IFNL1 and lip and oral cavity carcinoma: Although OECM1 cells retain key properties of the oral epithelium (grow in tight sheets, and MxA is induced in these cells by IFN-λ1, a Type III interferon, but not by IFN-α2, a Type I interferon [48]), a next step would be to include additional oral cancer cell lines and to also evaluate primary human gingival or immortalized gingival cell lines in these investigations.
