Abstract: The present invention is based, in part, on the discovery of anti-PSGL-1 compositions (e.g., monoclonal antibodies and antigen-binding fragments thereof) that regulate myeloid cell inflammatory phenotypes, such as suppressive myeloid cells, monocytes, macrophages, neutrophils, and/or dendritic cells, including polarization, activation, and/or function, and methods of using such anti-PSGL-1 compositions for therapeutic, diagnostic, prognostic, and screening purposes.

Abstract: The present invention is based, in part, on the discovery of anti-SIGLEC-9 composition (e.g., monoclonal antibodies and antigen-binding fragments thereof), that regulate myeloid cell inflammatory phenotypes, such as suppressive myeloid cells, monocytes, macrophages, neutrophils, and/or dendritic cells, including polarization, activation, and/or function, and methods of using such anti-SIGLEC-9 compositions for therapeutic, diagnostic, prognostic, and screening purposes.

Abstract: The present invention is based, in part, on the discovery of anti-LRRC25 compositions (e.g., monoclonal antibodies and antigen-binding fragments thereof), that regulate inflammatory phenotypes of myeloid cells, such as suppressive myeloid cells, monocytes, macrophages, neutrophils, and/or dendritic cells, including polarization, activation, and/or function, and methods of using such anti-LRRC25 compositions for therapeutic, diagnostic, prognostic, and screening purposes.

Abstract: The present invention is based, in part, on the discovery of anti-CD53 compositions (e.g., monoclonal antibodies and antigen-binding fragments thereof), that regulate inflammatory phenotypes of myeloid cells, such as suppressive myeloid cells, monocytes, macrophages, neutrophils, and/or dendritic cells, including polarization, activation, and/or function, and methods of using such anti-CD53 compositions for therapeutic, diagnostic, prognostic, and screening purposes.

Abstract: The present invention provides a method of mediating hypo-activation of NK cells. Methods of the present invention comprise administering to a subject an effective amount of broad acting phosphotase inhibitor, such as sodium orthovanadate, SHP specific inhibitor. In one embodiment, the SHP specific inhibitor is NSC119910.

Abstract: The instant invention teaches the inhibition of SHIP expression, or function for the increased efficacy of autologous stem cell transplants. In another embodiment, interference with SHIP function can be used to temporarily expand and mobilize the hematopoietic stem cell compartment to assist with leukapheresis, to promote hematopoietic recovery after myeloablation treatments, to deplete target stem cell clones (such as leukemic clones and other tumor stem cell types), and to deplete, or damage, the repopulating ability of the endogenous hematopoietic stem cell pool in order to allow transplanted hematopoietic stem cells to better home and engraft and to promote in vivo expansion and mobilization of other organ-specific stem cell populations (e.g., mesenchymal, mammary).
