Fig. 4.

NK cells before and after high dose intravenous immunoglobulin (hdIVIG) in patients with eczema (n = 3, ○, Δ, and □) and vasculitis (n = 1, ▴) within the total lymphocytes (a), the CD3⁻CD8^dim subpopulation (b) and the CD3⁻CD8⁻ subpopulation (c). The beginning of the lines represent the values before hdIVIG, the end of the lines the values immediately after hdIVIG. Double-positive cells for CD16 and CD56 become negative for CD16, especially in the CD3⁻CD8^dim subpopulation. Unless otherwise stated the Immunotech MoAb for CD16 is used. CD56 does not change. A discrepancy between Ortho Diagnostic and Immunotech antibodies is demonstrated.
