Barbora Hadámková Determination the mechanism of entry F. tularensis into B lymphocytes Diploma thesis Charles University, Faculty Of Pharmacy in Hradec Králové Study program: Pharmacy Background: Besides processing the research with basics knowledge of the problem, the main aim of the study was the analysis of mechanism of entrance of intracellular bacteria Francisella tularensis into B cells. Methods: The B cells, which we obtained through peritoneal lavage from mice Balb/c, we blocked using antibodies individual complement receptors, B cell receptor and Fcƴ receptor. The population of the cells was infected by bacteria F. tularensis LVS/GFP opsonized by complement and/or by antibodies. Using flow cytometry we measured the percentage of infection of individual subpopulations of B cell B1a, B1b and B2 and we evaluated the influence of blocking and opsonization on the infection. Results: From the measured data, we can say that the percentage of infected B cells after infection by F. tularensis opsonized by complement is increased. This increase was more distinct in subtype of B cells B1b and B2. On the other hand, the opsonization F. tularensis by antibodies did not affect the infection. We also found out, that blocking of Fcƴ receptor has decrease the infection, if we used for infection of B cells...
