Cancer-driven granulo-monocytopoiesis stimulates pathological expansion of tumor-promoting myeloid populations, mostly tumor-associated macrophages (TAM) and myeloid-derived suppressor cells (MDSC). Accumulation TAM and MDSC, enables cancer immune evasion and causes a bottleneck for cancer immunotherapy. Epigenetic alterations in myeloid precursors play a central role in the pro-tumor diversion of these cells. We aim to unveil the causal association between the epigenetic landscape acquired by tumor-associated myeloid cells and tumor immunosuppression, in the perspective to provide new indicators for both responsiveness to therapy and optimization of personalized anticancer treatments.

Adjuvants are key components of vaccines that enhance and/or modulate the immune response to the applied antigen. New adjuvants have been developed in order to target specific components of the body’s immune response, having in goal stronger and longer protection against disease. However, a limited number of adjuvants is currently approved for human use due to their potential safety concerns (e.g. inducing auto-immunity, induction of local or systemic side-effects). Saponin-based adjuvants have been extensively studied for their use in vaccines due to their very distinct immunostimulating activity. Among them, QS-21, a compound isolated from the bark of the Quillaja saponaria Molina tree, shows the unique profile of immunostimulating activity, inducing a balanced Th1/Th2 immune response, which broadens the scope of its potential applications for vaccines against microbial pathogens and also cancer. After being studied in over 100 clinical trials, it is finally approved for human use (herpes zoster vaccine Shingrix®, GSK). However, Quillaja saponins (QS) have inherent drawbacks which restrain their wider use, such as chemical instability, limited supply, laborious purification process, and dose-limiting toxicity. Therefore, there is a need for the development of structurally defined, homogeneous, and simplified QS saponin-based adjuvants with improved chemical stability and synthetic accessibility. Chemical synthesis is currently the only viable way to access structurally defined QS analogs in a sufficient amount for adjuvant screenings and potential application in clinics. The lecture will focus on the recent progress in the design, synthesis, and immunological evaluations of new analogs based on the structure of natural Quillaja saponins.

Coronavirus disease 2019 (COVID-19) is an ongoing pandemic caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), first isolated in December 2019 in Wuhan, China. The clinical features of COVID-19 are highly variable, ranging from asymptomatic patients to severe forms of respiratory failure, and may change remarkably with virus strain and patient’s immune system. But the most dangerous manifestation of this infection is community acquired pneumonia, which often results in lung fibrosis. The persentage of lung damage even after the successful treatment may be more than 80% of fibrosis, so all this patients need the constant oxygen support. The treatment, that includes antifibrotic grugs with the combination of glucocorticoteroids in minimal doses results in the almost complete disappearance of lung fibrosis and normalization of TGFβ and TNFα level, and restoration of lung function.

To date, hyperoxaluria is considered the main risk factor for the formation of oxalate-calcium stones, which account for 75% of all kidney stones. The oxalate-degrading bacteria (ODB) is a diverse group of bacteria consisting of the "narrow-profile oxalotrophs" which use oxalate as the sole source of carbon and energy (e.g. Oxalobacter formigenes) and the "broad-profile oxalotrophs" which use oxalate as an alternative or additional source of metabolism (e.g. Lactobacillus spp., Bifidobacterium spp., Bacillus spp., etc). We will talk on the dichotomy between total fecal oxalate-degrading activity (ODA) and the ODB number in oxalate homeostasis. Moreover we will present a new perspective on the translational relevance of ODA assessing in the prediction of nephrolithiasis formation and personalized prescribing of probiotics or synbiotics.

Biochemical indicators of reactions of bacteria from different biotopes under the influence of heavy metal compounds

Microorganisms play an important role in the functioning of biocenoses influencing geochemical cycles and are exposed to heavy metal ions. The study of the response of microorganisms to the influence of stressors is necessary to understand not only their metabolism, but also their interaction with environmental factors. From various biotopes (Yavorivske lake, coal mine dumps, landfill infiltrates, marine Antarctica) at the Department of Microbiology of Ivan Franko National University of Lviv have been isolated bacteria Chlorobium limicola ІМV К-8, Desulfuromonas acetoxidans ІМV В-738, Rhodopseudomonas yavorovii IMV B-7620, Paenibacillus tundrae ІМV B-7915 and others. According to the results of the study of the influence of various heavy metal compounds on biomass accumulation, pigment biosynthesis, free radical damage of lipids and proteins, antioxidant protection system, fatty acid content in bacterial membranes factor analysis was performed and relationships between these indicators were established. The obtained results are important for understanding the pathways of regulation of bacterial metabolism under stress conditions and degradation of toxic elements by bacteria, the content of which in the environment may exceed the maximum permissible concertation. Strains isolated from environment can be promising for the development of ecobiotechnologies for bioremediation of substrates from both inorganic and organic contaminants.

