alloantigens

Example:The patient's immune system mounted a strong alloantigen response after the organ transplant.

Definition:The immune reaction triggered by the detection of alloantigens in a transplant or transfusion setting.

Example:The alloantigen antibodies were detected in the patient's serum after the blood transfusion.

Definition:Antibodies produced by the immune system in response to alloantigens, often leading to antigen-antibody reactions.

Example:The transplantation was delayed due to an alloantigen mismatch detected between the donor and recipient.

Definition:A situation where there is a discrepancy in the presence of alloantigens between donor and recipient in a transplantation or transfusion.

Example:Ensuring alloantigen compatibility is crucial for the success of a kidney transplant.

Definition:The level of similarity in alloantigens between donor and recipient, which affects the success rate of a transplantation or transfusion.

Example:The blood sample underwent alloantigen typing to identify potential donor matches.

Definition:The process of identifying the presence of specific alloantigens in an individual, used in transplantation and immunohematology.

Example:The alloantigen crossmatch was negative, indicating no significant immune reaction to the donor's organs.

Definition:A test performed to determine whether a potential recipient's immune system will react to a potential donor's alloantigens in a transplantation or transfusion.

Example:The blood donor was identified as an alloantigen donor based on tissue typing.

Definition:An individual who is a source of alloantigens for a transplant or transfusion, whose tissue is not genetically identical to the recipient.

Example:The immune system’s alloantigen recognition is the first step in mounting an immune response.

Definition:The process by which the immune system identifies and binds to alloantigens as foreign and potentially harmful.

Example:The patient’s alloantigen-based immunity developed over time, providing protection against infection.

Definition:Immunity that develops in response to the detection and challenge of alloantigens.

Example:The patient experienced alloantigen mediated rejection of the heart transplant, necessitating further immunosuppression.

Definition:A process where the recipient's immune system rejects transplanted organs or transfused blood due to the presence of alloantigens.
