D-Galacto-D-mannan
Based on 1 Customer Validation
D-Galacto-D-mannan (Carob galactomannan) is an orally active Dectin-2 agonist. D-Galacto-D-mannan exerts antioxidant activity against hydroxyl radical generation. D-Galacto-D-mannan activates Dectin-2 to trigger downstream signaling pathways, promote the expression of immunoregulatory molecules, coordinate innate and adaptive immune responses, and inhibit excessive inflammatory responses by upregulating the expression of Sirtuin 1. When used as a vaccine adjuvant, D-Galacto-D-mannan induces cellular and humoral immune responses, promotes IFNγ secretion, increases antibody levels and virus neutralization titers, and elevates the levels of immunoglobulin G and A. D-Galacto-D-mannan can serve as an adjuvant for foot-and-mouth disease vaccines, enhance the vaccine-mediated ability of hosts to defend against viral infection in mice, and reduce local side effects at the inoculation site in pigs. D-Galacto-D-mannan can be used in the research of inflammatory and immune diseases, such as foot-and-mouth disease.

Biological Activity
|
Dectin-2 |
D-Galacto-D-mannan (0.625-5 μg/mL; 18 h (co-treated with FMDV antigen)), when co-treated with FMDV antigen for 18 h, significantly enhances IFNγ secretion in murine PECs and porcine PBMCs, indicating potent induction of innate and cellular immune responses[1].

D-Galacto-D-mannan (1 mg/dose per pig; i.m.; booster immunization at 28 days after primary immunization) induces significantly stronger early, intermediate and long-term humoral immune responses in FMDV-seronegative Landrace pigs, with superior safety, as a component of the bivalent foot-and-mouth disease vaccine[1].
