An immunological response to incompatibility in transplanted tissues and organs mediated by both cellular and humoral immunity; may lead to destruction of the transplanted tissue or organ.
In immunology, an immune response that causes transplanted organs or tissues to be attacked by the immune system of the body and to destroy the transplanted organ or tissue.
The act of rejecting tissue.
In relation to a transplant, the attacking of the donated organ or tissue by the body’s immune system; more widely, it may refer to instances where one or both parents fail to fully accept their roles as parents of a child, often leading to lack of bonding and maternal deprivation syndrome or failure to thrive.
In medicine, immunological response whereby substances or organisms that the system recognizes as foreign are not accepted, as in the body’s attack against invading micro-organisms (e.g., bacteria) or rejection of a transplanted organ.
A term used in transplant medicine to describe the body’s immunological response to foreign tissue. Various drugs, such as ciclosporin A, can be used to dampen the host’s response to a graft or organ transplant and reduce the risk of rejection.
Refusal to accept or to show affection. In animals, for example, the young may be ignored or driven away by their mother.
The phenomenon where the immune system launches an assault on foreign tissue, such as an organ that has been transplanted, is referred to as graft rejection.
An immune response targeted at eliminating organisms or substances identified as foreign by the body’s immune system. Rejection also pertains to the refusal of acceptance regarding tissue grafts or organ transplants.
In order to prevent rejection, donor tissues are carefully matched with those of the recipients. Organ transplant recipients are administered immunosuppressant medications, including corticosteroids and ciclosporin, to dampen the immune system’s response and thus suppress rejection.
