Project description:Viruses are the second leading cause of cancer worldwide, and human papillomavirus (HPV)-associated head and neck cancers are increasing in incidence in the United States. HPV preferentially infects the crypts of the tonsils rather than the surface epithelium. The present study sought to characterize the unique microenvironment within the crypts to better understand the host tropism of HPV to a lymphoid rich organ. Laser-capture microdissection of distinct anatomic areas (crypts, surface epithelium, and germinal centers) of the tonsil coupled with transcriptional analysis and multi-parameter immunofluorescence staining was performed and demonstrated that the tonsillar crypts are enriched with myeloid populations which co-express multiple canonical and non-canonical immune checkpoints, including PD-L1, CTLA-4, HAVCR2 (TIM-3), ADORA2A, IDO1, BTLA, LGALS3, CDH1, CEACAM1, PVR, and C10orf54 (VISTA). The resident monocytes may foster a permissive microenvironment that facilitates HPV infection and persistence. Furthermore, the myeloid populations within HPV-associated tonsil cancers co-express the same immune checkpoints, providing insight into potential novel immunotherapeutic targets for HPV-associated head and neck cancers.

Project description:Recently, submandibular abscesses associated with Actinomyces denticolens have been reported in horses. The actinomycotic clumps have been observed in the tonsillar crypts. The aim of this study was to demonstrate colonisation of A denticolens in equine tonsils. Twelve equine tonsils obtained from a slaughterhouse were divided into two parts for histopathological examination and for isolation of A denticolens. When actinomycotic clumps were found in these tonsillar crypts, immunohistochemistry using hyperimmune serum against A denticolens (DMS 20671) was performed on the serial sections. To determine whether Actinomyces-like bacteria isolated using immunoantigenic separation technique were A denticolens, the isolates were analysed for the 16S rRNA gene sequence. Actinomycotic clumps were found in the tonsillar crypts of 11 (91.7 per cent) horses. The clumps were of the saprophytic type accompanied with the feedstuffs, but a few clumps were surrounded by inflammatory cells. A denticolens antigens were immunodetected not only in the clumps of 11 (100 per cent) tonsils, but also in the tonsillar parenchyma. Six isolates obtained from four tonsils showed 99.7-99.9 per cent similarity to A denticolens in the 16S rRNA gene sequence. In horses, the colonisation sites of A denticolens are the tonsils, thus the authors suggest that the tonsils provide the intrinsic infection site for A denticolens.

Project description:Purpose: The goals of this study are to understand the transcriptional changes of human tonsillar epithelial cells UT-SCC-60B in response to EV71 infection and determine the differential expressed genes Methods: Transcriptional profiles of human tonsillar epithelial cells UT-SCC-60B and human tonsillar epithelial cells infected with EV71 were generated by next generation sequencing, in triplicate, using Illumina X-ten/NovaSeq. The sequence reads that passed quality filters were analyzed abundance of mRNA using StringTie, the FPKM values of genes and transcripts were calculated by Ballgown of R software, alternative splicing events were determined by rMATS Results: Using an optimized data analysis workflow, we mapped more than 36 million sequence reads per sample. Total 11137 gene counts and 26860 transcript counts were identified in human tonsillar epithelial cells, 11347 gene counts and 27994 transcript counts were identified in EV71-infected human tonsillar epithelial cells. Total 96 genes and 499 transcripts were down-regulated, 105 genes and 550 transcripts were up-regulated according the criteria that fold changes are more than 1.5, p value less is than 0.05 and mean of FPKM value is more than 0.5 to defined as the differential expressed genes or differential expressed transcripts. Total 11563 novel genes and 14927 novel transcripts were identified and 3266 novel transcripts had the potential coding probabilities. Finally, total 5742 genes occurred alternative splicing events. Conclusions: Our study represents the first detailed analysis of the transcriptional changes of human tonsillar epithelial cells UT-SCC-60B in response to EV71 infection, this results will provide novel insight into the interaction between human tonsillar epithelial cells and EV71

Project description:We used an IL4-capture assay followed by FACS sorting, to isolate IL4-secreting TFH cells from a human tonsil and compared their transcriptomic profiles with CXCR5hi PD1hi IL4-negative tonsillar TFH cells and IL4-producing CXCR5neg non-TFH cells (TH2 cells). Our studies validate the notion of functionally distinct TFH subsets and identify genes that are specifically expressed in and define the human IL-4 secreting TFH cell subset.
