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

Viruses Virtues And History Chapter 3 Summary

602 Words | 3 Pages

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.

The lymphatic system through its components, such as lymph, lymph nodes and lymph vessels is used to defend the body against diseases and infections, and to transfer lymph between the blood streams and tissues (Gold, 2004).

The immune system comprises of complex levels of protection for the body including the blood and lymph

Organ Donation Research Paper

869 Words | 4 Pages

Organ transplantation provides a life-saving opportunity for those who have no other options. Men, women, and children of all ages, all ethnicities, and all walks of life have had organ transplants. The first successful transplant was performed between identical twins in Boston’s Brigham and Women’s Hospital in 1954. Since the beginning of national data collection in 1988, more than 560,000 transplants have been performed in the U.S. and success rates of recipients have continued to increase in number of years lived post-transplant, with many surviving 25 years and more. Unfortunately, organ transplantation cannot be made available to all who need it because there are not enough donors to meet the ever-increasing need for organ transplantation.

The Pros And Cons Of Xenotransplantation

811 Words | 4 Pages

Scientists all around the world are now considering Xenotransplantation as there are very few human tissue and organs available. Causing many patients who desperately need replacement organs to wait for a suitable donor. The average median waiting time for an organ transplant ranges from approximately 4 months (heart or lung transplant) up to 5 years (kidney transplant). This clearly poses an issue to patients in desperate need of a transplant, as it is likely they are unable to wait that period of time to find

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.

The Adaptive Immune System

788 Words | 4 Pages

Both defence mechanism of the immune system have ability to distinguish between self and non-self molecules. In immunology, self molecules are those components of an organism’s body that can be distinguished from foreign substances by the immune system (102), while non-self of molecules are those that are recognized as foreign molecules. One class of non-self molecules are called antigens and are defined as substances that bind to specific immune receptors and elicit an immune response(102).Non-specific defence mechanism is known as innate immune system, meaning these systems respond to pathogens in a generic way(99). No immunological memory is developed during innate immune response. The innate immune system is the dominant system of host defence in most organisms.

Organ Donation Benefits

1396 Words | 6 Pages

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.

Cytokines Research Paper

1593 Words | 7 Pages

Although these other two terms continue to be used, they are misleading because secretion of many lymphokines and monokines is not limited to lymphocytes and monocytes as these terms imply, but extends to a broad spectrum of cells and types. For this reason, the more inclusive term cytokine is preferred. Many cytokines are referred to as interleukins, a name indicating that they are secreted by some leukocytes and act upon other leukocytes. Interleukins 1–25 have been identified. There is reason to suppose that still other cytokines will be discovered and that the interleukin group will expand further.
