Project title:
Intestinal barrier dysfunction and epithelial-immune cell interactions in plectinopathy

Project description:
Inflammatory bowel disease (IBD) is characterized by compromised intestinal barrier function in association with excessive activation of the mucosal immune system. Using mouse model of plectinopathy we show that absence of plectin, a highly versatile cytolinker, in intestinal epithelium aggravates experimentally induced colitis and potentiates associated carcinogenesis. The major goal of this project is detailed analysis of molecular mechanism underlying governing role of plectin in intestinal barrier maintenance. In addition, we will study the impact of plectin deficiency on initiation and progression of colorectal cancer. We will further develop mouse model with tissue-specific plectin ablation in myeloid cell lineage and characterize it with respect to plectin-controlled epithelial-immune cell interactions. Understanding the mechanisms involved in the plectin-deficiency-mediated pathogenesis of IBD and colorectal cancer is necessary to define new targets for disease screening and strategies for its prevention and treatment.

The successful candidates will learn and utilize advanced cell-biology, molecular-biology, physiology and imaging techniques, while developing and analyzing various mouse models.

Functional characterization of avian sarcoma and leukosis virus receptors

Project description:
Avian sarcoma and leukosis virus (ASLV) served historically as a key model in both virus and cancer research. Our laboratory has long tradition with this model. More recently, we have identified and further characterized some of the cellular receptor molecules employed by the virus for entry into host cells. The current project will aim at elucidating the function that these receptor molecules play in the biology of the chicken cell, and how it impacts the cytopathic effects of the virus infection. The work will be mostly using molecular biology and virology techniques, but will also involve bioinformatic methods (their prior knowledge is not required). We will try to identify selection pressures exerted during avian evolution on the receptor molecules. We will also try to identify endogenous receptor ligands. Lastly, we will try to identify how new virus subgroups are formed by recombination with chicken endogenous retroviruses. Further reading: 1. J Virol, 2005, 79:10408; 2. J Virol, 2004, 78:13489; 3.

Project title:
Contribution of (pre)lamin A – phosphoinositides complexes to intranuclear order

Project description:
Lamins are intermediate filament proteins present in nuclear lamina and, to less extent, in the nuclear interior. They are involved in a variety of nuclear functions, such as regulation of gene expression, DNA replication, DNA repair, chromatin organization, and cellular ignalling. Mutations in lamins cause severe disease – laminopathies. While interactions and functions of lamins in lamina are extensively addressed, much less is known, about the lamin pool in the nuclear interior. Our preliminary data demonstrate that lamin A forms a complex with nuclear myosin I and a phosphoinositide phosphatidylinositol 4,5-bisphosphate. This project focuses on detailed characterization of these complexes by biochemical, structural and advanced microscopy methods using various experimental models. The project will implement molecular biology and biochemistry methods as well as the state-of-the-art imaging techniques including fluorescence, confocal and super-resolution (SIM, STED, STORM) microscopy. The project is supported by recently awarded funding from the Grant Agency of the Czech Republic.

Candidate’s profile (requirements):
M.Sc. (Mgr.) degree or equivalent in molecular/cellular biology or biochemistry, good English, independent thinking, strong interest in basic research and experimental work, dedication to learn and develop new techniques.

Project title:
Phosphoinositides compartments in the cell nucleus – their structure and functions

Project description:
Phosphoinositides are phosphorylated species of phosphatidylinositol. They are present at all membranous structures within a cell (plasma membrane, ER, GA, endosomes and various vesicles) where they direct membrane trafficking and serve as signalling molecules. Surprisingly, phosphoinositides localize also to the cell nucleus, which is internally absent of membrane. We have previously demonstrated that phosphatidyl inositol-4,5-bisphosphate (PIP2) is present in the nucleolus as well as carbon-rich patches which we termed the lipid islets. We have shown that nucleolar PIP2 stimulates activity of RNA polymerase I and other transcription factors such as UBF and fibrillarin and thus modulates transcription of rDNA genes. In the nucleoplasm, lipid islets associate with RNA polymerase II and their absence negatively affects transcription of protein-coding genes. The exact mechanism, however, remains largely unknown. This project focuses on finding (i) the detailed composition of lipid islets as well as (ii) defining a cross-talk between various phosphoinositides within the nucleus, (iii) defining direct protein interacting partners of phosphoinositides, and (iv) elucidating the mechanism by which the phosphoinositides modify nuclear processes, e. g. RNA polymerase II transcription.

The PhD project will implement molecular biology and biochemistry methods as well as the state-of-the-art imaging techniques including fluorescence, confocal and super-resolution (SIM, STED) microscopy. The project is supported by funding from the Grant Agency of the Czech Republic.

PhD Position 3

Project title:
Identifying the interactions of chromatin and the nuclear periphery

Project description:
A nuclear periphery involves a nuclear envelope with a lamina tightly attached to the inner nuclear membrane and nuclear pore complexes facilitating nucleocytoplasmic transport. The nuclear periphery plays a crucial role in chromatin organisation, regulation of gene transcription, gene silencing or in mediating the communication between the nucleus and the cytoplasm. The importance of the nuclear periphery is also demonstrated by number of diseases (called envelopathies) resulting from a mutation in genes encoding for one of the peripheral protein such as lamin or emerin. The structure of the nuclear periphery as well as the role of proteins associated with the periphery in the above mentioned processes is fragmentary. This project focuses on those topics and aims to further uncover the biochemical interactions at the nuclear periphery. The PhD project will implement the state-of-the-art imaging techniques including super-resolution (SIM, STED) as well as molecular biology and biochemistry methods for in-depth studies of the role of periphery associated proteins in chromatin organisation.

