January 2022 | New preprint published

Preprint figure

In our recent preprint, we show that defects in red pulp macrophages - cells responsible for maintaining blood homeostasis - occur early in aging and disrupt iron turnover, contributing to elderly anemia.

November 2021 | New grants awarded

PRELUDIUM grant awardees

We are delighted to announce that two of our Ph.D. students received their own PRELUDIUM grants from the National Science Centre (NCN).

Natalia Szulc will study how the cullin-RING ubiquitin ligase complexes avoid premature degradation, and Pankaj Thapa will investigate the molecular mechanism of the activity switch of the ubiquitin ligase CHIP.

September 2021 | Lecture at the 25th Science Festival in Warsaw

Science Festival 2021

We are honored to participate in the 25th Science Festival in Warsaw, one of the most significant popular science events in Poland. High school students warmly received our presentation on the secrets of Caenorhabditis elegans and its important role in aging research.

We hope that this tiny creature intrigued our listeners, and our lecture provided an overview of the current state of knowledge on mechanisms of aging.

August 2021 | Our research on the cover of EMBO reports

August 2021 EMBO reports cover

Our research on muscular exopheresis in Caenorhabditis elegans is featured as a cover of the August issue of EMBO Reports!

Here we show that exophers are not only a storage compartment for cellular waste, but that muscular exopheresis represents a previously uncharacterized nutrient management program associated with nourishing the next generation of progeny. 

August 2021 | New preprint published

Scheme of role of UFD-2/CHN-1 complex in lipid synthesis

What drives the prominent quality control ubiquitin ligase CHIP? Our new preprint on bioRxiv describes the mechanism by which CHIP is activated by another ubiquitin ligase, UFD-2, which enables the regulation of proteostasis and lipid metabolism.

Our results define the mechanism of synergistic cooperation of CHIP and UFD-2, which promotes structural gain of function in CHIP and regulates S-adenosylhomocysteinase, an enzyme crucial for cellular methylation and phosphatidylcholine synthesis.

Research unit FOR 2743 logo

The research unit FOR 2743 integrates mechanobiology and proteostasis research to elucidate how cells and tissues cope with force-induced protein unfolding. We identified mechano-protective proteostasis factors and signalling networks that regulate responses to mechanical stress.

Thanks to the extended funding we will further decipher principles of mechanical stress protection under physiological and pathophysiological conditions. You can find more information here and here

July 2021 | New article published

Scheme of mechanical stress protection system

During critical moments like differentiation, adhesion, and migration cells use sophisticated mechanisms that protect them from mechanical stress. Moreover, these mechanisms are also essential for maintaining tissues such as skeletal muscle, heart, and kidney as well as the immune system.

Here you can find our article, where we discuss recent advances in our understanding of mechanical stress protection.


March 2021 | New article published   

Scheme of UBB+1 level on cell fitness

Our article on the different cellular effects of the intriguing mutant ubiquitin protein UBB+1 was published in Frontiers in Molecular Biosciences.

You can read here about how UBB+1 may extend lifespan, while on the other hand also leads to aggregation of toxic proteins.

We received extension of the EMBO Installation Grant for the next 2 years!

January 2021 | NCN GRIEG grant opened 

NCN and Norway grants logos

Project Cellular adaptation to cold, funded by the NCN GRIEG grant & the Norwegian Financial Mechanism 2014 – 2021 for 1.499.998 EUR was opened.

We cannot wait to start the studies, together with our partner from the University of Oslo Prof. Rafał Ciosk, on how Caenorhabditis elegans can resist low temperature.
