Surface proteins of [i]Propionibacterium freudenreichii[/i] are involved in its anti-inflammatory properties.

Propionibacterium freudenreichii is a food grade bacterium consumed both in cheeses and in probiotic preparations. Its promising immunomodulatory potential largely relies on the presence of specific and strain-dependent surface compounds. The CIRM BIA 129 strain was selected for immunomodulatory properties, its surfaceome deciphered using an integrative approach. Surface Layer Associated Proteins (SLAPs) are involved in the anti-inflammatory properties,
