These chemokines are involved in the recruitment and activation of macrophages, neutrophils, eosinophils, basophils, monocytes, and natural killer cells (NK-cell) to the inflamed endometrium [32,33], whereas the NF-κB signaling pathway protects a survival of immune cells in the face of bacterial infections or irritation [34] (Figure 1). The gene discussed is NFKB1; the disease is bacterial infectious disease.
