Presence of immunoglobulin (Ig) M and IgG double isotype-bearing cells and defect of switch recombination in hyper IgM immunodeficiency.
We established a transformed B cell line expressing both IgM and IgG on the cell surface from a patient with hyper IgM immunodeficiency using Epstein-Barr viruses. DNA and RNA of the cells were analyzed. DNA rearrangements of Ig JH gene loci were observed on both chromosomes. Cloning and DNA sequence analyses showed that one has a VHDHJH structure while the other has a DHJH structure. Southern ...
متن کاملAnalysis of Immunoglobulin (Ig) Isotype Diversity and Igm/D Memory in the Response to Phenyl-Oxazolone
The distribution of immunoglobulin (Ig) isotypes within specific B cell clones in vivo after immunization is not well defined. Using an IgV(H)/CDR3- and isotype-specific reverse transcription polymerase chain reaction method, we have carried out a survey of the diversification of the isotype in a splenic response to phenyl-oxazolone (phOx) on a chicken serum albumin carrier. The phOx-specific V...
متن کاملIkaros controls isotype selection during immunoglobulin class switch recombination
Class switch recombination (CSR) allows the humoral immune response to exploit different effector pathways through specific secondary antibody isotypes. However, the molecular mechanisms and factors that control immunoglobulin (Ig) isotype choice for CSR are unclear. We report that deficiency for the Ikaros transcription factor results in increased and ectopic CSR to IgG(2b) and IgG(2a), and re...

چکیده هدف از این کار بررسی الکترواکسیداسیون کتکول و مشتقات آن در حضور 4-فنیل سمی کاربامازید بوده است اکسیداسیون کتکولها ترکیبات نا پایدار کینونها را تولید می کنند که این ترکیبات می تواند در واکنش مایکل بعنوان پذیرنده نوکلئوفیل عمل نمایند. در ادامه اکسایش کتکولهای (a-c1) را درحضور 4-فنیل سمی کاربامازید در محلول آب/استونیتریل (90/10)بوسیله ولتامتری چرخه ای و کولن متری در پتانسیل ثابت مورد بررسی ...
15 صفحه اولCharacterization of human immunoglobulin (Ig) isotype and IgG subclass response to Bartonella henselae infection.
Serologic parameters of cat scratch disease (CSD) were evaluated by Western blot analysis. Sera from patients with serologically confirmed CSD antigen were screened for immunoglobulin (Ig) isotype-specific as well as IgG subclass-specific reactivity against Bartonella henselae whole-cell antigen. Bartonella-negative control sera were used to determine baseline antibody activity. Heterogeneous B...
