Expression of Neu5Acα2,3Gal and Neu5Acα2,6Gal on the nasal mucosa of patients with chronic rhinosinusitis and its possible effect on bacterial biofilm formation

Expression of MAL-II binding (most probable Neu5Acα2,3Gal) and SNA binding (Neu5Acα2,6Gal) were up-regulated in inflamed nasal mucosa, and the increased expression of them may contribute to bacterial biofilm formation which deserved a further investigation.
