Propionibacterium acnes Bacterial Cell Wall (P. acnes Cell Wall)

The bacterial cell wall of *Propionibacterium acnes* (now often referred to as *Cutibacterium acnes*) is a complex, multi-component structure that plays critical roles in maintaining cell shape, protecting against environmental stress, mediating host interactions, and contributing to pathogenicity. As a Gram-positive bacterium, its cell wall is thick and primarily composed of peptidoglycan interlaced with other polysaccharides and surface proteins. Key components include a specialized peptidoglycan network, unique polysaccharides containing N-acetylgalactosamine and N-acetylmannosamine derivatives, various glycosylated adhesin proteins anchored via LPXTG motifs (including immunogenic enzymes like sialidase), and it serves crucial roles in immune activation, biofilm formation, adherence, and pathogenicity.
