Analýza protilátkové odpovědi u BK virové infekce / Analysis of antibody response during BK virus infectionTomanová, Tereza January 2019 (has links)
BK virus is a human polyomavirus which is highly prevalent in the population. The virus is usually not very dangerous to its host, but it may cause complicati- ons in immunosuppressed patients. These complications commonly appear after kidney transplantation because BK virus persists in kidney epithelial cells. There are four subtypes of BK virus and it might be clinically important to screen for the identity of subtypes in matched pairs of donors and recipients of the kidney. This determination of the subtype specific antibodies by simple test could help to manage complications after the surgery. During previous project the ELISA test that could serologically differentiate between two main BK virus subtypes (I and IV) was designed, but its development is complicated by the fact that there is a strong cross-reactivity between the BK virus subtypes and antibodies. The modification of antigen towards better specificity might be required to succeed. Consequently, the main aim of this diploma thesis was to map important spots of major capsid protein VP1 of BK virus, particulary in EF and DE loops, which could participate in binding of antibodies. This aim was addressed by targeted mutagenesis of the gene coding VP1 protein in the region of the respective loop. Nucleotides coding two surface aminoacids...

Studium rozpoznáni polyomavirové infekce sensory vrozené imunity / Sensing of MPyV infection by innate immunity sensorsRjabčenko, Boris January 2021 (has links)
Host sensors that recognize pathogen associated molecular patterns and the mechanisms of innate immune response to mouse polyomavirus (MPyV) infection were the main topics of current work. We found that MPyV did not induce interferon (IFN) production during early events of infection, but induced interleukin-6 (IL-6) and other cytokine production without inhibiting virus multiplication. Cytokine microenvironment changed the phenotype of adjacent non infected fibroblasts toward the cancer-associated fibroblast (CAF)-like phenotype. We identified Toll-like receptor 4, a sensor of the innate immunity system, to be responsible for infection dependent IL-6 production. In an effort to determine whether and where virions are released from endosomal compartments into the cytosol, we found that the hydrophobic domains of minor capsid proteins, exposed on the surface of virions after their partial disassembly in the ER, play an important role in effective escape of virions from the lumen part of endoplasmic reticulum into the cytosol, Although naked, partially disassembled virions appear before translocation to the nucleus in the cytosol, viral DNA is not recognized by cytosolic sensors at this phase of infection Sensing of MPyV resulting in IFN production occurs first during viral replication. Mutant virus,...
