Immunosuppressive Cytokine Interleukin-10 mRNA Expression Correlates with Tumour Progression in Oral Squamous Cell Carcinoma

Conclusions: These results suggest that tumour infiltrating lymphocytes decrease with progression of the tumour, whereas interleukin-10 expression remains constant around the tumour. These data also suggest that interleukin-10 may be produced not only by T cells but also by tumour cells.
