The Centre of New Technologies invites to a webinar by
Prof. Jan Brezovsky,
Faculty of Biology, Adam Mickiewicz University in Poznań and the International Institute of Molecular and Cell Biology in Warsaw,
Title: Ligand-transport pathways in proteins: structure, dynamics, function & modulation
Date: 27th November 2020 (Friday)
Time: 12:00 pm (Central European Time)
Host: prof. Joanna Trylska
Virtual seminar: Zoom link will be given before the webinar.
Enzymes are indispensable for the function of every living cell, catalyzing the efficient execution of a vast number of concurrent chemical reactions. These reactions take place in the enzymes’ active sites exposed on the protein surface or, very frequently, buried deep inside its core. Access of substrates and release of reaction products via molecular tunnels is essential for the function of the buried sites. Aside from enabling efficient catalysis, tunnels also constitute a structural basis of various regulatory mechanisms that are critical to the living cell like substrate inhibition and cooperativity. Despite their utmost importance, tunnels are rarely explicitly considered in protein research due to obtrusive challenges in their identification arising from their often fleeting nature. The ensuing knowledge gap precludes linking tunnel mutations to pathologies, targeting the ligand-transport process with tunnel inhibitors, and designing proficient enzymes with the buried active sites.
In this talk, we will review challenges connected with uncovering transient tunnels, their engineering, and functional impacts on enzyme function, and briefly outline future steps to be taken in order to narrow the knowledge gap to deliver necessary insights relevant to enzymology, precision medicine, drug discovery, and protein engineering.

Obesity is a risk factor for diseases such as type II diabetes, heart disease and fatty liver disease. An international research team, to which researchers from the UW Faculty of Chemistry belong, identified a new factor that offers a potential new therapeutic strategy for obesity. Their study has now been published in the prestigious journal “Nature Metabolism”.
According to the World Health Organisation, obesity has reached epidemic proportions globally, with at least 2.8 million people dying each year as a result of being overweight or obese. A central element in the development of obesity is adipose tissue, which comprises fat cells (so-called adipocytes, specialised to store fat) and macrophages (immune system scavenger cells, which are typically associated with the destruction of microbes).
Scientists from Austria, together with researchers from Germany and Australia, and a team of scientists from the University of Warsaw have discovered the signalling pathways responsible for the development of a valuable type of adipose tissue macrophage (ATM) in obesity, which prevents lipotoxicity. Lipotoxicity is the process whereby fat molecules are deposited in non-adipose tissues.
Like Dr. Jekyll and Mr. Hyde
The researchers working at the UW Faculty of Chemistry: Dr. Maria Górna, Dr. Marta Kulik and Prof. Paulina Dominiak, specifically studied the PI3K signalling pathway. This is a major metabolic regulator, since it regulates fat storage and plays a major role in the cellular reaction to the hormone insulin. In obesity, diminished insulin action or insulin resistance leads to type II diabetes, which is linked to high blood glucose levels.
Dr. Gernot Schabbauer from the Institute of Vascular Biology and Thrombosis Research at MedUni Vienna’s Center for Physiology and Pharmacology has been studying the PI3K signalling pathway in immune cells for several years. “The key role of PI3K in metabolic processes is proven but its role in adipose tissue macrophages was hitherto unclear,” stresses Dr. Schabbauer.
“ATMs are like Dr Jekyll and Mr Hyde – in obesity, they can either be good or bad. We assumed that an active PI3K signalling pathway could tip the balance in favour of ‘good’,” adds Julia Brunner, co-lead of the study.
Using techniques such as multicolour flow cytometry, lipidomics, cellular respiration tests and several animal models, the scientists discovered that sustained activity of the PI3K signalling pathway can tip the balance within macrophages for the better: this notably produces specialised ATMs, which are characterised by increased numbers of MARCO (macrophage receptor with collagenous structure) scavenger receptors on their surface.
“We discovered that these MARCO-expressing ATMs are professional lipid scavengers. These cells absorb fat MARCO-dependently and break it down, thereby preventing it from finding its way into the bloodstream,” explains Andrea Vogel, co-lead author of the study and doctoral candidate in immunology at MedUni Vienna. Omar Sharif, a co-senior author of the study, adds: “Metabolic syndrome and lipotoxicity are characteristic features of obesity. Our work indicates that a higher lipid intake and improved energy metabolism of the ATMs helps to maintain systemic metabolic health. This can have far-reaching impacts for a number of metabolic diseases.”
The researchers from the University of Warsaw analysed the structure of MARCO and assessed its potential for lipid binding. “It is a receptor known for binding and cleaning up as diverse objects as bacteria or oxidized Low-density lipoprotein, but its role in buffering lipids is new”, says Maria Górna. “This study is only the beginning of our collaboration with colleagues from Austria, and we have ideas on how to next test the direct involvement of MARCO in lipid uptake.”
Subsequent studies will now be conducted to establish whether PI3K signalling can also have a lasting influence on the ATM population in humans.

Welcome Point is an information point where everyone can get help and information during their stay at the University of Warsaw. There are two locations of this unit. First WP office is available on the main campus, and the second one operates on the campus in Ochota.
The new Welcome Point was open on the campus in Ochota district two weeks ago. Students from Russia, Armenia, India, Thailand and Ukraine, who get education at UW, visited it seeking help and guidance. They were interested in finding information on, e.g. library services under pandemic restrictions, scholarships, students’ union, dormitories and the procedures regarding registration for classes and lectures.
Incoming students are welcome with small gifts, including student packs and tourist information regarding our university, Warsaw and Poland. The new spot in Ochota facilitates access to information and advice for exact and natural sciences students and those who live in dormitories at Żwirki i Wigury Street.
“I am glad that Welcome Point is also on the campus in Ochota now. We can complete all the formalities related to, e.g. the employment of international scientists much faster and more efficiently, and above all, here, on the spot. We can save a lot of time,” says Professor Ryszard Kutner, who invited a visiting lecturer Dr. Zbigniew Struzik to the UW Faculty of Physics (It was possible thanks to the University’s Integrated Development Programme (ZIP).
Welcome Point remains open for visitors who follow precautionary measures on:
- wearing a mask,
- keeping a safe distance from other people (2 meters),
- using hand sanitizers.
Due to a dynamic situation, the Welcome Point team asks to make an appointment by e-mail before visiting the office. All the matters which do not require in-person contact should be handled by e-mail or by sending a message on the Welcome group on Facebook.
The new spot of Welcome Point is situated on the ground floor of the CeNT building (on the campus in Ochota district), open from Monday to Friday, 9:00 am – 4:30 pm.
