quillaja saponaria/免疫刺激剂

A novel antigen carrier has been formulated on the basis of a cucumarioside-A2-2 triterpene glycoside (CD) complex with cholesterol and monogalactosyldiacylglycerol from Ahnfeltia tobuchiensis (MGDG(At)) and Ulva fenestrate (MGDG(Uf)). Morphological and immunostimulative characteristics of the

ISCOMs have received much attention as vaccine adjuvants due to their immunostimulatory effects. They are colloidal particles typically comprised of phospholipids, cholesterol and Quil A, a crude mixture of saponins extracted from the bark of Quillaja saponaria Molina. We have previously shown that

Five saponins purified from the leaves of three Ilex species (saponins 1 and 2 from I. dumosa; saponin 3 from I. argentina; saponin 4 from I. paraguariensis) and from Passiflora alata (saponin 5) were evaluated for their in vitro haemolytic activity and in vivo immunostimulatory ability in a mouse

QS-21 is one of the most promising new adjuvants for immune response potentiation and dose-sparing in vaccine therapy given its exceedingly high level of potency and its favorable toxicity profile. Melanoma, breast cancer, small cell lung cancer, prostate cancer, HIV-1, and malaria are among the

QS-21 is a purified immunological adjuvant derived from a natural source, the bark of the tree Quillaja saponaria. It is a water soluble triterpene glycoside with amphiphilic character that can be mixed with a soluble antigen in a fully soluble vaccine formulation or combined with emulsion or

We have prepared a number of saponin-based vaccine adjuvant candidates. These unnatural saponins have a different terminal-functionalized side chain incorporated into the glucuronic acid unit that is attached to a triterpenoid core at its C3 position. The semisynthetic saponin adjuvants have shown
