Galectins in intestinal inflammation: Galectin-1 expression delineates response to treatment in celiac disease patients
Galectins, a family of animal lectins characterized by their affinity for N-acetyllactosamine-enriched glycoconjugates, modulate several immune cell processes shaping the course of innate and adaptive immune responses. Through interaction with a wide range of glycosylated receptors bearing complex b...

In addition, we present new data highlighting the regulated expression of galectin-1 (Gal-1), a proto-type member of the galectin family, during intestinal inflammation in untreated and treated CeD patients. Our results unveil a substantial upregulation of Gal-1 accompanying the anti-inflammatory and tolerogenic response associated with gluten-free diet in CeD patients, suggesting a major role of this lectin in favoring resolution of inflammation and restoration of mucosal homeostasis. Thus, a coordinated network of galectins and their glycosylated ligands, exerting either anti-inflammatory or proinflammatory responses, may influence the interplay between intestinal epithelial cells and the highly specialized gut immune system in physiologic and pathologic settings. © 2018 Sundblad, Quintar, Morosi, Niveloni, Cabanne, Smecuol, Mauriño, Mariño, Bai, Maldonado and Rabinovich. 2018 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_16643224_v9_nMAR_p_Sundblad http://hdl.handle.net/20.500.12110/paper_16643224_v9_nMAR_p_Sundblad |

Galectins, a family of animal lectins characterized by their affinity for N-acetyllactosamine-enriched glycoconjugates, modulate several immune cell processes shaping the course of innate and adaptive immune responses.
