Detekce a kvantifikace inhibitorů proteáz v klíštěti \kur{Ixodes ricinus} pomocí monoklonálních protilátek
 VANÍČKOVÁ, Martina
Inhibitors of proteases in tick saliva play an important role during tick feeding. Tick saliva contains a wide range of bioactive components which are able to modulate host imunity. Therefore, ticks are able to feed for a long time and transfer tick-borne diseases pathogens. The risk of transfer can be significantly reduced by deactivation of theese protease inhibitors. In this study I made monoclonal antibodies for detection and quantification of two serine protease inhibitors in tick saliva and other tick-body parts.

Vliv klíštěcích slin na fagocytózu borelií dendritickými buňkami
 MARŠÁLKOVÁ, Eliška
In this study we examined the effect of the tick saliva from I. ricinus and the effect of recombinant protein IRS-2 from the saliva of I. ricinus on dendritic cells derived from the mice bone marrow. We studied their effect on the production of cytokines by dendritic cells after the stimulation by B. burgdorferi, their effect on the expression of genes, that participate in phagocytosis, and the impact of the tick saliva on phagocytosis of B. burgdorferi by dendritic cells.

The effect of tick´s serpin IRS-2 on dendritic cells activated by TLR4 ligand
 POSPÍŠILOVÁ, Šárka
IRS-2 is the inhibitor of serine proteases from the Ixodes ricinus tick. My task in this thesis was to find out the effect of the IRS-2 on dendritic cells activated by TLR4 ligand or by Borrelia afzelii. This effect was studied on several levels. I focused on the cytokine production, the expression of costimulatory molecules and cell signaling pathways. The results show that the IRS-2 may inhibit the expression of costimulatory molecules CD-80 a CD-86 on the cell surface, but this finding needs to be confirmed again. The production of cytokines was not affected by the IRS-2. The effect of the IRS-2 on the activity of p38, Erk1/2 nor NF-?B in LPS stimulated cells vas not observed. The fosforylation of STAT 3 in cells activated by the B. afzelii was lowered by the IRS-2.

Transcriptomic and functional analysis of salivary proteins from the tick \kur{Ixodes ricinus}
 CHMELAŘ, Jindřich
This thesis was focused on the identification and characterization of the salivary proteins from Ixodes ricinus, the European vector of Lyme disease and tick-borne encephalitis causative agents. In the first part of this work, the the transcriptomic approach was used in order to identify and describe I. ricinus salivary proteins. The second part is dealing with functional and structural characterization of the salivary protein named IRS-2 (I. ricinus serpin-2).
