TASTY trial: protocol for a study on the triad of nutrition, intestinal microbi...
Charneca, Sofia; Hernando, Ana; Almada-Correia, Inês; Polido-Pereira, Joaquim; Vieira, Adriana; Sousa, Joana; Almeida, Ana Santos; Motta, CarlaBackground: The gut microbiota has been implicated in the onset and progression of Rheumatoid Arthritis (RA). It has been proposed that gut dysbiosis impairs gut barrier function, leading to alterations in mucosal integrity and immunity. This disruption allows bacterial translocation, contributing to the perpetuation of the inflammatory process. Since diet is recognised as a key environmental factor influencing...

Alterations in mucosa branched N-glycans lead to dysbiosis and downregulation o...
Rodrigues, Cláudia S.; Gaifem, Joana; Pereira, Márcia S.; Alves, Maria Francisca; Silva, Mariana; Padrão, Nuno; Cavadas, BrunoThe perturbation of the symbiotic relationship between microbes and intestinal immune system contributes to gut inflammation and Inflammatory Bowel Disease (IBD) development. The host mucosa glycans (glycocalyx) creates a major biological interface between gut microorganisms and host immunity that remains ill-defined. Glycans are essential players in IBD immunopathogenesis, even years before disease onset. Howe...
Akkermansia muciniphila and Parabacteroides distasonis synergistically protect ...
Gaifem, Joana; Mendes-Frias, Ana; Wolter, Mathis; Steimle, Alex; Garzón, Maria Jose; Ubeda, Carles; Nobre, Clarisse; González, Abigail; Pinho, Salomé S.The contribution of the gut microbiome to the balance between homeostasis and inflammation is widely known. Nevertheless, the etiology of inflammatory bowel disease, which is known to be influenced by genetics, immune response, and environmental cues, remains unclear. Unlocking novel players involved in the dictation of a protective gut, namely, in the microbiota component, is therefore crucial to develop novel...
Metabolic control of T cell immune response through glycans in inflammatory bow...
Dias, Ana M.; Correia, Alexandra; Pereira, Márcia S.; Almeida, Catarina R.; Alves, Inês; Pinto, Vanda; Catarino, Telmo A.; Mendes, NunoMucosal T lymphocytes from patients with ulcerative colitis (UC) were previously shown to display a deficiency in branched N-glycosylation associated with disease severity. However, whether this glycosylation pathway shapes the course of the T cell response constituting a targeted-specific mechanism in UC remains largely unknown. In this study, we demonstrated that metabolic supplementation of ex vivo mucosal T...
