Reactivity of synthetic SAG1 (p30) peptide sequences with RH, S273 and Beverley strain-induced anti-Toxoplasma gondii antibodies.
OBJECTIVES We compared the reactivity of IgG1 and IgG2a antibodies in mouse sera after infection with virulent RH and low-virulent S273 and Beverley strains of Toxoplasma gondii against RH SAG1 recombinant p30 (rp30) and synthetic SAG1 peptides. METHODS Infected mouse serum samples were collected 9 days after infection, and the level of total IgG, IgG1 and IgG2a against the RH SAG1 rp30 prote...
متن کاملCloning and sequencing of Toxoplasma gondii major surface antigen (SAG1) gene
Genetic typing methods of T. gondii strains have been extensively perfected in recent years. From a technical point of view, many tools usable for genetic studied on single-copy loci have been used: RFLP, PCR-RFLP, sequencing, RAPD-PCR and isoenzyme analysis. We described the cloning and sequence analysis of the gene which encodes the major surface antigen (SAG1 or P30) of T. gondii. SAG1 is ...
متن کاملAnti-cyclic citrullinated peptide antibodies in ulcerative colitis, and its relation with disease activity
Background : Ulcerative colitis an inflammatory bowel disease (IBD) and chronically idiopathic immune related that associates with extraintestinal manifestations such as arthritis. Despite of the highly specificity ofanti-cyclic citrullinated peptide (CCP) antibodies for rheumatoid arthritis, their role in IBD remains unclear . There are only a few studies on the prevalence of anti-CCP antibo...
متن کاملBrain Tissue Cysts in Infected Mice with RH-Strain of Toxoplasma gondii and Evaluation of BAG1 and SAG1 Genes Expression
BACKGROUND Toxoplasma gondii is an obligate intracellular parasite that infects humans at high prevalence rates. The virulent RH strain of T. gondii is generally considered to have lost its cyst forming capacity. This study performed to obtain tissue cysts in mice infected with tachyzoites of RH strain treated with sulfadiazine (SDZ). It provides the opportunity to analyze the conversion of tac...
متن کاملInfluence of protein flexibility and peptide conformation on reactivity of monoclonal anti-peptide antibodies with a protein alpha-helix.
Monoclonal antibodies against an alpha-helical region of the iron-containing, oxygen-binding protein myohemerythrin were isolated following immunization of mice with either the whole protein or a peptide homolog of the helix. Three distinct epitopes within the myohemerythrin helix were identified. The individual residues within two of these epitopes that were essential for antibody binding were...
