        Detection of Class Switching and IgE Synthesis in Human B Cells

        互联网

        We observed that mast cells, as other cells expressing the CD40 ligand CD154, can trigger IgE synthesis in B cells in the presence of interleukin (IL)-4. Numerous complementary techniques can be used to follow the succession of molecular events leading to IgE synthesis. This chapter will illustrate how human B cells (na�ve or memory) can be purified, stored, and cultivated in medium that is permissive for IgE synthesis and stimulated with IL-4 or IL-13 and CD40 activation, the latter being induced by soluble CD154, anti-CD40 antibodies, or CD154-expressing cells. All these molecules are expressed by mast cells. The quantification of the ε-sterile transcript synthesis by polymerase chain reaction or Northern blot, the ε excision circles produced during immunoglobulin heavy chain locus rearrangement by polymerase chain reaction, and the IgE production by enzyme-linked immunosorbent assay will be described.
