Bacteria in Fermented Food Signal the Human Immune System, Explaining Health Benefits (image) PLOS Share Print E-Mail Caption We found that D-phenyllactic acid is absorbed from lactic acid bacteria fermented food (e.g. Sauerkraut) and induces HCA3-dependent migration in human monocytes. Future studies need to address how HCA3 activation by lactic acid bacteria-derived metabolites modulates immune function and energy storage.
