Influence of adjuvant-active peptidoglycan monomer on specific T cell responses in mice.

Peptidoglycan monomer (PGM) originating from Brevibacterium divaricatum is a non-toxic, non-pyrogenic, water-soluble immunostimulator. It potentiates humoral immune response to ovalbumin (OVA) in mice upregulating both immunoglobulin (IgG) 1 and IgG2a antibody subclasses. This study concerns the influence of PGM on T cell activation and cytokine networks in response to OVA.
