Merkel Cell Polyomavirus Strains in Patients with Merkel Cell Carcinoma
We investigated whether Merkel cell carcinoma (MCC) patients in France carry Merkel cell polyomavirus (MCPyV) and then identified strain variations. All frozen MCC specimens and 45% of formalin-fixed and paraffin-embedded specimens, but none of the non-MCC neuroendocrine carcinomas specimens, had MCPyV. Strains from France and the United States were similar.
متن کاملPD-L1 expression in the Merkel cell carcinoma microenvironment: association with inflammation, Merkel cell polyomavirus and overall survival.
Merkel cell carcinoma (MCC) is a lethal, virus-associated cancer that lacks effective therapies for advanced disease. Agents blocking the PD-1/PD-L1 pathway have demonstrated objective, durable tumor regressions in patients with advanced solid malignancies and efficacy has been linked to PD-L1 expression in the tumor microenvironment. To investigate whether MCC might be a target for PD-1/PD-L1 ...
متن کاملImaging in Patients with Merkel Cell Carcinoma
Merkel cell carcinoma (MCC) is a rare, aggressive neuroendocrine tumor of the skin with a mortality rate of approximately 25% (Peloschek et al., 2010). Accurate assessment of nodal involvement in patients with MCC predicts significantly overall outcome (Smith et al., 2012 and Ortin-Perez et al., 2007). Due to the rarity of this highly aggressive disease, only a few imaging reports on MCC were p...
متن کاملmerkel cell polyomavirus infection in a patient with merkel cell carcinoma: a case report
conclusions the findings of this study are consistent with the hypothesis that local, systemic, or tumor-induced immunosuppression may allow the mcpyv to initiate skin aggressive cancer. it is necessary to maintain regular check over patients taking immunosuppressive medications for mcpyv infection. since there is not any information about detection and molecular biology analysis of mcpyv among...
متن کاملMerkel Cell Polyomavirus Positive Merkel Cell Carcinoma Requires Viral Small T Antigen For Cell Proliferation
These findings contradict existing evidence showing MCV sT protein expression in MCVMCC cancer tissues (Shuda et al., 2011) and cell lines (see Figure. 2, Houben et al., 2010) (Guastafierro et al., 2013). To investigate this discrepancy, we tried replicating Angermeyer et al's results using the same antibodies to detect MCV sT (CM8E6 (Kwunet al., 2009), CM5E1 (Shuda et al., 2011) and 2T2 ((Wang...
