    • Carnitine palmitoyltransferase 1C negatively regulates the endocannabinoid hydrolase ABHD6 in mice, depending on nutritional status 

      Miralpeix Monclús, Cristina; Reguera, Ana Cristina; Fosch, Anna; Casas, Maria; Lillo, Jaume; Navarro, Gemma; Franco, Rafael; Casas, Josefina; Alexander, Stephen P.H.; Casals i Farré, Núria; Rodríguez-Rodríguez, Rosalía (British Journal of Pharmacology, 2021-01)
      Background and Purpose: The enzyme α/β‐hydrolase domain containing 6 (ABHD6), a new member of the endocannabinoid system, is a promising therapeutic target against neuronal‐related diseases. However, ...
    • Central ceramide-induced hypothalamic lipotoxicity and ER stress regulate energy balance 

      Contreras, Cristina; González-García, Ismael; Martínez-Sánchez, Noelia; Seoane-Collazo, Patricia; Jacas i Mateu, Jordi; Morgan, Donald A.; Serra, Dolors; Gallego, Rosalía; Gonzalez, Francisco; Casals i Farré, Núria; Nogueiras, Rubén; Rahmouni, Kamal; Diéguez, Carlos; López, Miguel (Cell Reports, 2014-10)
      Hypothalamic endoplasmic reticulum (ER) stress is a key mechanism leading to obesity. Here, we demonstrate that ceramides induce lipotoxicity and hypothalamic ER stress, leading to sympathetic inhibition, ...
    • Central regulation of brown fat thermogenesis in response to saturated or unsaturated long-chain fatty acids 

      Fosch Masllovet, Anna; Rodríguez García, Maria; Miralpeix , Cristina; Zagmutt, Sebastián; Larrañaga Fernandez, Maite; Reguera, Ana Cristina; Garcia-Chica, Jesus; Herrero, Laura; Serra, Dolors; Casals, Nuria; Rodriguez-Rodriguez, Rosalia (International Journal of Molecular Sciences, 2023)
      Sensing of long-chain fatty acids (LCFA) in the hypothalamus modulates energy balance, and its disruption leads to obesity. To date, the effects of saturated or unsaturated LCFA on hypothalamic-brown ...
    • CPT1C in the ventromedial nucleus of the hypothalamus is necessary for brown fat thermogenesis activation in obesity 

      Rodríguez-Rodríguez, Rosalía; Miralpeix Monclús, Cristina; Fosch, Anna; Pozo Ariza, Macarena; Calderón-Domínguez, María; Perpinyà, Xavier; Vellvehí, Miquel; López, Miguel; Herrero Rodríguez, Laura; Serra, Dolors; Casals i Farré, Núria (Molecular Metabolism, 2019-01)
      Objective: Carnitine palmitoyltransferase 1C (CPT1C) is implicated in central regulation of energy homeostasis. Our aim was to investigate whether CPT1C in the ventromedial nucleus of the hypothalamus ...
    • Ghrelin causes a decline in GABA release by reducing fatty acid oxidation in cortex 

      Mir, Joan Francesc; Zagmutt, Sebastián; Lichtenstein, Mathieu P.; García-Villoria, Judit; Weber, Minéia; Gracia, Ana; Fabriàs, Gemma; Casas, Josefina; López, Miguel; Casals i Farré, Núria; Ribes, Antònia; Suñol, Cristina; Herrero Rodríguez, Laura; Serra, Dolors (Springer Nature, 2018)
      Lipid metabolism, specifically fatty acid oxidation (FAO) mediated by carnitine palmitoyltransferase (CPT) 1A, has been described to be an important actor of ghrelin action in hypothalamus. However, it ...
    • Hypothalamic endocannabinoids in obesity: an old story with new challenges 

      Miralpeix Monclús, Cristina; Reguera, Ana Cristina; Fosch, Anna; Zagmutt, Sebastián; Casals i Farré, Núria; Cota, Daniela; Rodríguez-Rodríguez, Rosalía (Cellular and Molecular Life Sciences, 2021)
      The crucial role of the hypothalamus in the pathogenesis of obesity is widely recognized, while the precise molecular and cellular mechanisms involved are the focus of intense research. A disrupted ...
    • Hypothalamic endocannabinoids inversely correlate with the development of diet-induced obesity in male and female mice 

      Miralpeix Monclús, Cristina; Fosch, Anna; Casas, Josefina; Baena, Miguel; Herrero Rodríguez, Laura; Serra, Dolors; Rodríguez-Rodríguez, Rosalía; Casals i Farré, Núria (Journal of Lipid Research, 2019-07)
      The endocannabinoid (eCB) system regulates energy homeostasis and is linked to obesity development. However, the exact dynamic and regulation of eCBs in the hypothalamus during obesity progression remain ...
    • Hypothalamic regulation of obesity 

      Rodríguez-Rodríguez, Rosalía; Miralpeix Monclús, Cristina (International Journal of Molecular Sciences, 2021)
      Obesity has now reached pandemic proportions and represents a major socioeconomic and health problem in our societies. Up to now, obesity has been considered a medical issue only in high-income countries, ...
    • Targeting carnitine palmitoyltransferase 1 isoforms in the hypothalamus: a promising strategy to regulate energy balance 

      Rodríguez-Rodríguez, Rosalía; Fosch, Anna; Garcia-Chica, Jesús; Zagmutt, Sebastián; Casals Farré, Nuria (Journal of Neuroendocrinology, 2023)
      Tackling the growing incidence and prevalence of obesity urgently requires uncovering new molecular pathways with therapeutic potential. The brain, and in particular the hypothalamus, is a major integrator ...
