Research ArticleOpen accessAll words, across the recordHumoral Immune Responses to Various Antigens in the Asterids: A. gibbosa and A. rubensMichel LeclercImmunizations with various antigens of the sea stars Asterina gibbosa and Asterias rubens produce specific humoral immune reactions which initiate the antibody factor. This antibody factor is correlated with kappa genes and could be composed of 4 kappa chains. It is the first time that such phenomenom was described in an invertebrate. …American Journal of Immunology, Vol. 8, Issue 4 · 15 Feb 2013 · 7,306 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordImmunity to Pneumococcal Vaccine in Splenectomized β-Thalassemia PatientsAbdolreza Sotoodeh Jahromi, Mohammad Reza Farjam, Alireza Makarem et al.Problem statement: Splenectomy is accompanied by a lifelong risk of overwhelming post splenectomy infection, mainly caused by encapsulated bacteria such as Streptococcus pneumoniae. The mortality rate in those infected patients remains high. Therefore the pneumococcal polysaccharide vaccine has been recommended. Approach: To obtain information on the immunity levels of pneumococcal antibody, in splenectomized β-thalassemia patients in south of Iran. Patients … …American Journal of Immunology, Vol. 8, Issue 2 · 25 May 2012 · 7,403 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordAntibiotic Susceptibility and Immunomodulatory Potential of Chosen Bacterial PathogensM. Sujatha, P. Dhasarathan, B. KarthickProblem statement: Antibiotic susceptibility is still the best way for bacterial pathogen escape mechanism against immunity. Approach: In the present investigation, bacterial pathogens like Staphylococcus aureus, Escherichia coli, Aeromonas hydrophila, Klebsiella and Pseudomonas aeruginosa were used to screen antibiotic susceptibility and immunomodulatory potential. Results: All the test pathogens were sensitive to all the test antibiotics 11±2 mm) except penicillin. The … …American Journal of Immunology, Vol. 6, Issue 2 · 30 Jun 2010 · 7,829 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordHyper-Ag-specific Ab Production in NC/Nga Mice is not associated with Deletion Polymorphism in the Promotor Region of the FcγRIIB GeneTohru Sakai, Mariko Nakamoto, Emi SutoProblem statement: NC/Nga (NC) mice produced high levels of ovalbumin (OVA)-specific IgG, IgG1 and IgG2a. We previously found deletion polymorphisms in the promoter region of fcgr2b in NC mice. To determine whether this mutation causes a hyper-humoral immune response, we generated congenic BALB/c mice carrying the NC-type fcgr2b allele (NC fcgr2b) and analyzed humoral immune response and FcγRIIB on germinal … …American Journal of Immunology, Vol. 5, Issue 3 · 31 Dec 2009 · 7,364 accessesView PDF Cite
