Antibody Response to Homografts
Antigenic differences between certain inbred strains of mice which could not be revealed by hemagglutination techniques were readily disclosed by lymphocyte cytotoxicity. With an improved cytotoxicity test lymphotoxic titers were as high as 1:512 with non-hemagglutinating A anti CBA antisera. In other mouse strain combinations, a close parallel of both types of antibody activity was obtained. T...
متن کاملDepression by Antibody of the Immune Response to Homografts and Its Role in Immunological Enhancement
This paper reports tests of two hypotheses that have been proposed to account for the enhanced growth of tumor homografts in the presence of antiserum reactive with the graft (immunological enhancement). According to the first hypothesis, enhancement is due to some "physiological" alteration in the tumor, induced by its contact with antiserum, which insures its survival despite the hostile resp...
متن کاملAntibody Response to Human Extracellular HER2 Subdomain Proteins in Mice
Background: In addition to passive immunotherapy using anti-HER2 monoclonal antibodies, active immunotherapy via HER2 targeting is an interesting approach to inducing specific anti-tumor immune responses. We have recently reported the immunogenicity of HER2 subdomains following DNA immunization and HER2 protein boosting. In the present study, we evaluated the immunogenicity of different HER2 ex...
متن کاملHumoral Aspects of the Immune Response to Homografts
Isoimmune sera, prepared in BALB/c mice by immunization with living or lyophilized tissue from C57Bl/6 mice, were found to possess both hemagglutinating and cytotoxic activity for donor cells. Comparative titrations indicated a good correspondence between these two activities. Absorbtion with living or dead donor tissue caused removal or proportionate reduction of both activities. The results a...
متن کاملAntibody Response to Pneumocystis jirovecii
We conducted a prospective pilot study of the serologic responses to overlapping recombinant fragments of the Pneumocystis jirovecii major surface glycoprotein (Msg) in HIV-infected patients with pneumonia due to P. jirovecii and other causes. Similar baseline geometric mean antibody levels to the fragments measured by an ELISA were found in both groups. Serum antibodies to MsgC in P. jirovecii...
