Comparisons of the ability of human IgG3 hinge mutants, IgM, IgE, and IgA2, to form small immune complexes: a role for flexibility and geometry.

Flexibility and Geometry Small Immune Complexes: A Role for Hinge Mutants, IgM, IgE, and IgA2, to Form Comparisons of the Ability of Human IgG3

Release of serotonin from human platelets induced by aggregated immunoglobulins of different classes and subclasses.

The ability of human myeloma proteins of different classes and subclasses and of macroglobulins (all aggregated with bis-diazotized benzidine or heat) to aggregate washed human platelets and release [(3)H]-serotonin from the platelets was investigated and compared with the activity of normal IgG and tetanus-antitetanus IgG antigen-antibody complexes. Aggregated IgG1, IgG2, IgG3, IgG4, and norma...

بررسی میزان سرمی ایمونوگلوبولین های IgG و IgM و IgA و IgE و شمارش لنفوسیت های (+B(CD22 در بیماران مبتلا به بیماری بهجت در ایران

The Behcet disease (BD) is a systemic inflammatory disease of unknown etiology. Evidences suggest that at least some of the clinical aspect of the BD may be due to autoimmune responses, these includes elevated levels of immunoglobulins (Igs) and immune complexes. To clarify the molecular basis of the changes in the level of different classes of Igs in BD, we have detected the amount of IgG, IgM...

The two suborders of chiropterans have the canonical heavy-chain immunoglobulin (Ig) gene repertoire of eutherian mammals.

Bats comprise 20% of all mammals, yet little is known about their immune system and virtually nothing about their immunoglobulin genes. We show that four different bat species transcribe genes encoding IgM, IgE, IgA and IgG subclasses, the latter which have diversified after speciation; the canonical pattern for eutherian mammals. IgD transcripts were only recovered from insectivorous bats and ...

Inhibition of IL-13 by Antisense Oligonucleotide Changes Immunoglobulin Isotype Profile in Cultured B-Lymphocytes

The link between IL-13 and bronchial hyper-responsiveness has brought this cytokine as a potential therapeutic target for asthma and allergic diseases. At the present study, we address the role of B cell derived IL-13 in the IgE and other immunoglobulin development. Antisense oligo for human IL-13 m-RNA was used to study IgE down regulation. Human B-lymphocytes were purified by positive selecti...