Elucidation of the biological role of Tiki, Wnt-specific Metalloproteases

Project description:
The project focuses on TIKI1 and especially TIKI2 (TRABD2A and TRABD2B genes) whose biological role in mammals is still purely understood. TIKIs function as negative regulators of the Wnt signaling pathway, mediating cleavages of N-terminal residues of a subset of Wnt proteins. Phylogenetic analysis shows that Tiki1 and Tiki2 orthologues are highly conserved among vertebrate and mammalian species although the Tiki1 is missing in rodents. The role of Tiki proteases will be studied in mouse and human systems and the work will start with the analysis of our TIKI2 –deficient mice. The aim of this study is to describe the pathophysiologic roles of TIKI2 (TIKI1).

Candidate’s profile (requirements):
M.Sc. (Mgr.) degree or equivalent in molecular/cellular biology or biochemistry, a good command of English, independent thinking but also team player, strong interest in basic research and experimental work, ability to work with animals (rodents – training will be provided).

PhD Position 1

Project title:
It is troublesome without BBSome

Project description:
Primary cilium and immunological synapse are related structures. Both organelles concentrate sensory and signaling receptors of multiple signaling pathways. In addition, structural and functional establishment of these structures is dependent on polarized protein transport and remodeling of actin cytoskeleton. Bardet-Biedl syndrome (BBS) is a severe multiorgan disease (ciliopathy) caused by loss-of-function mutations in several BBS related proteins. BBSome is a complex of eight BBS proteins and regulates two key processes during ciliogenesis. First, BBSome transports multiple receptors to the ciliary membrane. Second, BBSome inhibits activity of RhoA GTPase, which regulates F-actin polymerization. The herein project aims to understand how BBSome regulates actin remodeling during ciliogenesis. Second part of the project will focus on the role of BBSome in the formation of the immunological synapse between T cells and antigen-presenting cells. The PhD candidate will analyze BBS4 deficient mice and generate and analyze BBS7 and BBS4 deficient cell lines. The experimental approaches will include fluorescence microscopy and superresolution microscopy, techniques of biochemistry and molecular biology and immunological assays.

Offer:
We can offer enthusiastic, well-equipped research environment and sufficient funding. The research focuses on solving emerging questions in cell and developmental biology.

Candidate’s profile (requirements):

Track the Tregs

Project description:
Regulatory T cells (Tregs) are crucial players in establishing self-tolerance. However, some aspects of Treg biology are still poorly understood. It is unclear how highly self-reactive T cells decide between negative selection and Treg conversion in the thymus. The PhD candidate will address the role of Foxp3 transcription factor in this cell-fate decision checkpoint using transgenic animal models. Second part of the project will focus on the analysis of the role of pathogen specific Tregs during infection using monoclonal Tregs and Listeria monocytogenes infection. Third part of the project will analyze the heterogeneity of Treg population in the steady-state and during various disease conditions (infection, cancer, and autoimmunity).

Offer:
We can offer enthusiastic environment of a young research team, well-equipped research environment and sufficient funding. The research focuses on solving emerging questions in immunology.

Project title:
Molecular mechanisms of inflammation

Project description:
Inflammation is a principal mechanism of body defense against invading pathogens and its proper mounting is critical for clearing infection. At the same time, the hyper-activation of pro-inflammatory pathways might lead to severe autoimmune disorders and cancer. The initial activation of the immune system requires pro-inflammatory mediators, such as TNF, IL-1, and IL-17. The binding of these cytokines to their receptors on cell surface triggers formation of complicated signaling complexes. Very tight regulation of these complexes is required to ensure adequate activation and termination of inflammatory signaling. However, the precise molecular mechanisms guiding the assembly and activity of these signaling complexes are still largely enigmatic. At first, the candidate will identify novel components of several pro-inflammatory signaling complexes (including IL-17 receptor signaling complex) using mass-spectrometry analysis. Subsequently, roles of the newly identified components will be studied in vitro by analyzing knock-out cell lines generated by Crispr-Cas9 technology. Finally, the candidate will focus on the role of these molecules in vivo using animal models. Altogether, the successful candidate should finish her/his PhD study with deep theoretical knowledge in the field of inflammation and be highly skilled to perform up-to-date molecular biology methods and analysis of mouse models.

Candidate’s profile (requirements):
M.Sc. or equivalent in cell biology, biochemistry, molecular biology, or a related field. We are looking for a highly motivated and enthusiastic candidate with deep interest in science. Prior laboratory experience is advantageous.

Project title:
The mechanistic interplay between DNA strand break repair, RNA processing, and human neurological disease

Project description:
DNA single-strand breaks (SSBs) are the most frequent DNA lesions arising in cells and are a major threat to cell survival and genetic integrity, as indicated by the elevated genetic deletion, embryonic lethality, and neurological disease observed if single-strand break repair (SSBR) is attenuated1. Based on our recent exciting data2 we will address the extent to which the impact of SSBs extends to other neurodegenerative diseases and to normal human ageing. In addition, the project will address the mechanisms by which SSBs trigger neurodegeneration, and will employ cutting edge techniques in molecular and cellular biology, including genome editing by CRISPR-Cas9 technology. The successful applicant will join a dynamic and well-funded laboratory with training opportunities in laboratories in both Prague and the UK.
