Secreted or nonsecreted Ag expressed by recombinant Listeria monocytogenes can prime CD8 T cells. However, Ag-specific memory CD8 T cells confer protection against bacteria secreting Ag, but not against bacteria expressing the nonsecreted form of the same Ag. This dichotomy may be explained by a long-standing hypothesis that nonsecreted Ags are less effective than secreted Ags at inducing a pro...
BACKGROUND & OBJECTIVE Sodium butyrate (NaBT) can inhibit proliferation and induce differentiation of various tumor cells. This study was to investigate effects of NaBT on the proliferation and differentiation of human gastric carcinoma cell line AGS and explore the possible mechanism. METHODS AGS cells were treated with 0, 1.0, 2.0 and 4.0 mmol/L of NaBT. Cell proliferation was detected by M...
*These authors contributed equally to the work in this manuscript.We have previously identified a distinct class of antibodies expressed by B cells in the cerebrospinal fluid (CSF) of early and established relapsing remitting multiple sclerosis (RRMS) patients that is not observed in healthy donors. These antibodies contain a unique pattern of mutations in six codons along VH4 antibody genes th...
Abstract Plasmodium spp. cause more than half a million malaria deaths annually and the only approved vaccine, RTS,S, based on P.falciparum (Pf) circumsporozoite protein (CSP), confers incomplete non-durable protection. A strategy to improve vaccines involves combining Ags of different stages such as sporozoite (spz) liver stage (LS). This promises broader repertoire specific antibodies (Ab), C...
Background and purpose: Adenocarcinoma gastric cancer is one of the most common cancers of upper gastrointestinal tract. Many natural compounds are known to have anti-tumor activities through induction of tumor cell apoptosis. Tribulus terrestris is a plant with antioxidant and anti-inflammatory effects that has been recommended in the world and Iranian traditional medicine. These effects have ...
BACKGROUND AND AIM The human CD24 antigen is a small heavily glycosylated cell surface protein, which is expressed in a large variety of solid tumors,including gastric cancer. Enriched on the surface of many tumor cells,CD24 promotes tumor growth,invasion and metastasis and confers resistance to some chemotherapeutic drugs.In this study, we investigated the possible effect of CD24 suppression o...
aim : in this paper effect of combinational usage of calprotectin and etoposide on ags cell line is studied. background : application of combined toxic agents such as etoposide and cicplatin are commonly used for chemotherapy purposes. as a matter of fact, calprotectin and etoposide were both applied on human gastric adenocarcinoma cell line (ags) as antitumor agents. both calprotectin and etop...
To determine a suitable condition for in vitro infection model of Cryptosporidium parvum, four different cell lines, AGS, MDCK, HCT-8 and Caco-2, were used as host cell lines which were cultured at various concentrations of added supplements. These supplement include fetal bovine serum (FBS), sodium choleate, ascorbic acid, folic acid, calcium pantothenate, para-aminobenzoic acid and pyruvate a...
Gastric cancer (GC) is one of the most frequent types around world and drugs which are used currently as anti-cancer chemotherapy hold adverse side effects on normal cells tissues, that calls for a strong need to find new agents prevent treat GC. Extracts from certain plants contain compounds with health potentials minimal effects; such plant Crataegus azarolus commonly called hawthorn. hawthor...
Abstract Pregnancy constitutes an immunological paradox, where despite the competent maternal immune system, semi-allogeneic fetus evades rejection. The mechanisms at maternal-fetal interface and mother’s secondary lymphoid tissues (SLTs) that dodge immunologic attack to fetus, remain largely unknown. Passage of extracellular vesicles (EVs) is a mechanism cell-to-cell communication transfer ant...
