The B cell is a vital contributor to humoral immunity. The B cell-specific antigen CD20 is expressed during B cell development, starting at the pre-B cell level and persists through B cell differentiation, but is lost during terminal differentiation to plasma cells. Rituximab is a monoclonal antibody that destroys both normal and malignant B cells that have CD20 on their surfaces and is ther...

bordetella pertussis infects the respiratory tract of the human host and causes whooping cough in children. the nature of immunity against bordetella pertussis infection and disease is poorly understood. the aim of this study was to investigate cell mediated immunity in mice immunized with outer membrane component of cell wall, of b. pertussis. a group of mice were immunized with outer membrane...

in eukaryotes, vesicle trafficking is regulated by the small monomeric gtpases of the rab protein family. rab11, (a subfamily of the ypt/rab gene family) an evolutionarily conserved, ubiquitously expressed subfamily of small monomeric rab gtpases, has been implicated in regulating vesicular trafficking through the recycling of endosomal compartment. in an earlier communication, we have shown th...

In the present study, properties of silver nanoparticles (AgNPs) such as average size, size distribution andmorphology were investigated by Tollens, polysaccharide, modified polysaccharide and microbial methods.The synthesized AgNPs were characterized by UV-visible spectroscopy, scanning electron microscopy(SEM), transmission electron microscopy (TEM), dynamics light scatterin...

the aim of this work was to see whether tamarin immunisation with recombinant vaccinia virus expressing epstein barr virus latent proteins could prime t cells which were, on activation, able to inhibit the outgrowth of epstein barr virus transformed cells in vitro. the vaccination appeared to be successful as all vaccinated tamarins developed vaccinia lesions. however, the vaccination protocol ...

Introduction: The vaginal flora is a dynamic ecosystem that can be easily altered. Although, there are four causes of vaginal discharges which cover almost 95% of vaginaitis. Candidal Vaginaitis is an infection of the vagina’s mucous membranes by Candida albicans (CA). Present study attempted to Candidal Vaginitis in women referred to health centers in Yazd and the role of innate & cell-mediate...

fcεri, the high affinity receptor for ige plays a critical role in triggering the allergic reactions. it is responsible for inducing mast cell degranulation and deliberation of allergy mediators when it is aggregated by allergen and ige complexes. fcεri on the mast cells consists of three subunits; α chain directly binds ige, β chain and dimmer of γ chains together mediate intracellular signali...

Objective(s): Juglone is isolated from many species of the Juglandaceae family and used as an anti-viral, anti-bacterial, and anti-tumor therapeutic. Here, we evaluated juglone-induced antitumor effect in ovarian cancer SKOV3 cells. Materials and Methods: MTT assay was performed to examine juglone anti-proliferative effect. Cell cycle and apoptosis were studied using flow cytometry in juglone-t...

background: the hbv-x (hbx) protein is believed to contribute to the development of hcc. however, the molecular mechanisms involved in hbx-mediated hepatocarcinogenesis remain obscure. in this study, the effect of hepatitis b virus x gene and its protein product hbxag on expression of p53 gene in hep g2 cell line was investigated. methods: viral dna extracted from hbv-positive serum and hbx gen...
