Merkel cell polyomavirus (MCPyV) is a recently discovered human virus, having it's genome often integrated in a genome of Merkel carcinoma cells. Although this type of carcinoma is not so usual, it is very aggressive and it's incidence has been rising in last few years. It is not surprising that this virus is nowadays in the centre of scientific interest, as well as other pathogens and mechanisms affecting human life. Because the virus was discovered not so long ago, its research has been at the whole beginning. This diploma thesisaims to contribute to the study of this virus from the molecular-virology point of view. A neutralizing monoclonal antibody, type IgG2a, targeted against the main capsid protein of MCPyV, VP1, and recognizing its conformational epitote was prepared. This antibody was then used for a pilot study of VP1 VLPs MCPyV movement in mammalian cells. Results showed that the studied virus, at least particularly, utilizes caveolin-1-carrying vesicles for its movement in cells (colocalisation of VP1 VLPs and caveolin-1 was observedColocalisation with EEA1 marker of early endosomes, LamP2 marker of endolysosomal compartments or with BiP marker of endoplasmic reticulum was sporadic but significant. These preliminary results suggest that MCPyV might utilise an endocytic pathway leading...
