1. Antibody immunity uses B cells to secrete antibodies. The antibodies are circulated through the plasma cells in the body and bind to the transplant. They then attack the transplant because they see it as a foreign body. Cell-mediated immunity also works to attack the "foreign body" but is uses T cells that are directly attached to the transplant. This eliminates the infected cell" before it has time to multiply. (Alberts, B. 1970)

2. Your immune system is constantly working to fight off foreign invaders. The body recognizes its own cells from foreign cells by protein markers or antigens. As the B and T cells form the can tell the difference between your own cells and foreign cells. B and T cells help form a memory for your immune system. …show more content…

An Autograft is a graft taken from one part of the patients own body and placed on the part of the body needing a graft. There is no risk of rejection with an Autograft because the cells are your own and not seen as a foreign object. An Allograft is a graft from a cadaver a donor from the same species that is harvested in a tissue bank. When using this graft the patients immune system must be suppressed to further prevent rejection of the transplant. Allograft. …show more content…

A skin cell gun uses the patients own skin cells mixed with a water base solution. This is very interesting because it remind me of a paint gun. The mixture is sprayed onto the burned area instead of using a graft. Bachai, S. (2014, April 09) To me this is extremely helpful for second and third degree burns because it seems easier to apply than a graft, much less maintenance, no rejection because it is your own stem cells, and the healing time is much faster.

5. Scientist are working on a way to end the need for organ transplant all together. They are using gene therapy to generate stem cells at the site of the damaged organ. This would use the patients stem cells to regenerate the organ while still in the body. It is currently only being tested on mice. Connor, S. (2013)

6. I think the fact that a patient can use their own stem cells to heal is an amazing concept. It makes for a faster healing process, much less treatment than all the follow ups that are needed for grafting, and possibly less painful. If I needed this treatment I would definitely consider using stem

An organ transplant is an operation that places a healthy organ from one person into another. The organ can come from someone who has died (a deceased donor) and has signed their state’s donor registry or told their family of their wishes to become a donor. Up to 25 different organs can be donated for transplantation. Transplantable organs include the heart, kidneys, liver, lungs, pancreas, and small intestines. According to Donate Life America's 2011 statistics, there were 8,127 deceased organ donors and 6,017 living organ donors in the United States, adding up to 28,535 organ transplants overall.

Nevertheless, this chapter did an exceptional job of explaining the function of the immune system as well as the effect of HIV on the immune system. The immune system has two main functions; to limit the amount of virus made then to clear the virus from the host. This process starts with the crucial ability to discriminate between foreign antigens and the body’s own proteins which is allows the immune system to only attack the virus that has infected the body. Initially upon infection, the immune system responds quickly in ways nonspecific to the particular virus at hand, employing natural killer lymphoid cells and phagocytic macrophages to surround then engulf the virus as well as proteins called complement factors that

Zoe Imagine being on a national organ transplant list and have been given a choice. Do you want a human organ or an animal organ? Yes, Xenotransplantation is a large medical breakthrough, but it come with a tremendous amount of risk involved. Animal organs are not meant to be in a humans body. Therefore, human organs should be used for people on the donation list instead of Xenotransplantation.

Doctors would then have to inject the body with immunosuppressive drugs, and the recipients would most likely have to take these drugs for the rest of their life, costing them hundreds of dollars (Joo, Kim, Kang, and Lee, 2010). In the end, my opinion on the subject has changed since I first began my research. I am now against the testing and research of Xenotransplantation, and would rather have scientists and doctors focus on ways on how to use human cells as a solution to the organ shortage, as I had mentioned in my personal

I both agree and disagree. I agree because xenotransplant is another way that we can aid people to live another day, where they don 't have to suffer in pain or struggle with day to day activities. It gives them a chance to enjoy life 's opportunities before it is too late. On the other hand, I also disagree because there are many risks that can take place, and not just to the recipient of the organ or tissues, but also to the people around them. So by trying to save one person, one ends up killing much more.

In the short term, demand of transplants can be met (Groth et al., 2000; Fix, n.d.; Cooper, 2015), which would reduce the number of patients on waiting lists for transplants. Using cross species transplantation can improve the quality of life that some people have. While transplants may not be flawless, as mentioned later in this article, they can ‘buy time’ for patients on waiting lists (The National Health and Medical Research Council, 2003). This can give people who may otherwise lose their life some time to enjoy things and fulfil their dreams or enjoy their final moments. Although this does not appear to be impressive to those of us with greater health, for the less fortunate it means everything (Groth et al.,

Vaccines work by building your immune system against future attacks by infections or diseases. When a pathogen enters your body, your immune system creates what is called antibodies to fight them off. Vaccines are created as a immune response that will protect the individual during the time of exposure to a infection or disease. In

Organ transplantation is an important process in which a functioning organ is donated for someone with an organ that no longer functions properly. It is a life-changing process that takes time and caution to be done properly. Even after the surgery, those who receive the organ must take care of their newly-acquired gift. Nonetheless, the breakthroughs from this process have opened doors to new lives.

We are moving into an era of “tissue economies”: the transfer and circulation of human tissue on a global scale (Waldby and Mitchell 2006). This includes the donation of, and trade in, sperms and ova, as well as the in vitro fertilization and implantation of embryos, and, in some cases, the rental of uteruses for these embryos to grow in (surrogate motherhood). Tissue engineering (growing organs from stem cells cultivated in the laboratory) is a technology which might become a reality in the future. But considering the case of xenotransplantation (using genetically modified animals to harvest organs for humans), a technology which looked very promising 20years ago but came to a total halt because of the risks of zoonosis (transfer of viruses between species), one should be careful when assessing what clinical options organ engineering in the laboratory will be able to provide (Sharp 2007). There are three metaphors that guide contemporary thinking about organ, tissue, and cell transplantation as

The surgical removal of an organ or tissue from one person and placing it into another person. That is the definition of organ transplantation, one of the most important surgical procedures to date. It is necessary for human life to be sustained in today’s world. The need for organs continues to grow, however, the supply does not grow with it. Whether it be because there are more irritants to cause organ failure, or a lack of donors, it’s hard to tell which may be impacting more.

Introduction: Organ transplantation is a relatively new field of interest in medicine and it is only over the past century that many breakthroughs in organ transplantation have been made (). Organ transplantation has enabled people who have been diagnosed with organ failure and have an increasingly degenerating bodily component (organ) to regain the functionality of their body by having another person’s organ implanted into them (Waldby C. 2002. Page 239), offering the potential to enhance and save a life (Haddow G. 2005, pg 92). This incorporation of an outer body component into the organ receiver’s body is not simply a biomedical issue, involving biological factors and medical procedures performed in an often surgical fashion, but also a

We are a big nation of over 1.2 billion people and it is a disappointing fact that only 0.08% per million people, which is extremely low, could be called as organ donors. There is a dire need in raising this figure and it is high time we step up our efforts in promoting Organ Donation. I think the first initiative should come from doctors as it is they who know if an organ donation is possible when a person dies. For example, an accident casualty can become a heart donor or a person who dies of a cardiac failure can become a donor of other organs and tissues like liver, bone, eyes, skin, etc. Also, when a doctor realises that a patient’s chances of survival are less than a year regardless of medical treatment, he should suggest the ‘noble cause’ with the patient and his or her family.
