Recurrent miscarriage is associated with a decline of decidual natural killer cells expressing killer cell immunoglobulin‐like receptors specific for human leukocyte antigen <scp>C</scp>

Abstract

This is the first report to demonstrate that RM is associated with a decline in the frequency of decidual NK cells expressing KIR specific for human leukocyte antigen (HLA)-C, and in which gestational stage was considered. The results suggest that KIR phenotype contributes to the pathogenesis of the disease, and that assessment of KIR may serve as a diagnostic tool.
