HLA antigens (of which there are many types) are one of many antigen types with
which matching is attempted. There are many cell surface antigens which are of concern in organ matching. And of each antigen type, there are often multiple different
subtypes. Thus 'identical' matches are very rare. One exception is between identical
twins, one of which is the donor, and the other is the recipient. Because of difficulty in
obtaining 'perfect' matches, organ recipients generally must take immunosuppressive
medications long term. These prevent their own immune system from 'attacking' the transplanted organ, causing rejection. Non-the-less, they are not always effective.
However, with good medical care by docs versed in organ transplantation, rejection
can often be prevented.
HLA = Human Leukocyte Antigen ; important not only in transplantation, but also in
autoimmune diseases, i.e. SLE (lupus), rheumatoid arthritis, ankylosing
spondylitis, many others
One example : HLA B27 (assoc with ankylosing spondylitis)
Antigens are proteins which are attached to the cell surface, thus are available for
detection by immune cells, antibodies, and other immune mediators

What cell componants have to match for an organ transplant?
For an organ transplant to be successful, the recipient's human leukocyte antigens (HLAs) must match as closely as possible with those of the donor's cells. In addition to HLAs, blood type compatibility is also crucial for a successful organ transplant.
What is the significance of blood type in determining compatibility for organ transplants?
Blood type is significant in determining compatibility for organ transplants because the recipient's immune system can reject an organ if the blood types of the donor and recipient are not compatible. Matching blood types helps reduce the risk of rejection and increases the chances of a successful transplant.
Does an organ transplant alter your DNA?
No, an organ transplant does not alter your DNA. The transplanted organ retains its original DNA, while the recipient's DNA remains unchanged.
Someone who recieves an organ or tissue?
A person who receives an organ or tissue is referred to as a transplant recipient. This individual undergoes surgery to have the donated organ or tissue transplanted into their body to replace a damaged or failing organ. Following the transplant, recipients require ongoing medical care and may need to take immunosuppressant medications to prevent rejection of the transplant.
What is the difference between organ transplant and artificial organs?
An organ transplant is when organs are taken out of human organ donors and placed into another human, but artificial organs are either grown in science labs from stem cells or electronic organs that are usually made of plastic or metal.
What cell componants have to match for an organ transplant?
For an organ transplant to be successful, the recipient's human leukocyte antigens (HLAs) must match as closely as possible with those of the donor's cells. In addition to HLAs, blood type compatibility is also crucial for a successful organ transplant.
What is the purpose of a organ transplant?
Answer: The purpose of an organ transplant is to replace any vital organ not functioning and help revive (partial transplant)/make survival possible by donor organ.
Who are not good candidates for a pancreas transplant?
Many people with diabetes are not good candidates for a pancreas transplant. Others do not have tissue compatibility with the donor organ. People who are successfully controlling their diabetes with insulin injections are usually not considered.
What is the significance of blood type in determining compatibility for organ transplants?
Blood type is significant in determining compatibility for organ transplants because the recipient's immune system can reject an organ if the blood types of the donor and recipient are not compatible. Matching blood types helps reduce the risk of rejection and increases the chances of a successful transplant.
What factors are considered in organ matching?
Factors considered in organ matching include blood type, tissue compatibility, organ size, medical urgency of the recipient, distance between donor and recipient, and waiting time on the transplant list. These factors are taken into account to ensure the best possible match and increase the likelihood of a successful transplant.
Are you against or for organ transplant?
are you against or for organ transplant cause i wanna know its for a science project
What is an organ transplant?
It is when a major organ is removed from the body and a replacement fitted or transplanted. Such as a heart transplant.
How do you find out if you are registered for organ transplant?
To find out if you are on the waiting list for an organ transplant, talk to the transplant coordinator at the hospital that your are registered with. If you wish to find out if you are a registered organ donor (in the UK), look at www.organdonation.nhs.uk/
What caused the first organ transplant?
Organ failure.
What is rejection of organ transplant called?
organ rejection
When an organ transplant is not accepted by an individual?
It results in "organ rejection".
Does an organ transplant alter your DNA?
No, an organ transplant does not alter your DNA. The transplanted organ retains its original DNA, while the recipient's DNA remains unchanged.
