The effect of IgG levels on the number of natural killer cells and their Fc receptors in chronic inflammatory demyelinating polyradiculoneuropathy

Abstract

The study implies that IVIg infusion induces a substantial decline in the number of peripheral NK cells and a suppression of NK-cell-mediated cytotoxicity. We propose that these impairments of the NK cells contribute to the therapeutic effect of IVIg in CIDP.
