(Submitter supplied) Early diagnosis of oral squamous cell carcinoma (OSCC) remains an unmet clinical need. Therefore, elucidating the initial events of OSCC preceding tumor development could benefit OSCC prognosis. Here we define the Langerhans cells (LC) of the tongue and demonstrate that LC protect the epithelium from carcinogen-induced OSCC by rapidly priming αβT cells capable of eliminating γH2AX+ epithelial cells, whereas γδT and NK cells are dispensable. more...

(Submitter supplied) The immune system plays a key role in the protective response against oral cancer; however, the tumour microenvironment (TME) is able to impair this anti-cancer response by modulating T helper (Th) responses and promoting an anti-inflammatory environment. Regulatory T cells (Tregs) and Th2 effector cells (Teff) have been associated with bad prognosis in oral squamous cell carcinoma (OSCC), however, it is unknown the main immunomodulatory mechanisms associated with the enrichment of these subsets in OSCC. more...

(Submitter supplied) Genome wide DNA methylation profiling of normal and adjacent OSCC samples. The Illumina Infinium 450k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 4,50,000 CpGs in tissue samples. Total 21 samples were taken including 10 paired and 1 unpaired tissues. 6 were HPV Positive and 5 were HPV negative.

(Submitter supplied) A better understanding of molecular changes during oral tumorigenesis may help defining new personalized prevention strategies. In order to test this hypothesis, we analyzed whole-genome expression changes in a murine model of oral carcinogenesis, induced by an oral carcinogen (4-NQO) We generated genome-wide expression profiles of microdissected cells from murine tongue at each step of oral tumorigenesis: normal mucosa, hyperplasia, dysplasia and tumor.

(Submitter supplied) Head and neck squamous cell carcinoma (HNSCC) arises through exposure to environmental carcinogens or malignant transformation by human papillomavirus (HPV). Here, we assessed the transcriptional profiles of 131,224 single cells from peripheral and intra-tumoral CD45+ immune populations from HPV– and HPV+ HNSCC and healthy donors. A spectrum of transcriptional signatures in immune lineages ranging from similar to highly divergent was present in the tumor microenvironments (TME) in HPV– and HPV+ HNSCC. more...

(Submitter supplied) Background: Anti-tumor immunity is highly heterogeneous between individuals; however, underlying mechanisms remain elusive, despite their potential to improve personalized cancer immunotherapy. Head and neck squamous cell carcinomas (HNSCCs) vary significantly in immune infiltration and therapeutic responses between patients, demanding a mouse model with appropriate heterogeneity to investigate mechanistic differences. more...
