Abstract
The present invention provides compositions and methods for modulating one or more phenotypes of a macrophage-related cell, e.g., a macrophage. The invention further provides methods of treating disease by modulating macrophage phenotype. Representative phenotypes include pro-inflammatory, anti-inflammatory, immunogenic, tolerogenic, tissue-destructive, tissue restorative, cytotoxic, migratory, bone-resorbing, pro-angiogenic, anti-angiogenic, suppressor, antigen presentation, or phagocytic. Representative diseases include atherosclerosis, arthritis, and multiple sclerosis.
Claims20
A method of modifying a phenotypic characteristic or phenotype of a macrophage-related cell in the body of a subject or comprising administering an effector to the subject, wherein the effector is administered in an amount sufficient to cause a change in at least one phenotypic characteristic or phenotype of the macrophage-related cell, and wherein the macrophage-related cell is selected from the group consisting of:
- dendritic cells, monocytes, osteoclasts, and macrophages, and wherein administration of the effector optionally results in a change in the expression level of at least one gene in the macrophage-related cell.
