background: in some studies inflammatory bowel disease (ibd) and celiac disease were considered to be associated and some belive that this association may influence the prognosis of ibd. however, there is a cosiderable controversy regarding this association. therefore ,we aimed to assess the association of these two common digestive diseases and evaluate the complications of this association. m...
Background: Our previous predictive peptide binding studies indicated that a novel 20-mer multiple antigen peptide, CH401MAP, containing an anti-human epidermal growth factor receptor 2 (HER2) monoclonal antibody epitope (N163-182), may potentially bind to more than 95% of class I human leukocyte antigens (HLAs) and to 30-50% of class II HLAs expressed on peripheral blood mononuclear cells (PBM...
Antibodies to a capsular polysaccharide (PS) provide protection against Streptococcus pneumoniae which express the homologous capsular serotype, and pneumococcal vaccines are designed to induce antibodies in the capsular PS. Levels and opsonophagocytic capacity of antibodies to the capsular PS of S. pneumoniae serotype 19F were determined by sera from adults immunized with 23-valent S. pneumoni...
In previous experimental animal studies it has been demonstrated that antibody depletion is not followed by increased antibody synthesis. To assess whether these results are conferrable to antibody-depleted humans, we measured free light chains (flcs) as markers of current antibody synthesis in 8 patients treated with immunoadsorption (IA) therapy. Specific and bulk immunoglobulin levels were o...
Heterogeneity with regard to affinity of anti-hapten antibody was demonstrated at the cellular level in mice. The heterogeneity was shown at the level of single antibody-forming cells using hapten inhibition of hemolytic antibody plaque formation as a measure of affinity. The affinity increased with time after immunization. A high antigen dose initially resulted in relatively low affinity antib...

This study assessed the level of vaccine-induced hepatitis B surface antibody that is protective against hepatitis B infection and carriage in The Gambia. Sera from 700 of a cohort of 1041 children vaccinated against hepatitis B in infancy were serially tested for markers of hepatitis B until age 7 years. No absolute level of protection against infection was found, but all children who attained...
There are no contemporary data available describing human immunity to novel influenza A/H7N9. Using 1723 prospectively collected serum samples in southern Vietnam, we tested for antibodies to 5 avian influenza virus antigens, using a protein microarray. General-population antibody titers against subtype H7 virus are higher than antibody titers against subtype H5 and lower than titers against H9...
One of the most used ancillary techniques by surgical pathologists in clinical practice is immunohistochemistry (IHC) that, through an antibody–antigen reaction, allows for detection specific proteins at cellular level [...]
