introduction: vaccinology provides promising approaches for the control of various infectious diseases. among different strategies, dna vaccines offer attractive research opportunities for development of vaccines for induction of antigen-specific immunity owing to their stability, simplicity of delivery, safety and cost effectiveness. however, there is a need to increase their potency by the us...

Certain carbohydrates (rhamnose, 3-O-methyl rhamnose, and galactosamine) have been demonstrated to be present in Bacillus anthracis spores but absent in vegetative cells. Others have demonstrated that these spore-specific sugars are constituents of the glycoprotein BclA. In the current work, spore extracts were separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. A second col...

Cells expressing the spike (S) glycoprotein of the neurotropic JHM strain (JHMV) of mouse hepatitis virus (MHV) are susceptible to lysis by B cells derived from naïve mice, including B cells from perforin-deficient mice. Cytolysis requires interaction of the virus receptor and the viral S glycoprotein, is independent of other viral-induced components, and is not a unique property of B cells. Ne...

Duffy was the first blood group mapped to an autosome (chromosome 1) using cytogenetic studies. Duffy antigens are located on a glycoprotein that can be found on erythrocytes and other cells throughout the body. Fy(a) and Fy(b) are products of their respective alleles (FY*A, FY*B). Fy(x) characterized by weak Fy(b) expression, is a result of an additional mutation in FY*B. The Fy(a-b-) phenotyp...

The principal components of a variety of mucous secretions have been found to be glycoproteins, many of mol.wt. 500000 or more (Gottschalk, 1972). We have isolated the glycoprotein from pig colonic mucus and examined its structure in order to compare it with that of the well-characterized glycoprotein of the gastric mucus from the same species (Snary & Allen, 1971 ; Allen, 1977). Mucosal scrapi...
