Prion diseases have been observed to deregulate the transcription of erythroid genes, and prion protein knockout mice have demonstrated a diminished response to experimental anemia. To investigate the role of the cellular prion protein (PrPC) in erythropoiesis, we studied the protein's expression on mouse erythroid precursors in vivo and utilized a...

Our recent advancements in RNA nanotechnology introduced novel nanoscaffolds (nanorings); however, the potential of their use for biomedical applications was never fully revealed. As presented here, besides functionalization with multiple different short interfering RNAs for combinatorial RNA interference (e.g., against multiple HIV-1 genes), nanor...

Full-text available
Lentiviral (LV) vectors have emerged as powerful tools for basic research and clinical applications because of their ability to stably transduce both dividing and nondividing cells. A wide range of viral envelope (Env) glycoproteins have the ability to associate with the membrane of LV vectors, a process that is referred to as pseudotyping. Pseudot...

We introduce a new concept that utilizes cognate nucleic acid nanoparticles which are fully complementary and functionally-interdependent to each other. In the described approach, the physical interaction between sets of designed nanoparticles initiates a rapid isothermal shape change which triggers the activation of multiple functionalities and bi...

Simple detection of oncomarkers is of paramount importance in cancer diagnosis. Screen-printed carbon electrodes (SPCEs) were modified by streptavidin, which served as a suitable platform for aptamer molecule binding. The electrochemical conditions for soluble epidermal growth factor receptor (EGFR) sensing were studied and optimized. Developed sen...

Full-text available
Lentiviral (LV) vectors have emerged as powerful tools for transgene delivery ex vivo but in vivo gene therapy applications involving LV vectors have faced a number of challenges, including the low efficiency of transgene delivery, a lack of tissue specificity, immunogenicity to both the product encoded by the transgene and the vector, and the inac...
Article
Precise control over the assembly of biocompatible three-dimensional (3D) nanostructures would allow for programmed interactions within the cellular environment. Nucleic acids can be used as programmable crosslinkers to direct the assembly of quantum dots (QDs) and tuned to demonstrate different interparticle binding strategies. Morphologies of sel...
Article
Full-text available
The relatively straightforward methods of designing and assembling various functional nucleic acids into nanoparticles offer advantages for applications in diverse diagnostic and therapeutic approaches. However, due to the novelty of this approach, nucleic acid nanoparticles (NANPs) are not yet used in the clinic. The immune recognition of NANPs is...
Article
Nucleic acids have been utilized to construct an expansive collection of nanoarchitectures varying in design, physicochemical properties, cellular processing and biomedical applications. However, the broader therapeutic adaptation of nucleic acid nanoassemblies in general, and RNA-based nanoparticles in particular, have faced several challenges in...
Article
The unknown immune stimulation by nucleic acid nanoparticles (NANPs) has become one of the major impediments to a broad spectrum of clinical developments of this novel technology. Having evolved to defend against bacterial and viral nucleic acids, mammalian cells have established patterns of recognition that are also the pathways through which NANP...
Article
Full-text available
Nucleic acid-based assemblies that interact with each other and further communicate with the cellular machinery in a controlled manner represent a new class of reconfigurable materials that can overcome limitations of traditional biochemical approaches and improve the potential therapeutic utility of nucleic acids. This notion enables the developme...
Chapter
According to the WHO, we can expect the rise of around 24 million new cases of cancer per year by around 2030 worldwide, which is a 70% increase from 2012. The molecular key players leading to cancer are heterogeneous in respect to tissue origin and may vary from patient to patient, calling for an individualized approach. Nucleic acid biopolymers (...
Article
BACKGROUND Cellular prion protein (PrPC) is expressed on various cell types including red blood cells (RBCs). The PrPC plays a key role in the pathogenesis of prion diseases, but its physiologic function remains unclear. PrPC is expressed on CD34+ hematopoietic stem cells and its expression is regulated during blood cell differentiation including t...

Targeted delivery of bioactive compounds is a key part of successful therapies. In this context, nucleic acid and protein-based aptamers have been shown to bind therapeutically relevant targets including receptors. In the last decade, nucleic acid-based therapeutics coupled to aptamers have emerged as a viable strategy for cell specific delivery. A...

Transmissive spongiform encephalopathies (TSE) are neurodegenerative diseases characterized by depositions of abnormally folded prion protein (PrP(TSE)) in brain. PrP(TSE) is at present the only specific biochemical marker of human and animal TSE. As deposits of PrP(TSE) remain in the body for long periods, there is substantial chance of them being...

2032 Cellular prion protein (PrPc) plays a key role in pathogenesis of prion diseases, however, its physiologic function remains unclear. The involvement of PrPc in hematopoiesis was suggested by importance of its expression for self renewal and survival of long term repopulating hematopoietic stem cells. Prion diseases were shown to deregulate tra...

3213 The cellular prion protein (PrPc) is a highly conserved GPI-linked cell surface sialoglycoprotein which plays a key role in the pathogenesis of neurodegenerative prion diseases. Although PrPc is conserved across species, its normal function is not clearly understood. PrPc tissue distribution varies by cell type or by level of expression in dif...
Article
Recent transmissions of variant Creutzfeldt-Jakob disease by blood transfusion emphasize the need for the development of prion screening tests. The detection of prions in blood is complicated by the presence of poorly characterized cellular prion protein (PrP(C) ) in both plasma and blood cells. According to published studies, most of PrP(C) in blo...

Lepidopteran assemblages in Temnosmrečinská dolina valley (High Tatra Mts, Western Carpathians, Slovakia) were investigated. Recent data about the occurrence of lepidopteran species are compared with those which were obtained 55 years ago. Lepidoptera were monitored at seven sites comprising the subalpine to alpine zone of the valley. Fifteen of th...
Poster
Two recent UK cases of vCJD transmission by blood transfusion emphasize urgent need of donor screening test for prion diseases. Pathological form of prion protein, PrPsc, is currently the only specific marker of prion diseases, but its detection in blood poses significant challenge. Blood contains substantial amount of normal PrPc which supposedly...
