This study investigates how Nr-CWS influences tumor-associated macrophages (TAMs) immune functions through macrophage receptor with collagenous structure (MARCO)-mediated mechanisms.<h4>Methods</h4>Cervical tissues of three cervical intraepithelial neoplasia (CIN) patients receiving Nr-CWS monotherapy and HPV infection turning negative were collected before and after treatment, and gene microarray analysis was performed. Here, MARCO is linked to neoplasm.
