T Cell Mediated Rejection

T cell mediated rejection is a process where the immune system attacks transplanted tissues or organs, perceiving them as foreign. T cells, a type of white blood cell, recognize the new organ's cells as different due to their unique proteins. This triggers an immune response, leading to inflammation and damage to the transplanted organ. This type of rejection can occur days to months after the transplant, and it is a major challenge in organ transplantation. To prevent this, patients are often given immunosuppressive medications to help the body accept the new organ and minimize the immune response.
