Different preclinical studies revealed that this vaccine induced high antibody responses in the absence of additional adjuvant in mice, rabbits, and monkeys without inducing A?-specific T cells. Immunization with CAD106 prevented amyloid cortical plaque deposition in both.
6/1/2018 · Key Figure: Proposed Mechanism of Action for QS-21 and Related Saponin-Derived Adjuvants. Quillaja saponin ad ju vants, like QS-21, act on both T cells and dendritic cells (DCs). T cell: The aldehyde group on QS-21forms an imine with an ?-amino group from a T cell surface receptor, most likely CD2, delivering a costimulatory signal to the T cell.
1/15/2016 · Despite the apparent success of QS-21 as a vaccine adjuvant, the mechanism of action is largely unknown. It has been described to stimulate the innate immune response in mice by increasing natural killer cell activity and in vitro by propagating the release of inflammatory cytokines ( 43 ).
Results: Insights into the mechanism of action of QS-21 can be summarized as follows: 1) in vivo stimulation of Th2 humoral and Th1 cell-mediated immune responses through action on antigen …
