Recently, scientific interest is shifting from live bacteria to defined bacteria-derived biologically active molecules. Their greatest advantage over probiotics is the defined structure and the effect independent of the viability status of the bacteria. Here, we aim to characterize Bifidobacterium adolescentis CCDM 368 surface antigens that include polysaccharides (PSs), lip-oteichoic acids (LTAs), and peptidoglycan (PG). Among them, Bad368.1 PS was observed to modulate OVA-induced cytokine production in cells isolated from OVA-sensitized mice by increasing the production of Th1-related IFN-gamma and inhibition of Th2-related IL-5 and IL-13 cytokines (in vitro). Moreover, Bad368.1 PS (BAP1) is efficiently engulfed and transferred between epithelial and dendritic cells. Therefore, we propose that the Bad368.1 PS (BAP1) can be used for the modulation of allergic diseases in humans. Structural studies revealed that Bad368.1 PS has an average molecular mass of approximately 9,99 x 106 Da and it consists of glucose, galactose, and rhamnose residues that are creating the following repeating unit: [-> 2)-beta-D-Glcp-(1> 3)-beta-L-Rhap-(1> 4)-beta-D-Glcp-(1> 3)-alpha-L-Rhap-(1> 4)-beta-D-Glcp-(1> 3)-alpha-D-Galp-(1> ]n Workplace Institute of Microbiology Contact Eliška Spurná, eliska.spurna@biomed.cas.cz, Tel.: 241 062 231 Year of Publishing 2024 Electronic address https://www.sciencedirect.com/science/article/pii/S0144861723004459?pes=vor
