The present invention in certain embodiments provides a method of inhibiting PD-1 in a cell by administering a CD200 activation receptor ligand (CD200AR-L) to the cell. The present invention in certain embodiments provides a method of enhancing efficacy of a tumor lysate vaccine in a mammal comprising administering a CD200 activation receptor ligand (CD200AR-L) to the mammal prior to the administration of the tumor lysate vaccine.

CD200AR ligands for cancer immunotherapy

The present invention provides in certain embodiments compositions comprising at least one CD200 inhibitor, and methods of reversing or modulating immune suppression in a patient having a disease or disorder arising from abnormal cell growth, function or behavior, which method comprises administering to a patient in need thereof a CD200 inhibitor composition.

CD200 inhibitors and methods of use thereof

The present invention provides in certain embodiments conjugates comprising at least one CD200 inhibitor and an adjuvant, and methods of reversing or modulating immune suppression in a patient having a disease or disorder arising from abnormal cell growth, function or behavior, which method comprises administering to a patient in need thereof a composition comprising a CD200 inhibitor and an adjuvant.

This disclosure describes polypeptides fragments of annexin II, variants thereof, compositions that includes such fragments and/or variants, and methods of using such frag and/or variants.

Annexin II variant compositions and methods

The present invention provides compositions and methods that involve the 36 kDa annexin II monomer, which has been identified as having immunostimulatory properties. Accordingly, in one aspect, the invention provides compositions that include at least one 36 kDa annexin II monomer or an immunomodulatory fragment thereof. In another aspect, the invention provides methods that include administering to a subject a composition that includes at least one 36 kDa annexin II monomer or an immunomodulatory fragment thereof. In another aspect, the invention provides methods that induce an in situ increase in the 36 kDa annexin II monomer by administering to a subject an amount of composition effective to induce localized hypoxia sufficient to cause a localized increase in annexin II.

Annexin II compositions

The present invention is directed to compositions and methods for treating an animal diagnosed with Glioblastoma multiforme (GBM).
