Isoantigens |
Antigens that exist in alternative (allelic) forms in a single species. When an isoantigen is encountered by species members who lack it, an immune response is induced. Typical isoantigens are the BLOOD GROUP ANTIGENS. |

Lewis Blood Group Antigens |
Carbohydrate antigens structurally related to the ABH BLOOD-GROUP SYSTEM. They may occur as a modification of saccharide chains on glycolipids or glycoproteins on cell surfaces or in plasma, or as free oligosaccharides in secretions. Lewis antigens are not synthesized in blood cells. Instead Lewis glycolipids present in plasma are absorbed onto the surface of ERYTHROCYTES; LYMPHOCYTES; and PLATELETS. The phenotypes Le(a) and Le(b) are the result of the actions of two genes the Le gene (fucosyltransferase FUT3) and the Se gene (fucosyltransferase FUT2) on the precursor carbohydrate, glycolipid or glycoprotein. Other FUCOSYLTRANSFERASES can also synthesize the Lewis antigens. |

ABO Blood-Group System |
The major human blood type system which depends on the presence or absence of two antigens A and B. Type O occurs when neither A nor B is present and AB when both are present. A and B are genetic factors that determine the presence of enzymes for the synthesis of certain glycoproteins mainly in the red cell membrane. |

Stomatitis, Aphthous |
A recurrent disease of the oral mucosa of unknown etiology. It is characterized by small white ulcerative lesions, single or multiple, round or oval. Two to eight crops of lesions occur per year, lasting for 7 to 14 days and then heal without scarring. (From Jablonski's Dictionary of Dentistry, 1992, p742) |
