VIDEO ABSTRACT. Given that phagocytic cells are main players of the host immune response, we studied the interaction of bifidobacteria with monocytic THP-1 cells in nonopsonic conditions. Association/internalization, cell response (expression of HLA-DR and TLR2), M1/M2 macrophage polarization and colocalization of micro-organisms with Lysotracker or transferrin were evaluated. Screening with eight Bifidobacterium strains showed two patterns of interactions with THP-1 cells high and low association and phagocytosis. Two strains with
