Since Nagler's discovery" of the hemagglutinin obtained from suspensions of vaccinial lesions on the chorio-allantois, a number of investigators have attempted to characterize it more precisely. Nagler"" and others'"" have shown that antibodies which inhibit vaccinia hemagglutinin (V.H.) develop in man, rabbits, mice, and guinea pigs following infection with vaccinia virus, but it is not known ...
We earlier suggested that type A human influenza virus genes undergo positive Darwinian selection through immune surveillance. This requires more favorable amino acid replacements fixed in antigenic sites among the surviving lineages than among the extinct lineages. We now show that viral hemagglutinins fix proportionately more amino acid replacements in antigenic sites in the trunk of the evol...
Background Marine sponges are a rich source of novel biologically active substances such as haemolytic proteins, hemagglutinins and proteins with antimicrobial, antiviral and antifungal activity. Toxic water-soluble polymeric 3alkylpyridinum salts (poly-APS) have been isolated from the marine sponge Reniera sarai. Poly-APS has pore-forming properties expressed in a dose-dependent manner. These ...
The hemagglutinins (HAs) of human H1 and H3 influenza viruses and avian H5 influenza virus were produced as recombinant fusion proteins with the human immunoglobulin Fc domain. Recombinant HA-human immunoglobulin Fc domain (HA-HuFc) proteins were secreted from baculovirus-infected insect cells as glycosylated oligomer HAs of the anticipated molecular mass, agglutinated red blood cells, were pur...
More than 120 years ago, Peter Hermann Stillmark in his doctoral thesis presented in 1888 to the University of Dorpat, gave the earliest step in the study of proteins that have a very interesting feature: the ability to agglutinate erythrocytes. These proteins were initially referred as to hemagglutinins or phytoagglutinins, since they were originally isolated from extracts of plants [1]. The f...
