WebVarious cytokines produced by T H 2 cells orchestrate antibody class switching, which allows B cells to switch between the production of IgM, IgG, IgA, and IgE as needed to carry out specific antibody functions and to provide …
WebJul 30, 2012 · Immunoglobulin class-switch recombination deficiencies (Ig-CSR-Ds) are rare primary immunodeficiencies characterized by defective switched isotype (IgG/IgA/IgE) production. Depending on the molecular defect in question, the Ig-CSR-D may be combined with an impairment in somatic hypermutation (SHM).
WebIgA is the most abundant antibody class and provides a first line of defence at mucosal surfaces. Class switching to IgA occurs through both T-cell-dependent and T-cell-independent pathways, and ...
