| HLA-dp antigens | <immunology> A group of the d-related HLA antigens (human) found to differ from the dr antigens in genetic locus and therefore inheritance. These antigens are polymorphic glycoproteins comprising alpha and beta chains and are found on lymphoid and other cells, often associated with certain diseases. (12 Dec 1998) |

| HLA-dq antigens | <immunology> A group of the d-related HLA antigens found to differ from the dr antigens in genetic locus and therefore inheritance. These antigens are polymorphic glycoproteins comprising alpha and beta chains and are found on lymphoid and other cells, often associated with certain diseases. (12 Dec 1998) |
| HLA-dr antigens | <immunology> A group of d-related human leukocyte antigens that are polymorphic glycoproteins found on lymphoid cells. They consist of alpha and beta chains and their inheritance differs from that of the dq and dp antigens; their presence seems to be associated with certain skin diseases like pemphigus vulgaris, dermatitis herpetiformis, and type I diabetes. (12 Dec 1998) |
| HTLV-blv antigens | Antigens associated with the HTLV-blv viruses. Htlv-I antigens and HTLV-II antigens belong to this group. (12 Dec 1998) |
| HTLV-I antigens | Antigens associated with the HTLV-I virus. (12 Dec 1998) |
| HTLV-II antigens | Antigens associated with the HTLV-II virus. (12 Dec 1998) |

| human leukaemia-associated antigens | Antigen's on the surface of leukaemic cells which seem not to be present on the surfaces of the same type of normal cells; the myeloblast antigen of acute myelogenous leukaemia found in chronic myelogenous leukaemia is thought to be associated with a "blastic" transformation. (05 Mar 2000) |
| human leukocyte-associated antigens | Proteins on the outer part of body cells that help fight illness. These proteins vary from person to person. Scientists think that people with certain types of HLA antigens are more likely to develop insulin-dependent diabetes.The HLA antigens are also responsible for histocompatibility reactions. (09 Oct 1997) |
| specific antigens | Antigen's that characterise a single genus of microorganisms. (05 Mar 2000) |
| I antigens | A blood group related both to the abo and p systems that includes several different antigens found in most people on erythrocytes, in milk, and in saliva. The antibodies react only at low temperatures. (12 Dec 1998) |
| I region associated antigens | Class II major histocompatibility (MHC) antigens. (18 Nov 1997) |
| O antigens | Tetra and penta saccharide repeat units of the cell walls of gram-negative bacteria. They are a component of lipopolysaccharide. (18 Nov 1997) |
| oncofetal antigens | Tumour-associated antigen's present in foetal tissue but not in normal adult tissue, including alpha-fetoprotein and carcinoembryonic antigen. (05 Mar 2000) |
| T antigens | Tumour antigens associated wtih replication and transformation by certain DNA tumour viruses, including adenoviruses and papovaviruses. See: beta-haemolytic streptococci, tumour antigens. (05 Mar 2000) |
