Doctoral degree in full-time or combined form. The language of instruction is Czech.
The programme can be studied only as a single subject.
The aim of the study is to educate students in the field of life sciences and to prepare them as highly qualified specialists for scientific activities. The introductory part of the study concentrates on deepening theoretical and practical knowledge. At the same time, separate literary research on the assigned topic of the doctoral dissertation is being prepared. The core of students’ activities lies in their own scientific work. Students are guided by the supervisor to be able to independently implement all phases of a scientific project. They are also encouraged to the processing of the obtained experimental data methodologically relevant, as well as to their interpretation and subsequent presentation in various forms. The programme is highly multidisciplinary and, compared to the traditional study of biology, is more methodologically and analytically focused. Thanks to access to state-of-the-art infrastructure, students can better combine various biochemical, bioanalytical and visualization instrumental techniques with solving biological problems, which increases the impact of their scientific activities and their flexibility in the labor market, including positions in academia, e.g. within existing biotechnology companies or in newly emerging spin-offs.
The concept of the programme reflects the current level of scientific knowledge, the needs of the labor market, and overall trends in the field. At the same time, it benefits from the support system within the so-called CEITEC PhD School, which presents the concept of care for doctoral students involved in research teams at CEITEC and at the same time emphasizes expanding the competencies of the future graduates in socio-managerial, technological and soft skills. That will enable them to conduct their follow-up research in an efficient and modern way and provide them with a very good overview of the ethical aspects of research necessary for life sciences research and research and development in general.Life for Science. Science for Life.
The programme aims at the international employment of graduates. It is prepared in Czech and English versions, most subjects are taught, all seminars and, to a large extent, research is conducted in English. The environment at CEITEC MU is significantly international, so students are exposed to communication in English not only during official teaching but practically everywhere within CEITEC.
An important contribution to the acquisition of practical skills of DSP students of Life Sciences is their natural involvement in research teams at CEITEC MU. In this way, students can immediately acquire the necessary practical skills for team management and research projects, acquire networking skills and directly engage in research projects and grants (including H2020 projects and ERC grants) to understand the issues of research funding. Students can also routinely use eleven uniquely equipped shared laboratories and gain significant practical experience in this form within the so-called internal internship, or in another institution in the Czech Republic as part of an external internship (recommended volume is 10 working days (80 working hours).
A compulsory part of the study obligations in the doctoral study program is completing part of the study at a foreign institution for at least one month, or participating in an international creative project with results published or presented abroad or another form of student direct participation in international cooperation.
The program supports Collaborative PhD, i.e. completing a doctoral project in cooperation with a commercial entity. That allows students to expose themselves to a more non-academic environment. Also, within the TAC system, students cooperate more often with experts from practice.

Annotation:
Most approved drugs act on cell-surface targets or enter cells passively. For compounds with poor solubility or low membrane permeability, encapsulation in liposomes is a proven strategy to improve these properties. However, encapsulated drugs often remain trapped within the liposome, limiting their bioavailability and therapeutic efficacy. This project will investigate coiled-coil peptides as a scaffold for assemblies that enable controlled membrane fusion and intracellular cargo delivery. Using a combination of coarse-grained molecular dynamics simulations with the Martini force field and complementary biophysical approaches, we will elucidate the peptide features and molecular mechanisms that enable efficient membrane fusion. The outcomes of this research will advance our understanding of peptide-mediated membrane fusion and provide a framework for the rational design of delivery systems for biotechnological and therapeutic applications.

With nearly 10 million lives claimed annually, cancer remains one of the leading causes of mortality worldwide, highlighting the urgent need for more effective treatments. One promising strategy involves mRNA-based cancer immunotherapy vaccines, which require a drug delivery system capable of reliably reaching the cytosol. Developing such delivery systems is challenging: they must ensure cytosolic delivery and therapeutic efficacy while maintaining safety, long-term stability, and compliance with scalable manufacturing standards - including high mRNA loading efficiency and uniform particle size. Current lipidand polymer-based systems offer distinct advantages but integrating lessons from both may help develop more effective next-generation carriers. A major limitation remains the incomplete understanding of nanoparticle assembly and disassembly under diverse physiological conditions (e.g., extracellular fluids, endosomal compartments, cytosol). This project will use coarse-grained molecular simulations, complemented by in-house experimental validation, to gain molecular insights in the controlled system assembly and disassembly. Our goal is to guide the rational design of improved mRNA delivery systems to advance the efficacy of cancer immunotherapy.

Annotation:
Cancer remains one of the leading causes of mortality worldwide, claiming nearly ten million lives each year. One promising treatment is cancer immunotherapy using mRNA encapsulated in lipid vesicles, which facilitate efficient drug transport into target cells. However, the delivery of mRNA into the cell remains a challenge due to limited endosomal escape. To overcome the endosomal escape barrier, this project aims to computationally design proteins that induce fusion between lipid vesicles and endosomes. Using mesoscopic simulations, we will identify the key structural features of proteins with a transmembrane domain that promote membrane fusion. These insights will inform the rational design of coiled-coil peptide sequences with said features and assess their capacity to induce membrane fusion using Martini coarse-grained simulations. This research will elucidate the molecular mechanism of protein-mediated membrane fusion, establishing a framework for the rational design of fusogenic proteins. The designed proteins will enable the development of lipid vesicles with increased endosomal escape efficiency, which has the potential to improve the intracellular delivery of mRNA. Collectively, these advances will contribute to the broader vision of developing clinically relevant platforms that expand the therapeutic potential of nucleic acid medicines and accelerate their translation into effective therapies.
