| antigenic | Having the properties of an antigen (allergen). Synonym: allergenic, immunogenic. (05 Mar 2000) |
|---|---|
| antigenic competition | Competition that occurs when two different antigens, each of which can evoke an immunological response when inoculated alone, are mixed in equal quantities and inoculated together; the response may be to only one, that to the other being largely or entirely suppressed. (05 Mar 2000) |
| antigenic complex | A composite of different antigenic structures, such as a cell or a bacterium, or, by extension, a molecule containing two or more determinant groups of different antigenic specificities. (05 Mar 2000) |
| antigenic determinant | That part of an antigenic molecule against which a particular immune response is directed. For instance a tetra to penta peptide sequence in a protein, a tri to penta glycoside sequence in a polysaccharide. In the animal most antigens will present several or even many antigenic determinants simultaneously. See: hapten. (18 Nov 1997) |
| antigenic drift | <immunology> A change that occurs on the molecular level to effect a change in the antigenicity of a bacteria or virus. Antigenic drift occurs naturally and more rapidly in certain viruses (for example HIV). It is antigenic drift which complicates the development of an effective HIV (AIDS) vaccine. (27 Sep 1997) |
| antigenic modulation | Loss of detectable antigen from the surface of a cell after incubation with antibodies. This is one method in which some tumours escape detection by the immune system. Antigenic modulation of target antigens also reduces the therapeutic effectiveness of treatment by monoclonal antibodies. (12 Dec 1998) |
| antigenic shift | Mutation, i.e., sudden change in molecular structure of RNA/DNA in microorganisms, especially viruses, which produces new strains of the microorganism; hosts previously exposed to other strains have little or no acquired immunity to the new strain; antigenic shift is believed to be the explanation for the occurrence of strains of microorganisms, such as the influenza virus, associated with large scale epidemics. (05 Mar 2000) |
| antigenic switching | <immunology> The process by which a pathogenic microbe's genetic structure is altered tochange its surface antigens inorder to avoid being detected by the host's immune system. (09 Oct 1997) |
| antigenic variation | The phenomenon of changes in surface antigens in parasitic populations of Trypanosoma and Plasmodium (and some other parasitic protozoa) in order to escape immunological defense mechanisms. at least 100 different surface proteins have been found to appear and disappear during antigenic variation in a clone of trypanosomes. Each antigen is encoded in a separate gene. Antigenic variation is also known to occur in free living Protozoa and certain bacteria. (18 Nov 1997) |
| idiotypic antigenic determinant | The antigenic specificites defined by the unique sequences (idiotopes) of the antigen combining site. Thus anti-idiotype antibodies combine with those specific sequences, may block immunological reactions and may resemble the epitope to which the first antibody reacts. (18 Nov 1997) |
| addition-deletion mutation | <molecular biology> A type of mutation that results from insertion or deletion of a single nucleotide into, or from, an open reading frame in the normal DNA sequence. Normally, the genetic code is read in the wrong frame, three nucleotides at a time, and the entire sequence downstream of the mutation, is translated into a polypeptide with a garbled amino acid sequence from the mutated codon onwards. These mutations may be induced by certain types of mutagens or may occur spontaneously and usually result in the generation, downstream, of nonsense, chain termination codons. Synonym: addition mutation, addition-deletion mutation, deletion mutation, reading-frameshift mutation. (21 Jun 2000) |
| gene deletion | The total loss (or absence) of a gene. Gene deletion plays a role in birth defects and in the development of cancer. (12 Dec 1998) |
| chromosomal deletion | A microscopically evident loss of part of a chromosome. See: monosomy. (05 Mar 2000) |
| chromosome deletion | Actual loss of a portion of the chromosome. (12 Dec 1998) |
| clonal deletion | The removal of B-cell and T-cell varieties which recognise parts of the organisms body as targets of the immune system. This process naturally occurs early in the organisms development so that the organism will not be autoimmune (having an immune reaction against one's own body tissues) later in life. (09 Oct 1997) |
