Continued surveillance is recommended to monitor the distribution and the genomic and antigenic
diversities of IAVs in feral swine to better assess the risk.
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.
An intriguing hypothesis is that particular antigenic
variants of the spirochete may be associated with life in an arthropod vector (usually ticks, except for the related spirochete, B.
The patent contains additional claims to methods of treating infectious diseases with HSP-peptide complexes purified from pathogen-infected cells, an approach Antigenics
is testing in preclinical models of herpes simplex virus type-2, the causative agent of genital herpes.
One of the Ii fragments, called 'Ii-Key,' acts on a regulatory site on the MHC class II molecule and controls the association of that molecule with antigenic
classification of registered arboviruses I.
The Antigen Express technology induces special receptors for endogenous tumor antigenic
peptides, the Major Histocompatibility Complex class II molecules, in the absence of the immunoregulatory Ii protein.
Does glycosylation as a modifier of original antigenic
sin explain the case age distribution and unusual toxicity in pandemic novel H1N1 influenza?
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.

It is believed that pigeon droppings samples contain antigenic
material derived from IgA in pigeon serum, pigeon-excreta material, fragmented feathers, waxing substance coating the feathers, and intestinal mucin (1,7-10).
