Lewis X trisaccharide
Based on 1 Customer Validation
Lewis X trisaccharide (Lewis X, Lex) is a potent TH2 regulator, antagonizes LPS-induced IL-12 immune expression. Lewis X trisaccharide is a human histo-blood group antigen, plays an key role in cell-cell adhesion, and servers as a tumor marker. Lewis X trisaccharide is highly expressed in the outer membrane of the parasite, can be used for the immunology research of schistosomiasis.

Lewis X trisaccharide-BSA (25 μg/mL; 30 min; before LPS stimulation of 10 ng/mL for 4 h) IL-12p40 and suppresses IL-12p70 protein expression induced by Lipopolysaccharide (LPS, HY-D1056)[1].
Lewis X trisaccharide (2 μM; 30 min; before LPS stimulation of 10 ng/mL for 2 h) decreases nuclear NF-κB concentration in mice bone marrow derived dendritic cells (BDDCs)[1].
Lewis X trisaccharide-BSA (25 μg/mL; 48 h) or Lewis X trisaccharide (5 μg/mL; 48 h) plus ovalbumin (OVA, 25 μg/mL) increases cytokines (IL-4, IL-13, and INF-γ) level in mice splenocytes[1].
Lewis X trisaccharide-containing glycoconjugates stimulates B cells to proliferate and to produce factors that down-regulates the TH1 immune response and up-regulates the TH2 immune response[2].

Animal Model:Mice (BALB/c, IL-12 deficient on a BALB/c background, TLR4-defective C3H/hej, or TLR4-wild type C3H/HeOuj mice) (6-8 weeks old)[1]
-
Dosage:5 μg, combinded with 50 μg ovalbumin
-
Administration:Subcutaneous injection; once a week for 2 weeks
-
Result:In C3H mice, coupled with BSA (LeX-BSA) and elicited higher levels of specific IgE and IgG1, but not IgG2a, which were associated with increased levels of splenic TH2 cytokines when compared with those seen in BSA-sensitized mice.
In BALB/c mice, induced by ovalbumin, significantly increased levels of specific IgE, resulted IgG2a antibodies concomitant with reduced levels of serum IL-12p70.
In IL-12-deficient BALB/c mice, attenuated the downward trend of the above indicators.
