HPV infection correlates with the progression of oropharyngeal carcinogenesis.
<p>(A) Percentage of HPV 16 positive infection in patient tissues with normal oral mucosa, dysplasia, cancer in situ and cancer was shown. (B) Representative flow cytometry image of CD11b+ LIN- HLA-DR- CD33+ MDSCs in tissues of OPSCC patients with HPV-negative and HPV-positive. We first examined the percentage of LIN- HLA-DR- cells, and then screened the percentage of CD11b+ CD33+ cells in LIN- HLA-DR- cells. This image showed that the percentage of CD11b+ LIN- HLA-DR- CD33+ MDSCs in HPV-negative and HPV-positive OPSCC patients was 9.39% and 13.81%, respectively. (C) Representative immunohistochemical image (C3) of MPO in cancer tissues of OPSCC patients. C1 and C2 were H& E staining and C2 was amplification of C1.</p

Chronic inflammation correlates with the progression of oropharyngeal carcinogenesis.
<p>(A) The morphology of neutrophils (Black arrow) and lymphocytes (White arrow) in cell smear. (B) Percentage of different degrees of chronic inflammation in cell smear of indicated types of tissues were shown. The results showed that there was significantly difference between the percentage of moderate-severe inflammation in the cell smear of dysplasia and normal oral mucous (<i>P</i><0.001), and the inflammation degrees showed no different in the cell smear of dysplasia, cancer in situ and cancer (<i>P</i>>0.05). Error bars represent the meanĀ±SD of triplicate experiments. (C) Representative image of normal oral mucosa, dysplasia, cancer in situ and cancer with mild inflammation. (D) Percentage of different degrees of chronic inflammation in indicated types of tissues are shown. The results showed that there was significantly difference between the percentage of moderate-severe inflammation in the tissues of dysplasia and normal oral mucous (<i>P</i><0.001), and the inflammation degrees showed no different in dysplasia, cancer in situ and cancer specimens (<i>P</i>>0.05). Error bars represent the meanĀ±SD of triplicate experiments. (E) Transcription levels of IFN-Ī³, IL-10, IL-12, and IL-2 in normal oral mucosa, dysplasia, cancer in situ and cancer tissue, relative to GAPDH, determined by quantitative RT-PCR. Error bars represent the meanĀ±SD of triplicate experiments.</p
