we found that compared with the PBS group, the distribution of F4/80+ macrophages of the tumour and lymph in the MCC group gradually increased; compared with MCC + NIR group, the macrophages of the tumour and lymph in the PfCC+NIR treatment group were also significantly increased, indicating that MCC and antimicrobial peptides could induce macrophages response in tumours (Fig. 7l, m). The gene discussed is MCC; the disease is neoplasm.
