AP2 Unit 3 discussion on Organ Transplantion
In this unit’s readings contained information about the four varieties of grafts. They are and definition are as follows: Autografts which is a transplant procedure where one 's own tissue is used to grafts for burns and plastic surgery. Isograft is a procedure where tissue from an identical twin is used for a tissue transplant. Allograft is a procedure where tissue from different genetic donor but is the same species as the recipient. Xenograft is a procedure where tissue of a different species such as pigs or cows are used on humans for severe burns.
2. Describe how and why both types of adaptive immunity can cause problems with organ transplantation.
Both types of adaptive immunity can cause problems with transplanted organs because they are systems created to help maintain homeostasis within the body. Cytotoxic T cells are part of the cell - mediated type of adaptive immunity. These cells are activated when specific foreign cells are detected in the body. They are cells that directly attack invading antigens within the body. (Tortora, 2014) Antibody-mediated immunity contains B cells that transforms into plasma membrane that synthesizes and secretes antibodies that bind to and deactivate specific antigens in the bodies fluids. (Tortora, 2014) An organ transplant cells usually is recognized in the body as non-self or foreign and provokes the adaptive immunity to respond with antigen fighting cells and plasma. Because both types work together to fight of antigens, they both can be troublesome for a transplant recipient ability to heal. (Tortora, 2014)
3. Discuss how the body works to recognize your own cells and to differentiate them from foreign body cells.
The body is able to recognize its own cells and differentiate them from foreign cells by developing self-recognition and self-tolerance during the developmental generation of the B and T cells. (Tortora, 2014) There are two processes that take place during the development of the B and T cells,

    According to WebMD, organ transplants are “the surgical movement of a healthy organ from one person and its transplantation into another person whose organ has failed or was injured.” The first organ transplant was conducted on December 23rd, 1954. Dr. Joseph Murray and Dr. David Hume transplanted a kidney from Ronald Herrick, into his brother Richard. The first successful tissue transplant was a skin graft, performed in Germany in 1823.…

    An organ transplant is a surgical procedure to replace a failing or diseased organ with a new, healthier organ from a donor; there are two types of organ transplantation, a cadaveric or living tissue graft. Organs such as the heart, kidney, liver, small bowel, pancreas, corneas, heart valves, bones, skin, bone marrow or lungs can be used, the organs in highs demand are the kidney, heart and liver . These organs can come from deceased donors or living donors. Australia is currently one of the world leaders in organ donation as less than 1% of all organ receivers have died in hospital. Organ donation in Australia is currently voluntary.…

    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…

    There are a few routes that sensitization to non-self human leukocyte antigens (HLA) occurs (Fuggle & Martin, 2008). This article shows that 23% of renal patients that are awaiting transplantation are sensitized. More females than males have the HLA antigen. It also shows that first time transplants have less HLA antibodies than those that have had transplants in the past. Several approaches to transplant sensitized patients are presently used or have been used in the past. It is important to understand the different techniques but knowing why is just as important.…

    Liver is one of the most important organs in human body, it helps in fighting infections, metabolizing drugs by producing enzymes, and synthesizing proteins like, albumin. Liver failure happens When the liver cannot adequately functions and it is life threatening condition if it’s not managed immediately, it might cause some complications, like cirrhosis, hepatitis and multi-organ damage.(1)Liver transplant might be a lifesaving solution with liver failure, unfortunately liver transplant have its own complication like, acute or chronic rejection, and graft loss. Although liver is considered an immune privileged organ due to t cell role in immune response ,though we must use immunosuppressive medications in post liver transplant surgery but in lower doses…

    The body is similar to a soldier; it is programmed to recognize any threats to itself in order to defend itself from these things. Skin surrounds the body like a shield of armor, preventing anything unwanted from entering. What does manage to infiltrate the body will be examined by the immune system, then determined to be an ally or enemy. When a breach of security is detected, weapons are at the body’s disposal like any soldier. Cells, antibodies, macrophages and lymphocytes are simply a preview to the large arsenal the body contains. If recognized as a threat, the body will do anything in its power to destroy this substance and protect itself. Unfortunately for organ transplant recipients, transplants also fall into the category of a potential threat to the body. Transplants will trigger a natural response from the immune system to eliminate or neutralize the graft, a process known as rejection (Hoffman, Nelson, Drangstveit, Flynn,…

    All clinicians should have a good transplant immunology background so as to be more efficient and able to make better alternation in patients’ therapy if needed. Clinicians play an important role in explaining to patients the novel risk assessment and the treatment strategies and ongoing clinical trials they will go through (Heeger P.S. and Dinavahi MD.R, 2012). Human immune system is divided into innate and adaptive. Innate immunity is rapid but with no memory and little specificity. Innate immunity surrounds cellular components (eg. dentritic cells- DCs and natural killer cells -NKCs) and molecular components (eg. toll-like receptors- TLRs). Microbial products or endogenous pro-inflammatory ligands are released during the mechanical and ischemia-reperfusion injury (Ischemia-reperfusion is an injury observed when blood supply returns to tissue after ischemia period or reduced amount of oxygen and nutrients resulting in tissue damage) activating the innate immunity to…
