BACKGROUND The Plasmodium falciparum pre-erythrocytic stage candidate vaccine RTS,S is being developed for protection of young children against malaria in sub-Saharan Africa. RTS,S formulated with the liposome based adjuvant AS01(E) or the oil-in-water based adjuvant AS02(D) induces P. falciparum circumsporozoite (CSP) antigen-specific antibody and T cell responses which have been associated wi...
tropical fasciolosis caused by infection with fasciola gigantica is regarded as one of the most important single helminthes infections of ruminants in asia and africa. fasciolosis diagnosis, due to low sensitivity of coprological diagnostic method has been challenging for a long period. to evaluate the usefulness of elisa for diagnosis of anti – fasciola gigantica antibodies in parasitized shee...
Early lymphocyte development is characterized by the regulated activity of the V(D)J recombinase and the positive and negative selection of cells based on the structure of their assembled antigen receptor genes. Developing B and T cells use remarkably similar signaling complexes, the pre-B-cell receptor (pre-BCR) and the pre-T-cell receptor (pre-TCR) respectively, to monitor the progress of ant...
Background and Objective: Lipoarabinomannan mannesylated (ManLAm) is one of the lipoglycans which forms a considerable percent of Mycobacterium Bovis BCG’ cellular wall. Considering that generation of monoclonal antibody against ManLAM antigen has many applications, specifically, in order to design the diagnostic kit for rapid diagnosing of tuberculosis, so the main objective of this study wa...
Although the use of recombinant hepatitis B virus surface (HBsAg) protein vaccine has successfully reduced global hepatitis B infection, there are still a number of vaccine recipients who do not develop detectable antibody responses. Various novel vaccination approaches, including DNA vaccines, have been used to further improve the coverage of vaccine protection. Our previous studies demonstrat...
Monoclonal antibodies were raised to detergent-extracted cytoskeleton preparations of mouse oocytes. In immunofluorescence microscopy, one of the antibodies, OCS-1, localizes exclusively to epithelial cells in frozen tissue sections, including various simple and stratified epithelia. The antibody decorates a keratin-type of fibrillar, vinblastine-resistant network in various cultured, epithelia...
strongyloidiasis, caused by a nematode parasite so-called strongyloides stercoralis is one of the major human intestinal nematode infections. considering that stool examination for strongyloides larvae is not a sensitive method and immunodiagnostic methods are more applicable for this purpose, so the present study was conducted to compare the somatic (s) and excretory - secretory (es) antigens ...
BACKGROUND Chronic schistosomiasis is associated with T cell hypo-responsiveness and immunoregulatory mechanisms, including induction of regulatory T cells (Tregs). However, little is known about Treg functional capacity during human Schistosoma haematobium infection. METHODOLOGY CD4+CD25hiFOXP3+ cells were characterized by flow cytometry and their function assessed by analysing total and Tre...
A nested polymerase chain reaction (PCR) protocol was developed for rapid genotyping of hepatitis B virus (HBV). During the first PCR round, a universal HBV primer pair was used to amplify the entire pre-S region of the HBV genome. Within the pre-S region, many nucleotide exchanges are observed. These are partly correlated to the serological hepatitis B surface antigen subtypes. Five additional...
