Objective Fetal uterine survival depends on maintaining an immune balance between the
mother and fetus. This study aimed to investigate the correlation of blood peripheral natural …

Background Women with elevated natural killer (NK) cell frequency and function during
pregnancy, suffer from recurrent pregnancy loss (RPL). In the present study, the possible …

The aim of this study was to identify the candidates for natural killer (NK) testing and to
define the best methodology. For this purpose a prospective study was performed on 73 …

Background: The purpose of the study was to determine the cut-off values for peripheral and
uterine natural killer (pNK, uNK) cells in fertile controls and in women with recurrent …

We aimed to compare the proportion of peripheral blood natural killer (NK) cells (CD3–
CD56+) and T-cell large granular lymphocytes (CD8+ CD57+) during preconception in a …

Study objective The current knowledge on recurrent pregnancy loss (RPL) is largely limited,
with up to 70% of RPL cases still classified as unexplained. More than 30% of patients with …

Problem Dysregulated natural killer (NK) immunity and T‐cell immunity are associated with
recurrent pregnancy loss (RPL). We aim to define clinically relevant NK and T‐cell …

Background To evaluate the association of serum tumour necrotic factor (TNF)‐α and
interferon (IFN)‐γ levels with IVF treatment outcome and peripheral blood NK cells. Methods …

Peripheral blood NK cytotoxicity assay (NKC) is one of the commonly utilized diagnostic
tools for recurrent pregnancy losses (RPL) and repeated implantation failures (RIF). In this …

OBJECTIVE: To investigate the cytokine expression by peripheral blood natural killer (NK)
cells of women with recurrent spontaneous abortion (SAB) or implantation failures. DESIGN …
