| Abstract |
Probiotic lactic acid bacteria evoke immunomodulatory effects in the host; however, the reasons for the different effects of various species and strains remain to be elucidated. To clarify the critical immunomodulatory components and impact of exopolysaccharide (EPS) in Lactiplantibacillus plantarum, 11 types of L. plantarum strains were compared for the production of EPS, inflammatory cytokines, interleukin-6 and -12, and the anti-inflammatory cytokine, interleukin-10, from THP-1 differentiated dendritic cells. EPS in the fermented medium correlated with cytokine-inducing activities. L. plantarum JCM 1149, with the highest production of EPS, also induced interleukin-6, -10, and -12 among the 11 tested strains. Notably, the cytokine-producing activities overlapped with the protein fraction in gel filtration chromatography but not with EPS, which has been reported to exert immunomodulatory effects. The 41 kDa protein that coexisted with EPS was purified as a major active component and identified as glyceraldehyde 3-phosphate dehydrogenase (GAPDH), a known moonlighting protein. GAPDH secretion was reduced when EPS synthesis inhibitors were added to the culture medium. RNA sequencing of GAPDH-treated THP-1 cells revealed an up-regulation in the expression of genes involved in transcriptional regulation, cell surface receptor signalling, immune response, and matrix components. Here, we report, to our knowledge for the first time, that the cell surface-associated L. plantarum GAPDH plays a crucial role in cytokine production in THP-1 cells, but EPS with less activity may help GAPDH secretion. |
