Exploratory drilling: how to set up, carry out, and evaluate a seroprevalence study.

Seroprevalence studies represent a very important tool to find out what fraction of population has already met with the new type of coronavirus (e.g. SARS-CoV-2).

Seroprevalence of IgG antibodies against measles in health care workers of the Strakonice Hospital.

Aim: Due to mandatory vaccination introduced in the Czech Republic since 1969, only few measles cases were reported annually until recently. However, a rapid increase of cases has been recorded in last two years. In contrast to the pre-vaccination era, in recent measles outbreaks, many cases have been reported among vaccinated adults.

Drosophila imaginal disc growth factor 2 is a trophic factor involved in energy balance, detoxification, and innate immunity.

Drosophila imaginal disc growth factor 2 (IDGF2) is a member of chitinase-like protein family (CLPs) able to induce the proliferation of imaginal disc cells in vitro. In this study we characterized physiological concentrations and expression of IDGF2 in vivo as well as its impact on the viability and transcriptional profile of Drosophila cells in vitro. We show that IDGF2 is independent of insulin and protects cells from death caused by serum deprivation, toxicity of xenobiotics or high concentrations of extracellular adenosine (Ado) and deoxyadenosine (dAdo).

Pharmacological caspase inhibitors: research towards therapeutic perspectives.

Caspases are key molecules of apoptosis and the inflammatory response. Up-regulation of the caspase cascade contributes to human pathologies such as neurodegenerative and immune disorders. Thus, blocking the excessive apoptosis by pharmacological inhibitors seems promising for therapeutic interventions in such diseases.

Characterization of the Drosophila adenosine receptor: the effect of adenosine analogs on cAMP signaling in Drosophila cells and their utility for in vivo experiments.

Adenosine receptors (AR) belonging to the G protein-coupled receptor family influence a wide range of physiological processes. Recent elucidation of the structure of human A2AR revealed the conserved amino acids necessary for contact with the Ado moiety. However, the selectivity of Ado analogs for AR subtypes is still not well understood.
