Second Line Of Defense

    The two cells have different responses, the T-cells are involved in a cell-mediated response, while the B-cell are involved in the humoral response. During the process of the T-cell response there are many different variations of the T-cell such as the killer T-cell, helper T-cells, suppressor T-cells, and memory cells. By using cytotoxic T-cell, the third response is able to detect and recognize antigens on the surface of infected cell. The cytotoxic T-cells then bind to the infected cells secrete cytotoxins that induce apoptosis in the infected cell and perforins that cause perforations in the infected cells. When both of these mechanisms are through they will help destroy pathogens in the infected body. This diagram will help with the visualization of these mechanism and their processes. Killer T-cells combine with antigens on the surface of any invading cell and release a powerful group of chemicals called lymphokines. Some lymphokines kill the pathogens directly, others stimulate lymphocytes to become active and help increase the inflammation so that there are more macrophages. Helper T-cells co-operate with B-cells in the antibody production. They also activate macrophages and promote inflammation. Memory cells remain even after the pathogens have been killed to stop…

    How Hipaa Violations Affect the Medical Billing Process

    AIDS is caused by a retrovirus known as HIV, which infects and kills the T-cells of the body’s immune system. HIV destroys CD4 cells, which is a type of white blood cells that helps the body fight diseases. The more CD4 cells that die, the weaker your immune system will be. As the CD4 cells are destroyed by HIV, the body will begin to develop other infections that would not normally affect it therefore making those who suffer from AIDS unable to fight off infections. In order to become infected with HIV, vaginal secretions, semen, or infected blood must enter your body. A person can’t catch HIV from ordinary contact such as hugging, kissing, or even shaking hands. HIV can also not be transmitted through, water, air, or even a mosquito bite.…

    Human Immunodeficiency Virus (HIV) is a virus that only affects humans, HIV weakens your immune system by destroying the cells that fight and kill disease and infections. HIV reproduces by taking over cells in the host’s body and multiplying, with most viruses over time the immune system can rid the body of the present virus, with HIV the immune system is incapable of doing this, therefore it is a virus that will always be present once infected.…

    Black Death Impact

    It occurs when an HIV positive person’s T-cell count falls below 200 cells per cubic millimeter of blood, compared to the normal 500 to 1600 cells per cubic millimeter of blood. Disregarding T-cell counts, AIDS can also occur if if an HIV infected person develops one or more “opportunistic infections,” which are illnesses that develop due to weakened immune systems that would normally not bring about a disease. Not every person with HIV has it progress into AIDS, but for those who do, one is expected to live only for another three years, unless the person develops a dangerous opportunistic infection that can reduce their life expectancy even further (What is…

    Infectious Disease WK2

    HIV is the virus that leads to AIDS, which is where the disease originated. Being that there was a virus that started the disease this is where the inflammatory response started. The inflammatory response originates when tissues of one’s body are injured by bacteria, trauma, toxins, and in this case a virus. Your body’s immune response should protect you, but when it no longer can protect your body from the virus of HIV, then the inflammatory process begin. The virus attacks the CD4 T lymphocytes, destroying them and also killing others (Zelman Ph.D., Tompany PharmD, Raymond Ph.D., Holdaway, MA. P., & Mulvihill, Ph.D. 2010). That entire process paralyzes the immune system by making the body susceptible to infections and illnesses that a healthy immune system would be able to control. While the body is going through this, the immune system becomes weakened and eventually open to infections and leads to inflammation mainly in one’s lymph nodes and stomach.…
