  2. Toll-like Receptor (TLR)
  3. PSMα3

PSMα3 is a peptide for manipulating DCs to become tolerogenic for DC vaccination strategies. PSMα3 penetrates and modulates human monocyte-derived DCs by altering the TLR2- or TLR4-induced maturation, inhibiting pro- and anti-inflammatory cytokine production and reducing antigen uptake. PSMα3 is an important toxin released by the most virulent strains of methicillin-resistant Staphylococcus aureus (MRSA).

Description

PSMα3 is a peptide for manipulating DCs to become tolerogenic for DC vaccination strategies. PSMα3 penetrates and modulates human monocyte-derived DCs by altering the TLR2- or TLR4-induced maturation, inhibiting pro- and anti-inflammatory cytokine production and reducing antigen uptake. PSMα3 is an important toxin released by the most virulent strains of methicillin-resistant Staphylococcus aureus (MRSA)[1][2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
