ELLIIT tech talks – Digital twins (Swedish)

Uncategorised Posted on Fri, November 25, 2022 09:00:00

What exactly are digital twins, and how can we use them in the healthcare of the future? Gunnar Cedersund explains how it works. How can we make a digital model of ourselves and test different forms of treatment on our personal artificial twin before the treatment is actually performed.

Brain modelling in New York

Uncategorised Posted on Mon, November 21, 2022 09:00:00

Earlier this autumn Gunnar, Malin, and Henrik traveled to New York to meet several collaborators at SUNY Downstate Health Science University, including Henriks co-supervisor, Salvador Dura-Bernal, and the group of Willam Lytton. We discussed modelling, neuronal networks, synaptic plasticity, future brain modelling projects, and explored their work-environment. This was very interesting for Henrik since he will spend one year in New York during his PhD. In the end of the visit Gunnar also gave a lecture presenting our research at Linköping University. Malin and Gunnar also visited other collaborators in New York, and Malin helped out during a clinical trial.

It was an educational trip and great stay! We would like to thank the Dura-Bernal lab, Neurosim lab, and many other for their great hospitality and nice discussions.

VPH News Letter – Dancing digital twins

Uncategorised Posted on Mon, October 17, 2022 09:00:00

The opening ceremony of the Virtual Physiological Human (VPH) conference was something special, it featured a lecture-performance with our physiologically based dancing digital twins. The VPH Institute has now published a news letter were you can read more about the development of the digital twins for the past 20 years, and more about the future visions for using them within biomedical teaching and patient-centric care.

ICSB 2022

Uncategorised Posted on Mon, October 10, 2022 09:59:46

The 21st International Conference on Systems Biology (ICSB 2022) was held in Berlin, Germany, these past few days. We had a great time there and had the opportunity to meet great people, take part in interesting discussions, and see some of Berlin. During the conference, we presented several posters and gave some talks (summarized below). We would like to extend our thanks to the ICSB committee for a well-organized conference. Until next time, from the ISB group.

The full program can be found here:, and down below is a summary of our contributions.

Best poster prize at International Study Group for Systems Biology (ISGSB) 2022 conference

Uncategorised Posted on Tue, October 04, 2022 11:55:23

We recently attended the International Study Group for Systems Biology (ISGSB) 2022 conference where we gave two talks. Our first talk was given by Gunnar Cedersund and was on how we can use M4-models and digital twin tools to help patients on their health journey throughout various aspects of their lives. The second talk was given by Nicolas Sundqvist and was on our efforts to develop an interconnected multi-level mechanistic model of the human brain. The conference was a success as we partook in interesting discussions and offered our contributions to the ISGSB community. On another fun note, our poster designed and presented by Nicolas Sundqvist was voted joint best poster of the conference. We are looking forward to the next iteration of the ISGSB conference.

New Article: Digital twin predicting diet response before and after long-term fasting

Uncategorised Posted on Mon, September 26, 2022 14:30:55

Read our new article published in PLoS Computational Biology!

You find the full link here:

Silfvergren O, Simonsson C, Ekstedt M, Lundberg P, Gennemark P, Cedersund G. Digital twin predicting diet response before and after long-term fasting. PLoS Comput Biol. 2022 Sep 12;18(9):e1010469. doi: 10.1371/journal.pcbi.1010469.


“Fasting and diet are central components of prevention against cardiovascular disease. Unfortunately, there is little consensus regarding which diet schemes are optimal. This is partially because different clinical studies contribute with different non-connected pieces of knowledge, which have not been fully integrated into a useful and interconnected big picture. In principle, mathematical models describing meal responses could be used for such an integration. However, today’s models still lack critical mechanisms, such as protein metabolism and a dynamic glycogen regulation. Herein, we present a) a new expanded model structure including these mechanisms; b) a set of parameters which can simultaneously describe a wide array of complementary estimation data, in both healthy and diabetic populations; c) a personalisation-script, which allows these generic parameters to be tuned to an individual/sub-population, using demographics (age, weight, height, diabetes status) and historic metabolic data. We exemplify how this personalisation can be used to predict new independent data, including a new clinical study, where a qualitatively new prediction is validated: that an oral protein tolerance test gives a clear response in plasma glucose, after, but not before, a 48h fasting period. Our combined model, parameters, and fitting script lay the foundation for an offline digital twin.”
