Molecular control of immune cell activation in health & disease – 24-28th August 2023

Members of our group attended the 4th International Immunology Workshop in Kabelvåg, Norway. We presented results on PLGA nanoparticle immunomodulation, including mechanistic and effect duration studies, in HLA transgenic mouse models of celiac disease and narcolepsy with cataplexy.

ABC7: Autoimmunity, B cells and Complement – 14-16 June 2023

Group members attended the International Immunology Summer School in Tallinn, Estonia. At the meeting, Tobias spoke about Antigen-specific Immune Tolerance Induction in Autoimmune Diseases, while Eva’s abstract had been selected for oral presentation.

49th Annual Meeting and Summer School of the Scandinavian Society for Immunology – 4-7 June 2023

Our group attended the 49th SSI meeting in Turku, Finland. During the conference, Eva presented brand new results demonstrating antigen-specific immune tolerance induction by PLGA nanoparticles in a mouse model of narcolepsy type 1.

Congratulations Vicky on your PhD defence on May 12, 2023!

Victoria  Ortin  Piqueras defended her PhD thesis entitled "Development of an in vivo intestinal permeability test to refine the use of mouse models in research’’.

A novel autoantigen in narcolepsy type 1 identified

Our group and collaborators have identified two influenza A (H1N1) virus peptides against which pediatric narcolepsy type 1 patients show strong T cell reactions. These peptides resemble human protein fragments, in particular a peptide from protein-O-mannosyl transferase 1, and due to T cell cross-reactivity may cause an immune response against the body’s own neuronal cells. Our study supports the concept that influenza A (H1N1) virus peptides can trigger an autoimmune reaction in genetically predisposed individuals, that results in the onset of narcolepsy with cataplexy.

Celiac disease might be cured by restoring immune tolerance to gliadin

Our group co-developed and tested PLGA nanoparticles containing gliadin for the immunomodulatory treatment of celiac disease in collaboration with industry.
