Analýza exprese inhibitorů serinových proteáz v klíštěti \kur{Ixodes ricinus} pomocí kvantitativní real-time PCR
HAUSEROVÁ, Simona
Tick saliva contains a lot of biological active substances helping them to succesfully complete their feeding which is neccesary for their next development. Both proteinaceous and non-proteinaceous molecules including protease inhibitors are present in tick saliva. The biggest family of these proteases are serpins. Serpins are involved in many biological processes as blood coagulation, fibrinolysis, apoptosis or inflammation. The aim of this diploma work was to determine expression profiles of 10 serpins from nymphs of Ixodes ricinus fed for different times using quantitative real time PCR. For chosen genes (IRS 10, IRS 20) dsRNA for silencing of the gene was prepared and using RNA interference the role of these genes during tick (I. ricinus nymphs) feeding and transmission of Borrelia afzelii spirochetes, a vector of Lyme borreliosis, was evaluated.Tick saliva contains a lot of biological active substances helping them to succesfully complete their feeding which is neccesary for their next development.
