antigenic

having the properties of an antigen.

antigenic competition
the immune response to an antigen may be reduced if an unrelated antigen is administered simultaneously or shortly before. These may be between different molecules (intermolecular) or different determinants on the same molecule (intramolecular).
antigenic drift
point mutations in genes resulting in antigenic change. See also orthomyxoviridae.
antigenic mimicry
similarities between sequences found in microbial proteins and host proteins which may result in cross-reacting immune responses and autoimmune disease.
antigenic shift
genetic reassortment between two subtypes of a viral species resulting in a new subtype with completely different antigenicity. See also orthomyxoviridae.

Continued surveillance is recommended to monitor the distribution and the genomic and antigenic diversities of IAVs in feral swine to better assess the risk.
Previously, antigenic variation had been noted, but never had it been of a sufficient degree to compromise vaccine-induced immunity (24).
Taken together with the observation that the degree of antigenic change (drift, shift) is a major determinant of epidemic severity, little evidence exists for a substantial protective role of subtype cross-reactive memory Tc cells in human influenza virus infection; the contribution of Tc cells per se in the control of the infection is not questioned, only whether memory Tc cells provide a further improvement.

Minister for Agriculture and Minister for Land and Water Conservation (Syndey, Great Britain) has patented a method is provided of producing an immunogenic complex comprising a heat shock protein (hsp) coupled to a heterologous antigenic polypeptide, which method comprises: (a) expressing the antigenic polypeptide in a cell which cell has been subjected to a stimulus which causes the induction of a heat shock response in said cells; and (b) recovering the antigenic polypeptide coupled to one or more hsps from said cell or the culture medium.