Isolation and identification of endophytic bacteria from seeds of parasitic plants of selected Orobanchaceae representatives

Endophytic bacteria represent the part of plant microbiome that harbors the inner tissues of the plant and may have an important role in plant growth promotion. Direct or indirect influence of endophytes is achieved via inhibiting plant pathogenic bacteria or by producing various secondary metabolites. Endophytic microbiome studies and identification of compounds synthesized by its representatives can contribute to obtaining effective means for controlling the plant growth. The current talk presents the results of endophytic bacteria isolation and identification from holoparasitic plant species of Orobanchaceae family. Phelipanche ramosa (L.) - one of the most aggressive and economically important broomrape weeds attacking the tomato and tobacco fields and two endemic species Cistanche armena and C. phelypaea are characterized by the production of the large number of the smallest “dust” seeds. The task for isolation and identification of the endophytic micobiomes (unculturable and culturable) from their seeds are complicated, as due to the unique structure of reticulated testa and the endothelium of the seeds coat the appropriate methods of seeds surface sterilization must be selected. The results of 16S rRNA gene sequencing of culturable members of microbiomes and complete microbiome NGS sequencing of the parasitic plant seeds will be presented. Specific attention is drawn to plant growth promoting (PGP) traits of isolated bacterial endophytes that may help to overcome abiotic stress on time of seeds germination.

Antimicrobial and antibiofilm forming properties of medicinal plants: from screening to phytocompositions

Development of bacterial resistance to antibiotics has of late become an issue of global importance. The ability of microorganisms to form biofilm creates the prerequisites for the development of chronic inflammatory processes. Under such conditions, the search for alternative sources of antimicrobial activity becomes a particularly pressing issue. Plant products that combine antimicrobial activity with antioxidant, anti-inflammatory and deodorizing properties are a promising source for such components. The antimicrobial and anti-biofilm forming effect of substances of plant origin opens up good prospects for development of plant-based health and beauty aids. Especially important is development of a series of anti-inflammatory means, with due regard for dominant microbiota associations of human organism. We performed screening of the antimicrobial and antibiofilm forming activity of extracts and essential oils of fifty medicinal plants and selected ones that showed complex antimicrobial and antibiofilm forming activity. The produced phyto compositions proved promising to produce microbiota-correcting antimicrobial agents and preparations subject to its (microbiota’s) individual structural peculiarities.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in December 2019 to cause a global pandemic of coronavirus disease (COVID-19). Many investigations are ongoing to test the compounds already identified as antivirals. Type I interferons (IFN-I), predominantly IFN- and , are a group of cytokines with an important function in antiviral responses. However, they play a complex role in COVID-19 as well as other IFN-inducer antivirals. In this lecture, the role of type IFN-I will be discussed in the pathogenesis and treatment of Covid-19 and results from the investigation of the efficacy of Larifan, the antiviral capable of triggering the IFNs and their signalling pathways, will be analysed.

Bioinformatics is the youngest sister in a family of biological disciplines; it is even younger than many senior scientists working in this field. The birth of this discipline introduced a fundamental shift in biological studies from the hypothesis-driven to data-driven methodology. The rapid development of Next Generation Sequencing (NGS) technologies availed scientists with data on the genetic coding of life, while the latest NGS achievements, e.g. SMRT PacBio, opened a new, yet unexplored, dimension of life encoding by a soft epigenetic engraving of important features of living organisms. One such example is the biotechnological activities of bacteria of industrial importance and antibiotic resistance. Progress in this new area of research is precluded by a shortage of computational tools and algorithms for data mining in raw DNA reads generated by the 3rd generation sequencing technologies and unestablished statistical validation of consequences of epigenetic modifications. The materials of this talk present recent discoveries and future prospects of the SMRT PacBio sequencing and epigenetic profiling in medicine and biotechnology. Special attention is paid to the applicability of new drugs inducing antibiotic resistance reversion through epigenetic modification of DNA of multidrug resistant pathogens.
