The acylated analogs of picroside-II were synthesized and tested for immune-adjuvant activity in the presence of weak antigen ovalbumin found to stimulate anti-OVA IgG titer, neutralizing antibody (IgG1 and IgG2a) titer as well as the production of soluble mediators of a Th1 response (IL-2 and IFN-γ) and Th2 response (IL-4) and proliferation of T lymphocytes sub-sets (CD4/CD8). Furthermore, these...
Adjuvants in vaccines are immune stimulants that play an important role in the induction of effective and appropriate immune responses to vaccine component. In search of a potent vaccine adjuvant, the water-soluble biopolymeric fraction BOS 2000 from Boswellia serrata was evaluated for desired activity. We investigated the ability of BOS 2000 to enhance HBsAg specific immune responses. The effect...
Alum has been in use since long as an adjuvant for vaccines. However, its use as a vaccine adjuvant offers limitation in supporting cell mediated response. Therefore, a new plant based product RLJ-NE-299A from Picrorhiza kurroa reported for its immunostimulatory activity, has been explored for its potential as an alternative adjuvant. In order to compare the adjuvant activity with alum, antigen-specific...
