General description

Monophosphoryl lipid A (MPLA) is either extracted from bacterial lipid A or by chemical synthesis.
Vaccination is well-accepted as an effective method to prevent infections by mounting pathogen-specific immune responses prior to the infection. Usually, immunization with vaccine antigens alone is not able to induce robust or long-lasting immune responses — resulting in failure of protective immunity against infections. Thus, adjuvants are required to enhance cellular or humoral immune responses upon immunization. Because vaccine adjuvants using Lipid A have proven to be safe and effective in inducing Th-1 type immune responses to heterologous proteins in animal and human vaccines, Avanti developed Phosphorylated HexaAcyl Disaccharide (PHAD), the first fully synthetic monophosphoryl Lipid A available for use as an adjuvant in human vaccines.

Application

MPLA PHAD has been used:
  • as a component of cobalt porphyrin-phospholipid (Co-PoP) liposomes for the immunization of mice with membrane proximal external region (MPER) of the gp41 envelope protein
  • as an adjuvant along with dimethyldioctadecylammonium bromide(DDA) for C. muridarum recombinant membrane protein based multi-subunit vaccine
  • as toll-like receptor-4 (TLR4) agonist adjuvant for respiratory syncytial virus (RSV) fusion (F) protein FI-RSV vaccine

Biochem/physiol Actions

Monophosphoryl lipid A (MPLA) is a natural agonist for the toll-like receptor-4 (TLR4). It is useful as an adjuvant in immunization. MPLA is a safe prophylactic agent and has immunotherapeutic applications. MPLA used in vaccination improves B cell and T cell-mediated immunity.

Toll-like receptors (TLRs), a family of "pattern recognition receptors," bind microbial and host-derived molecules, leading to intracellular signaling and proinflammatory gene expression. TLR4 is unique in that ligand-mediated activation requires the co-receptor myeloid differentiation 2 (MD2) to initiate two signaling
