|
Structure |
heteropolysaccharide composed of galactose, arabinose, glucose, rhamnose and galacturonic acid in the molar ratio 1:0.89:0.13:0.89:0.38 |

Preparation |
A. rupestris L. powder was water-extracted, ethanol-precipitated, deproteinized, dialyzed to obtain crude polysaccharide |
|
Function |
Type: plant-derived vaccine adjuvant. Induces Th1-biased immune profile. CARP-2 stimulates the immune response by engaging the TLR4 pathway, triggering the activation of NF-?B and MAPK pathways and upregulating CD40 and CD86, This activation leads to the production of pro-inflammatory cytokines, including TNF-? and IL-6, which in turn activate dendritic cells and other innate immune cells, ultimately shaping the adaptive response. The production of TNF-? and IL-6 also promotes the activation of T cells |
