Alloantibodies are antibodies that are produced by the immune system in response to foreign antigens found on the surface of cells or tissues from a different individual of the same species. The presence of alloantibodies can lead to an immune response that can cause tissue damage, rejection of transplanted organs, and other medical complications.
Definitions
Alloantibodies are antibodies that are produced by an individual’s immune system in response to foreign antigens found on the surface of cells or tissues from another individual of the same species. These antibodies can cause an immune response that can lead to tissue damage, rejection of transplanted organs, and other medical complications.
Origin
The term “alloantibody” is derived from the Greek words “allo-” meaning “different” and “antibody” meaning “a protein produced by the immune system in response to a foreign substance”. Alloantibodies are produced when an individual’s immune system recognizes foreign antigens on the surface of cells or tissues from another individual of the same species.
Meaning in different dictionaries
According to the Merriam-Webster dictionary, alloantibody is defined as “an antibody that is produced by an individual in response to antigens from another individual of the same species”. The Oxford English Dictionary defines alloantibody as “an antibody that is produced by the immune system in response to foreign antigens found on the surface of cells or tissues from another individual of the same species”.
Associations
Alloantibodies are associated with a variety of medical conditions, including blood transfusion reactions, hemolytic disease of the newborn, and transplant rejection. In blood transfusion reactions, alloantibodies can cause the destruction of red blood cells, leading to anemia and other complications. In hemolytic disease of the newborn, alloantibodies produced by the mother can cross the placenta and attack the red blood cells of the fetus, leading to anemia and other complications. In transplant rejection, alloantibodies can cause the rejection of transplanted organs by attacking the foreign antigens on the surface of the transplanted tissue.
Synonyms
Synonyms of alloantibody include isoantibody, heteroantibody, and allospecific antibody.
Antonyms
Antonyms of alloantibody include autologous antibody, which is an antibody that is produced by an individual’s immune system in response to antigens found on their own cells or tissues.
The same root words
The same root words as alloantibody include alloantigen, which is a foreign antigen found on the surface of cells or tissues from another individual of the same species, and alloimmunity, which is an immune response to foreign antigens found on the surface of cells or tissues from another individual of the same species.
