Immunology B Cell Immunodeficiency

Several cytokine receptors utilize the common cytokine receptor {gamma} chain ({gamma}c), and mutations in {gamma}c result in the condition known as X-linked severe combined immunodeficiency (XSCID). Lack of signaling through the interleukin-7 (IL-7) and IL-15 receptors leads to a loss of natural killer and T cells in XSCID patients, although the cause of the B cell defect is not established. Ozaki et al. observed that B cells from mice lacking IL-21 receptor had altered antibody production. When combined with a loss of IL-4 signaling, a severely impaired immunoglobulin G response was observed that is strikingly similar to that seen in XSCID individuals.
