Many different radiolabeled antibodies have been used for radioimmunotherapy and radioimmunoscintigraphy of human diseases in animal experiments. In order to study the in vivo tissue distribution of antibody, we labeled human nonspecific polyclonal IgG with Na125I using chloramine-T method. An animal model was developed by injecting turpentine in the posterior left thigh of Balb/c mice. Tissue ...

BACKGROUND The etiologic agent of Chagas Disease is Trypanosoma cruzi. Acute infection results in patent parasitemia and polyclonal lymphocyte activation. Polyclonal B cell activation associated with hypergammaglobulinemia and delayed specific humoral immunity has been reported during T. cruzi infection in experimental mouse models. Based on preliminary data from our laboratory we hypothesized ...

Mycobacterium leprae-specific and polyclonal immunoglobulin G (IgG) subclass and IgE antibodies in leprosy patients across the histopathological spectrum were determined by using a quantitative enzyme-linked immunosorbent assay. Antibody responses to M. leprae sonicates were detected only in IgG1, -2, and -3 subclasses. Even at 100-times-lower dilutions, very little IgG4 and IgE antibody activi...

Title of Document: DECONSTRUCTING THE POLYCLONAL ANTIBODY RESPONSE TO DENGUE VIRUS Laura Anne VanBlargan, Doctor of Philosophy, 2015 Directed By: Dr. Theodore Pierson, Adjunct Professor, and Dr. Anne Simon, Department of Cell Biology and Molecular Genetics Dengue viruses are mosquito-borne flaviviruses that circulate in nature as four related serotypes (DENV1-4). These emerging pathogens are re...
