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.
An autologous transplant is a type of transplant that uses the patient's own tissue or cells. This type of transplant is typically used in procedures such as bone marrow or stem cell transplants. Autologous transplants reduce the risk of rejection since the tissue or cells are from the patient's own body.
cells with protein markers do not interact with white blood cells' receptor molecules and are not detected by the immune system.
Major histocompatibility complex (MHC) proteins, specifically MHC class I and II, are responsible for initiating an immune response against foreign tissues in tissue transplants. These proteins present antigens to T cells, triggering the immune system to recognize and reject the transplant as a foreign entity.
The main advantage of this new method is that it uses stem cells to generate pancreatic cells, eliminating the need for donor organs. This reduces the risk of rejection and the need for immunosuppressive drugs, making the procedure safer and more accessible for patients.
By producing human antigens on their cell surfaces, the genetically modified pigs can effectively disguise themselves as human cells to the recipient's immune system, reducing the chances of rejection. This helps to minimize the immune response and improve the compatibility between the donor organ and the recipient's body.
Killer t cells are activated by helper t cells. The Helper t cells are alerted by the macrophage that has engulfed the virus. It grows antigens to alert the helper t cells. The killer t cells are like white blood cells, there purpose is to fight pathogens.
T-cells B-cells NK cells (natural killer)
The thymus produces both helper t and killer t cells in the fight against infection. The killer t cells eliminate harmful cells and organic materials from the bloodstream
Organ transplant involves replacing a damaged or failing organ with a healthy organ from a donor. Artificial organs are man-made devices designed to perform specific functions of a natural organ, providing temporary or permanent support. Organ transplant carries the risk of rejection and requires a donor match, while artificial organs minimize the risk of rejection but may not replicate the full function of a biological organ.
