MALBOR-ECO - Ecology of host specificity in vector-borne parasites
Ekológia hostiteľskej špecifickosti vektormi prenášaných parazitov
Program: APVV
Project leader: MVDr. Derdáková Markéta PhD.
Annotation:Emergence and spread of new infectious diseases is becoming a never more serious medical, societal and economical problem. Increasingly more diseases expand their ranges or re-emerge in areas from where they had been wiped out long ago. The emergence of new diseases is most frequently attributed to global environmental changes, including climate change, land use changes and changes in human concentration. A key role in the spread of new diseases is attributed to changed patterns of animal migration and therefore also of their parasites – potential vectors of diseases. Despite great effort, knowledge into the causes of the successful transmission and spread of vector-borne parasites is still only poorly understood. Consequently, theoretical prediction models of the spread of diseases and efforts to halt this spread are not effective. The aim of this project is to increase the understanding of the causes of host specifity and the regulation of circulation of vectorborne parasites. We will use two globally important study systems that involve tick-borne Borrelia spirochetes and insect-borne Plasmodium and Haemaproteus haemosporidians. The objective is to identify taxonomic, genetic and phylogenetic structure of local host associations and to assess if host specificity is a result of host specialization by parasites or i tis a result of host and vector ecology.

The role of neuropeptides and receptors in regulation of pathogen transfer from ticks to their hosts
Funkcia neuropeptidov a ich receptorov pri regulácii prenosu patogénov z kliešťov na hostiteľa
Program: APVV
Project leader: RNDr. Žitňan Dušan DrSc.
Annotation:Ticks are very important vectors of dangerous pathogens, but regulatory mechanisms required for their successful transmission into the host are poorly understood. Likewise, physiological processes controlling function of the salivary glands, gut and gonads during their life cycle have not been elucidated. Our published and preliminary data indicate that several specific peptidergic neurons innervate these organs which are the most important reservoirs of pathogens. Our unpublished experiments suggest that identified neurons control activity of these organs and associated transmission of pathogens during tick feeding on the host. In this project we will use a combination of techniques (immunohistochemistry, molecular biology and bioinformatics) to identify regulatory molecules (neuropeptide and their receptors) and neuronal pathways important for normal function of the salivary glands, digestive system and reproductive organs of the ticks Ixodes ricinus and I. scapularis. We also propose to study the role of specific neuropeptides and their receptors in transmission of pathogens (Rickettsia helvetica and Borrelia burgdorferi) from these tick organs into laboratory mice using RNAi techniques. Expected results may provide tools for effective suppression of pathogen transmission and development of procedures to inhibit reproductive capability of ticks as dangerous ectoparasites of humans and animals.

SGT - Of Sheep, Goats and Tick-borne Encephalitis virus
O ovciach, kozách a víruse kliešťovej encefalitídy
Program: APVV
Project leader: MVDr. Derdáková Markéta PhD.
Annotation:Emerging tick-borne encephalitis from May this year in eastern Slovakia, has been the largest in number of cases for the last five years. As usual, it was supposed that products from raw sheep's milk had been the causative agens. Such enormous epidemic is striking due to the regular routine screening of sheep milk. We have known many foodborne infections from history, but most of cases was related to goat's milk. The aim of the proposed project is a comparative analysis involving sheep respectively goats foodborne infections. With regard to exact criteria it will be selected a representative number of farms from all Slovakia. We will investigate the milk of sheep and goats, as well as ticks collected from direct observation of the animals. It will be done for each farm. Sample will be examined by highly sensitive molecular biological methods for the virus presence. From animal blood we evaluated the serological status of all investigated animals. Evaluation of the results we can see how engaged sheep and goats in the case of food-borne infections. In the case of virus positive samples by sequencing analysis we obtain very valuable information about the genetic diversity of the TBEV in our country. An equally important outcome of the project will be specific methodological recommendations for farmers in terms of preventing foodborne disease.

The role of neuropeptides and their receptors in regulation of endocrine and reproductive organs in the silkworm (Bombyx mori)
Úloha neuropeptidov a ich receptorov pri regulácii aktivity endokrinných a reprodukčných orgánov priadky morušovej (Bombyx mori)
Program: APVV
Project leader: Ing. Roller Ladislav PhD.
Annotation:Insects are widespread and evolutionary extremely successful group of animals that show unique adaptations during development and reproduction. These adaptations are mediated by special endocrine glands including corpora allata (CA) that produce juvenile hormones (JH) and various modifications of reproductive organs. These important organs are under control of regulatory compounds that include neuropeptides produced by neurons and endocrine cells. However, neuroendocrine processes controlling activity of the CA in different developmental stages are not fully understood. Our preliminary and published data indicate that JH production from the CA is controlled by several peptidergic cells, whose specific functions in this process remain to be determined. Likewise, the role of neuropeptides during mating, fertilization and egg laying is not fully understood. Therefore, in this project we will identify neuropeptides, receptors and peptidergic cells involved in regulation of the CA and reproductive organs in the silkworm Bombyx mori. We will analyze neurons directly innervating these organs, as well as endocrine Inka cells that may control these organs via humoral pathways. We will employ techniques of molecular biology and immunohistochemistry to identify signaling molecules and peptidergic cells, while transgenic approaches in combination with physiological and behavioral assays will be used to determine roles of specific neuropeptides and their receptors. Expected results are important for understanding of molecular mechanisms underlying regulation of development and reproduction, which require complex neuroendocrine communication between peripheral organs and CNS.
