Merkel cell polyomavirus (MCPyV) is the first polyomavirus clearly associated with a human cancer, i.e. the Merkel cell carcinoma (MCC). Polyomaviruses are small naked DNA viruses that induce a robust polyclonal antibody response against the major capsid protein (VP1). However, the polyomavirus VP1 capsid protein epitopes have not been identified to date. The aim of this study was to identify t...
Merkel cell carcinoma (MCC), a highly aggressive skin tumour with increasing incidence, is associated with the newly discovered Merkel cell polyomavirus (MCPyV). Studies on MCC and MCPyV as well as other risk factors have significantly increased our knowledge of MCC pathogenesis, but the cells of origin, which could be important targets in future therapies, are still unknown. Merkel cells (MCs)...
MCC: Merkel cell carcinoma MCPyV: Merkel cell polyomavirus PET/CT: position emission tomography/ computed tomography PD: programmed death TVEC: talimogene laherparepvec UV: ultraviolet INTRODUCTION Merkel cell carcinoma (MCC) is a rare, aggressive cutaneous malignancy with a propensity for locoregional recurrence and hematogenous spread. MCC typically presents in elderly patients with fair comp...
Diagnostic Methods for and Clinical Pictures of Polyomavirus Primary Infections in Children, Finland
We used comprehensive serodiagnostic methods (IgM, IgG, and IgG avidity) and PCR to study Merkel cell polyomavirus and trichodysplasia spinulosa-associated polyomavirus infections in children observed from infancy to adolescence. Comparing seroconversion intervals with previous and subsequent intervals, we found that primary infections with these 2 viruses were asymptomatic in childhood.
The single most important causative factor for malignant melanomas of the skin is UV radiation. However, this is not true for melanomas on body surfaces sheltered from the sun; thus, it is important to seek new causative factors of melanoma genesis. Human papillomaviruses and gammaherpesviruses are associated with human skin cancer; for example, human papillomavirus types 5 and 8 are associated...
Merkel cell carcinoma (MCC) is a rare but aggressive neuroendocrine skin neoplasia. The merkel cell polyomavirus (MCPyV), a double-stranded DNA tumor virus was discovered in 2008. It is found in approximately 80% of human MCC and is suspected to play a role in MCC development [1]. Both, small tumor and the aminoterminal moiety of the large tumor antigen, were found to be expressed in MCPyV-posi...
Merkel Cell Polyomavirus (MCPyV) was recently discovered as a novel human polyomavirus that is associated with ~80% of Merkel Cell Carcinomas. The Large Tumor antigen (LT) is an early viral protein which has a variety of functions, including manipulation of the cell cycle and initiating viral DNA replication. Phosphorylation plays a critical regulatory role for polyomavirus LT proteins, but no ...
