Abstract:
A cancer diagnostic method that comprises the steps: (a) Providing a sample containing antibodies from a subject suspected of having cancer; (b) Incubating the sample with Gb5 and one or more of Globo H, Bb2, Bb3 and Bb4 to allow binding of the antibodies in the sample to the Gb5 and the Globo H, Bb2, Bb3 and Bb4; (c) Measuring the amount of the GB-5-bound antibodies and the amount of the Globo H-bound, Bb2-bound, Bb3-bound and Bb4-bound antibodies; (d) Determining whether the subject has the cancer based on the amounts of Gb5-bound antibodies and the Globo H-bound, Bb2-bound, Bb3-bound and Bb4-bound antibodies; The cancer is Globo H-positive and GB5-positive; and a higher ratio of the amount of Globo H-bound, Bb2-bound, Bb3-bound and Bb4-bound antibodies to the amount of Gb5-bound antibodies compared to a cancer-free subject indicates the subject has cancer. The cancer can be breast cancer, skin cancer, liver cancer, prostate cancer, ovary cancer, colon cancer, stomach cancer or pancreas cancer.
Abstract:
HUMAN INKT CELL ACTIVATION USING GLYCOLIPIDS Glycosphingolipids (GS Ls) compositions and methods for iNKT-independent induction of chemokines are disclosed.
Abstract:
Glycosphingolipids (GSLs) bearing α-glucose (α-Glc) that preferentially stimulate human invariant NKT (iNKT) cells are provided. GSLs with α-glucose (α-Glc) that exhibit stronger induction in humans (but weaker in mice) of cytokines and chemokines and expansion and/or activation of immune cells than those with α-galactose (α-Gal) are disclosed. GSLs bearing α-glucose (α-Glc) and derivatives of α-Glc with F at the 4 and/or 6 positions are provided. Methods for iNKT-independent induction of chemokines by the GSL with α-Glc and derivatives thereof are disclosed. Methods for immune stimulation in humans using GSLs with α-Glc and derivatives thereof are provided.
Abstract:
An immune composition containing Globo H or its fragment (e.g., SSEA3) and an adjuvant, e.g., a -GalCer, for eliciting immune responses against Globo H or its fragment and uses thereof in cancer treatment. Also disclosed is a method of treating cancer by inhibiting the activity of one of FUT1 and FUT2, both of which involve in Globo H biosynthesis.
