A study led by the Diabetes and Associated Metabolic Diseases (DIAMET) group at the Institut de Recerca Biomèdica Catalunya Sud (IRB CatSud, formerly IISPV) shows that liver fibrosis and type 2 diabetes significantly modify the hormonal response after eating in people with fatty liver associated with metabolic dysfunction (MASLD). The research, published in the Journal of Physiology and Biochemistry, examines how both conditions affect the secretion of essential hormones for glucose control—such as glucagon and the incretins (GLP‑1, GLP‑2 and GIP)—after a standardized meal.

The results show that liver fibrosis is the most important factor influencing the increase in GLP‑1 levels, both in fasting conditions and after the meal, regardless of whether the patient has diabetes. In addition, when liver fibrosis and type 2 diabetes occur together, hormonal changes become stronger, suggesting a synergistic effect between both conditions. Type 2 diabetes is also linked to the loss of the normal suppression of glucagon after eating, a key process to keep blood glucose within healthy ranges.

These findings reinforce the idea that a fibrotic liver is not a passive organ, but plays an active role in metabolic dysregulation. Fibrosis not only reflects past damage but also contributes to generating new hormonal alterations. Understanding these changes is essential to improve clinical assessment and move towards more personalised treatments for MASLD.

With the growing prevalence of MASLD and type 2 diabetes, understanding how these conditions interact at the hormonal level is crucial to improve early diagnosis and optimise treatments based on the incretin–glucagon axis. The study provides evidence that can help identify subgroups of patients who may benefit from more specific therapeutic approaches, with a direct impact on clinical practice.

Overall, the results confirm that liver fibrosis is a central determinant of GLP‑1 levels, and that the coexistence of type 2 diabetes further intensifies these hormonal alterations. This knowledge highlights the need to design therapeutic strategies adapted to the metabolic and liver profile of each patient, especially in a context where both diseases are becoming increasingly common.

The study involved researchers from the Universitat Rovira i Virgili (URV), the Institut d’Investigacions Biomèdiques August Pi i Sunyer (IDIBAPS) – Hospital Clínic Barcelona, the research networks of the Instituto de Salud Carlos III (ISCIII) — the Centro de Investigación Biomédica en Red de Diabetes y Enfermedades Metabólicas Asociadas (CIBERDEM) and the Centro de Investigación Biomédica en Red de Enfermedades Hepáticas y Digestivas (CIBEREHD) — as well as the Hospital Universitari Joan XXIII (Tarragona).

This Thursday, 22 January at 4 p.m., Dr Carlos Castaño, a postdoctoral researcher, will take part in the CIBEROBN Webinars 2026 series with a presentation focused on an emerging topic in the field of host–microbiome interaction. His talk, titled “Isolation and Characterization of Circulating Bacterial Extracellular Vesicles: A Novel Approach to Understanding Host–Microbiome Interactions in Obesity”, will explain how bacterial extracellular vesicles found in the bloodstream may offer new tools to understand the molecular mechanisms that link the microbiome to obesity. This innovative approach opens the door to new research lines and possible diagnostic or therapeutic applications. Later, on 16 February at 4 p.m., the SEBBM group “Molecular Bases of Pathology”, coordinated by Dr Sonia Fernández‑Veledo, will organise another webinar dedicated to the neurobiology of eating behaviour. Researcher Roberta Haddad‑Tovolli (IDIBAPS) will give the lecture “Neuronal circuits underlying appetitive behaviors in the maternal brain and the programming of offspring health”. The session will explore how the neuronal circuits of the maternal brain regulate food‑related behaviours and how these processes may influence the long‑term health of the offspring.
In the coming months, the scientific community interested in biomedical research and the molecular basis of disease will have the opportunity to attend two high‑level online sessions led by experts in their fields.

The webinar is part of the growing interest in understanding how neurobiological and environmental factors during pregnancy and breastfeeding affect development and future health. Both webinars are an excellent opportunity to update knowledge, discover new research perspectives and connect with the specialised scientific community.
The initiative aims to raise public awareness of the importance of acquiring healthy lifestyle habits and supporting biomedical research carried out in the territory
The town councils of Perafort and Puigdelfí and of Els Garidells are organizing the 10th edition of the Solidarity Walk ‘Let’s Take a Step Against Diabetes’, which will take place next Sunday, November 23rd. This is a well-established event that returns this year full of symbolism and solidarity. This edition will be especially meaningful, as the 10 years of the walk coincide with the 20th anniversary of the Institut d’Investigació Sanitària Pere Virgili (IISPV), the center that will receive the funds raised during the event. Over these 10 editions, the organizing councils have managed to raise a total of €11,000, which has been used to support diabetes research projects carried out by the Institute.

The Solidarity Walk ‘Let’s Take a Step Against Diabetes’ aims to raise awareness among the population about the importance of adopting healthy lifestyle habits and to support biomedical research carried out in the region. All the funds raised will go to the Diabetes and Associated Metabolic Diseases Research Group (DIAMET) at IISPV, which focuses on finding new knowledge and strategies to improve the prevention, diagnosis, and treatment of diabetes and other metabolic diseases.

“The Perafort Town Council reaffirms its commitment to health, solidarity, and medical research through this initiative—values we consider essential for the well-being of our citizens. The funds are allocated to the IISPV to support research and scientific progress in this field,” said the mayor of Perafort, Joan Martí Pla i Pla. The Perafort Town Council thanks all the individuals and organizations involved and invites everyone to join this solidarity cause. Taking a step against diabetes is taking a step for everyone’s health.

There are different types of diabetes, but the most common are type 1 and type 2. Type 1 diabetes affects about 0.2% of the population in Spain, and around 10% of diagnosed cases are in young people and children. Type 2 diabetes affects between 6% and 14% of the population. This percentage depends on the age group considered, but the older the person, the higher the incidence.

The director of the IISPV, Joan Vendrell, explains that “diabetes is not visible, but it can be controlled with information and a healthy lifestyle. In this sense, events like the walk are very valuable, as they help raise awareness about the disease and its impact, and also promote the work we do. Moreover, they are an opportunity for people to contribute to the development of the various research projects underway at the Institute.”

With a registration fee of €5, participants will receive a commemorative T-shirt, enjoy breakfast and drinks in Els Garidells, and take part in a raffle of products offered by the event’s sponsors after the walk. Registration is open until November 21st, 2025, through the following link: https://serveis.iispv.cat/events/desena-caminada-contra-la-diabetis
