Our research team participates in a study identifying betaine as a key component of breast milk capable of protecting against obesity in children.

In line with our affiliation to Institut de Recerca Sant Joan de Déu (IRSJD), we participated in a study published recently in Science Translational Medicine (DOI: 10.1126/scitranslmed.abb0322), the prestigious journal from the Science group. This research, led by Dr. Carles Lerin at IRSJD, identified an inverse relationship between maternal breast milk betaine content and infant growth, and it was demonstrated that  maternal betaine supplementation during lactation induced a transient increase in offspring intestinal Akkermansia abundance, and reduced early weight gain. Furthermore, it was shown that maternal betaine supplementation decreased adiposity and improved glucose metabolism throughout adulthood, demonstrating a link between breast milk betaine content and long-term metabolic health. Our participation in this study is a follow up of  our long standing research on the molecular basis of the healthy properties of breastfeeding.

The “Institut de Recerca Sant Joan de Déu” is appointed as a CERCA research center.

The "Institut de Recerca Sant Joan de Déu" (IRSJD) has been recognized by the Board of Trustees of the Institution of the Research Centers of Catalonia (CERCA) as a CERCA center. This  implies the recognition of the frontier biomedical research developed at IRSJD and oriented to the improvement of quality of life in children and adults. The CERCA recognition implies entering the Catalan research structure, as a top quality research center showing efficient management, and will allow access to additional funds to develop scientific activities.

Our research team has been part of IRSJD for a few years, which has enhanced our translational research in metabolism and endocrinology in collaboration with clinics at Sant Joan de Déu hospital. Examples of our translational research in pediatrics follow:

The Instituto de Salud Carlos III funds a research project led by Dr. Marta Giralt, in coordination with Dr. Pere Domingo from Hospital de la Santa Creu i Sant Pau, to investigate the abnormal body weight increase in HIV patients under integrase inhibitor-based drug treatments.


The  Integrase Strand Transfer Inhibitor (INSTI) antiretrovirals are  among the last generation drugs to treat HIV-infected patients. Recent data indicate that these patients show abnormally increased adiposity after treatment. Thus, the HIV infection and global obesity epidemics meet to confer to HIV patients increased metabolic and cardiovascular comorbidities.The coordinated research projects  will assess the molecular and cellular basis of such phenomenon and will identify potential targets of preventive intervention.

Our research group publishes the discovery of a new mechanism for regulating the metabolism of brown adipose tissue through the hormonal system kallikrein-kinin system in Nature Communications.


That system, in which bradykinin is a main actor, has been traditionally associated with the physiology of the renal and cardiovascular systems and processes of inflammation and pain. Our study, led by Dr.M.Peyrou, Juan de la Cierva researcher at our lab, reports that the kallikrein-kinin system acts as mechanism of molecular self-control of brown and beige adipose tissue thermogenic activation, and could help prevent the harmful effects of excessive activation of brown adipose tissue occurring in some pathological conditions such as cachexia or recovery from severe burns.The full article is accessible at:   https://rdcu.be/b3Ud4
