The present invention relates to compositions and methods for treating cancer. The invention makes use of peptides, nucleic acids encoding such peptides, and cells expressing such peptides, where the peptide comprises a tumor-associated carbohydrate antigen (TACA)-binding domain.

Glycan-dependent immunotherapeutic molecules

The present invention includes a novel method of treating or preventing a disease or disorder associated with low levels of branched N-glycans in a subject in need thereof, the method comprising administering to the subject an effective amount of a compound of the invention. In one embodiment, the subject is further administered at least one additional therapeutic agent.

Analogs of N-acetlyglucosamine and uses thereof

The invention provides the art with a powerful diagnostic method of distinguishing relapse-remitting MS subjects from progressive MS subjects, based on the measurement of serum concentrations of N-acetylglucosamine (GlcNAc,), for the first time enabling rapid diagnosis of the progressive form of MS. GlcNAc serum concentration can also be used to assess neurodegenerative status and MS progression in subjects suffering from MS or other neurological conditions. The methods of the invention also allow for the identification of new therapeutics for MS and other neurological conditions and also enables the personalized efficacy assessment of a potential therapy for an MS subject.

N-acetyl glucosamine as a biomarker of MS disease course

Contemplated compositions and methods are directed to prevent and/or treat various autoimmune diseases that are typically associated with glycan dysregulation, and especially autoimmune demyelinating diseases. Further especially contemplated aspects include animal models and systems for screening compounds to treat and/or prevent such diseases.

Methods and compositions for preventing and treating a disease related to glycan dysregulation

The invention relates to isolated complexes comprising one or more galectin associated with Mgat5 modified glycan or polylactosamine modified glycan, and isolated lectin-Mgt5 modified glycan lattice comprising an array of multivalent interactions among lectins, Mgat5 modified glycans, polylactosamine modified glycans, and/or glycoproteins. Methods for evaluating a test compound for its ability to regulate receptor clustering through glycans on cell surfaces; and methods for regulating receptor clustering on cell surfaces comprising altering glycans on the cell surface associated with receptor clustering are also discovered.

Compositions and methods for regulating receptor clustering

Compositions comprising modulators of cytokines of the TGF-.beta.

The invention relates to a method for assaying for the presence of a substance that modulates a cytokine of the TGF.beta. superfamily. A substance which is suspected of modulating a cytokine of the TGF.beta. superfamily and a TGF.beta. binding compound which is not a TGF.beta. receptor and which contains a TRH1 domain, or a portion or mimetic thereof, is reacted with a cytokine of the TGF.beta. superfamily under conditions where the compound, portion or mimetic thereof, and the cytokine are capable of forming a complex. Complexes, free compound and/or cytokine are assayed and compared with a control. The invention also relates to a composition comprising at least one compound which is not a TGF.beta. receptor and which contains the TRH1 domain or a portion, or a mimetic thereof, and a pharmaceutically acceptable carrier, auxiliary or excipient and to methods of treatment using the composition. Further the invention relates to a method of enhancing the activity of growth factors.
