摘要:
Methods are provided for treatment of cutaneous T cell lymphoma with an effective dose of an anti-CD47 agent, optionally combined an additional anti-cancer agent.
摘要:
Polypeptide compositions comprising a human immunoglobulin constant region with a modified IgG4 hinge region having an N-terminal deletion of 1, 2, 3, 4, 5 amino acids, relative to a native human IgG4 hinge sequence are provided. In some embodiments the hinge sequence further comprises the amino acid substitution S228P (Eu numbering). Polypeptides comprising the modified sequence optionally comprise a binding moiety specific for an epitope that is present on red blood cells; and can provide for reduced agglutination of hematopoietic cells compared to a comparable polypeptide with a native hinge region.
摘要:
High affinity PD-1 mimic polypeptides are provided, which (i) comprise at least one amino acid change relative to a wild-type PD-1 protein; and (ii) have an increased affinity for PD-L1 relative to the wild-type protein. Compositions and methods are provided for modulating the activity of immune cells in a mammal by administering a therapeutic dose of a pharmaceutical composition comprising a high affinity PD-1 mimic polypeptide, which blocks the physiological binding interaction between PD-1 and its ligand PD-L1 and/or PD-L2.
摘要:
Smooth muscle cells (SMC) from subjects carrying at least one 9p21 risk factor, can be resistant to efferocytosis, leading to the retention of such cells in the necrotic core of atherosclerotic plaque. In the methods of the invention, an agent that increases efferocytosis of cellular components of coronary plaque, including efferocytosis of apoptotic smooth muscle cells, is administered to the subject in a dose and for a period of time effective to stabilize, prevent or reduce atherosclerotic plaque in the individual.
摘要:
A set of markers for melanoma cancer stem cells are provided. The cells can be prospectively isolated or identified from primary tumor samples, and possess the unique properties of cancer stem cells in functional assays for tumor initiation, cancer stem cell self-renewal and differentiation. In addition, cancer stem cells can be used as a predictor for disease progression. The CSC have the phenotype of being positive for expression CD271.
摘要:
Acute myeloid leukemia stem cells (AMLSC) are identified. The cells can be prospectively isolated or identified from patient samples, and are shown to possess the unique properties of cancer stem cells in functional assays for cancer stem cell self-renewal and differentiation, and in cancer diagnosis.
摘要:
Populations enriched for myogenic progenitors are obtained by selection on the basis of expression of specific cell surface markers. The muscle progenitor cells are characterized as being CD45 - and CD34 + , and may further be characterized as lacking expression of Mac-1 (CD11b) and positive for expression of CXCR4 (CD184) and β1-integrin (CD29).
摘要:
Methods are provided for the prevention and treatment of vascular inflammation. The methods comprise administering to a human subject an effective dose of an agent that specifically binds to CD47, and reduces one or more indicia of vascular inflammation.
