All together, we showed that both cytokine and chemokine production in the endometrial tumors may participate to the alteration of NK cell function, as IL-6 and IL-1β are increased in the tumor, and recruitment, as chemoattractants CCL27, CXCL12, and CCL21 are significantly reduced in the tumor. The gene discussed is CCL27; the disease is endometrium neoplasm.
