As butyrate seems to be the short-chain fatty acid with more prominent activity in both reducing IL-6 secretion from LPS-treated U373 cells and upregulation of MAP2 gene in neuroblastoma cells, two other strains, MRx0071 and MRx1342, known to be butyrate producers (Yuille et al., 2018), were tested in the same assays conducted above. The gene discussed is MAP2; the disease is neuroblastoma.
