How can tissue rejection be prevented?
tissue rejection will not be a problem if the tissue to be transplanted comes from the same person.
What does tissue rejection mean?
after a graft or transplant, the immune response of the recipient to foreign tissue cells, with production of antibodies and eventually destruction of the transplanted organ. acute rejection , acute cellular rejection , cellular rejection.
Which substances produced in the body are directly responsible for rejection of a transplanted organ?
T cells and antibodies are two primary substances produced by the body that are responsible for rejection of a transplanted organ. T cells recognize the transplanted organ as foreign and mount an immune response, while antibodies can target the transplanted tissue for destruction. These responses can lead to rejection if not controlled by immunosuppressive medications.
Can you donate your eyes?
The cornea. Interestingly it is avascular and so can generally be transplanted without regard to tissue typing and without immunosupressants.
How does tissue damage occur in acute rejection after an organ transplant?
Tissue damage during acute rejection after an organ transplant primarily occurs due to an immune response initiated by the recipient's body recognizing the transplanted organ as foreign. This immune response is mediated by T cells that infiltrate the transplanted tissue, leading to inflammation and destruction of donor cells. Additionally, antibodies may be produced that target donor antigens, further contributing to tissue injury. The result is acute inflammation and damage to the transplanted organ, which can impair its function.
What is the only tissue that can be transplanted from one person to another with little or no rejection in the retna of the eye?
The only tissue that can be transplanted from one person to another with minimal rejection in the retina of the eye is the retinal pigment epithelium (RPE). This is primarily due to the immune privilege of the eye, which reduces the likelihood of rejection compared to other tissues. The RPE plays a critical role in supporting photoreceptors, making it a valuable target for transplantation in retinal diseases.
What is immuno-suppressants?
tissue transplanted from part of the body to part of your genital area.

A common occurrence in transplant patients in which the patient's immune system attacks the donated organ or tissue?
This is known as organ rejection, where the recipient's immune system recognizes the transplanted organ as foreign and mounts an immune response against it. To prevent rejection, transplant patients are typically prescribed immunosuppressive medications to dampen their immune response and protect the transplanted organ. Regular monitoring and adjustment of these medications are essential to prevent rejection.
How might organs transplants which are meant to save a person life endanger the person?
An organ transplant can cause tissue rejection, where the patient's immune system tries to destroy the transplanted organ, because the foreign organ is mistaken for pathogens.
Why do killer cells cause rejection of an organ transplant?
Killer cells, specifically cytotoxic T cells, can cause rejection of an organ transplant because they recognize the transplanted tissue as foreign due to differences in major histocompatibility complex (MHC) molecules. When T cells identify these foreign antigens, they become activated and initiate an immune response, leading to the destruction of the transplanted cells. This rejection process is a natural defense mechanism of the immune system to protect the body from perceived threats. Immunosuppressive medications are often used to mitigate this response and promote transplant acceptance.
Is the cornea a living tissue?
No, the cornea is a transparent, avascular tissue that lacks blood vessels and nerves. It is composed of specialized cells called keratocytes that help maintain its structure and transparency.
