„Mitochondria in Aging, Cancer and Cell Death” conference

On November 30th 2023 in Coimbra stared „Mitochondria in Aging, Cancer and Cell Death” international conference where I had the opportunity to give the talk entitled "Revealing of metabolic alterations in primary fibroblasts of patients with Neurodegeneration with Brain Iron Accumulation - subtype MPAN". Moreover, two postdocs from our MitoLab: Magdalena Lebiedzinska-Arciszewska and Patrycja Jakubek presented their recent work during the poster session.


I am very happy that I could meet my colleagues and friends in a such amazing scientific environment.

Visiting the LXV General Józef Bem High School

On November 22nd I have visited the LXV General Józef Bem High School with inclusion classes. My visit was aimed to familiarize students with the disease called: Neurodegeneration associated with iron deposition in the brain (NBIA). Moreover, I presented how scientists from the Nencki Institute are investigating metabolic disfunction in the fibroblasts derived from patients affected by this disease.


“What do we know about rare disease such as Neurodegeneration associated with iron deposition in the brain (NBIA). From bench to patient.” M.R. Wieckowski

My visit ended with a meeting with Małgorzata Pucułek, the director of the Gen. J. Bem High School and dr. Maciej Cwyl, the President of the NBIA Poland Association.

Our MitoLab team at the Free Radicals in Biology, Medicine, Sport and Nutrition conference in Gdańsk

UE Horizon RIA grant for our Laboratory

PAS GRAS scientific consortium, whose only Polish member is the Nencki Institute, is the winner of the European Commission's "Staying healthy" competition under the HORIZON-Research and Innovation Actions (RIA) program. 

The coordinator of PasGras activities in Poland is Prof. Mariusz Więckowski from the MitoLab

Research at the Nencki Institute will be carried out by 3 research teams led by: Prof. Mariusz Więckowski (Laboratory of Mitochondrial Biology and Metabolism), Prof. Agnieszka Dobrzyn (Laboratory of Cell Signaling and Metabolic Disorders) and Dr. Grzegorz Sumara (Laboratory of Metabolic Diseases).   

The project is focused on de-risking metabolic, environmental and behavioral determinants of obesity in children, adolescents and young adults. The PAS GRAS consortium will be centered on overweight/obese children, adolescents and young adults with the main objective of reversing obesity and preventing later-life comorbidities. It will be determined how the lifestyle (diet, sedentary behaviours and physical activity), mental health, social/family factors, environment, interact with each person's intrinsic psychological, genetic and metabolic characteristics. PAS GRAS will also fill critical gaps in obesity diagnosis and prognosis and food/nutrition literacy, as well as will provide a blueprint for a healthier population.

The unique multi- and interdisciplinary PAS GRAS consortium led by Prof. Paulo Oliviera from University of Coimbra consists of 11 European Universities and Research Institutions as well as non-Academic partners: European Society for Clinical Investigation (Holand); Portuguese Diabetes Association (APDP); civil association AGDCentro Gymnastics Association (Portugal) and biomedical company Mediagnost GmbH (Germany).

PAS GRAS is one of the 6 projects funded under UE Horizon RIA Program, budget of the PAS GRAS project – 9,5 mln EUR. 

Research collaboration with PACS2 Research Foundation 

It is my great pleasure to announce that we've entered research collaboration with the PACS2 Research Foundation, which unites patients affected by ultra-rare genetic disease caused by autosomal dominant mutation in PACS2 gene that leads to developmental and epileptic encephalopathy (DEEs).


At the Nencki Institute the study will be conducted by our MitoLab team as well as by the team from the Laboratory of Cell Signalling and Metabolic Disorders headed by Prof. Agnieszka Dobrzyn.

  A coordinated by me this collaborative research will contribute to a better understanding of the pathomechanism of this disease by filling the knowledge gaps regarding the impact of mutation in PACS2 gene on cellular metabolism.

Second bilateral Conference of the Nencki Institute and the Institute of Physiology of the Academy of Sciences of the Czech Republic

On October 11, the 2nd Conference of the Nencki Institute and the Institute of Physiology of the Academy of Sciences of the Czech Republic (IPHYS) was held at the Nencki Institute, coordinated by Prof. Mariusz Wieckowski and Prof. Adam Szewczyk from the Nencki Institute. 

The topics of the conference focused on metabolism and neurobiology. The meeting aimed to establish new contacts between group leaders and create a platform for further collaboration. The conference included 14 presentations by participants from both institutes. Researchers from the Czech Republic also had the opportunity to visit laboratories at the Nencki Institute.

Grant COST 

for 

Prof. Mariusz Wieckowski

The consortium whose member is prof. Mariusz Wieckowski from the Laboratory of Mitochondrial Biology and Metabolism is among the winners of the COST action - acronym PRESTO „P2X receptors as a therapeutic opportunity”

Prof. Wieckowski was appointed by Minister of Education and Science to represent Poland in the “PRESTO” COST Programme. The project is led by dr. Elena Adinolfi from the University of Ferrara. Consortium includes members from 20 different COST countries and two international partners from Brazil and Tunisia.

Ines Simoes received 

PhD degree

It is with great satisfaction we announce that Ines Simoes (ESR 1) from our laboratory was proclaimed Doctor in Biological Sciences. 

The objectives of her PhD, "Effects of Western diet in the development and progression of Non-alcoholic fatty liver disease", were to investigate the importance of mitochondria and peroxisomes in the development of NAFLD.

Congratulations to Dr. Inês Simoes for achieving this incredible milestone, and we wish you the best for the next chapter of your professional life!

Prof. Mariusz Wieckowski, the head of the Laboratory of Mitochondrial Biology and Metabolism at Nencki Institute, has been elected the councilor of the European Society for Clinical Investigation (ESCI) for the time frame of 2022-2024 starting officially in May 2022. The ESCI Council consists of 9-10 European councilors, chosen during and by the Annual Business Meeting of the Society.

The European Society for Clinical Investigation was established in 1967 as a pan-European Society to integrate clinicians and fundamental scientists with a genuine interest in uncovering the mechanisms involved in the pathophysiology of human disease. The objectives of the Society are the advancement of medical practice through science; the cultivation of clinical research by the methods of the natural sciences; the correlation of science with the art of medical practice; the fostering of high standards of ethical practice and investigation and the diffusion of a spirit of fraternity and international cooperation among and through its members. Society provides also a forum for discussion, debate and meeting colleagues in order to advance the science of clinical investigation. The term ‘clinical investigation’ is interpreted widely from bench to bedside including animal studies relevant to humans in health or disease.

Collaboration Agreement WITH NBIA Association Poland signed

Recently we've entered research collaboration with NBIA Association Poland, which unites patients affected by a rare genetic disease characterized by excessive brain iron accumulation (NBIA - neurodegeneration with brain iron accumulation).

The research that will be conducted in our Laboratory (in a close collaboration with the Laboratory of Cell Signalling and Metabolic Disorders headed by Prof. Agnieszka Dobrzyn also from Nencki Institute) will contribute to a better understanding of the pathomechanisms of NBIA disease most likely related to the alterations in lipid metabolism and mitochondrial dysfunction.
