Fig. 5.

NF-κB activation in PMA-differentiated THP-1 macrophages exposed to inactivated cells of Lactobacillus plantarum P5, Pediococcus lolii F7 and Lactobacillus reuterii D4 at a bacteria:macrophage ratio of 100:1 (black dots); 10:1 (grey dots); or 1:1 (white dots) for 24 h. NF-κB activation is presented as a fold increase over a non-stimulated condition and the selected LAB strains represent a low (P5), moderate (F7), and high (B4) NF-κB response in THP-1 macrophages. Data represent at least two biological replicates
