Abstract
The invention relates to the field of molecular medicine. In particular, it relates to compositions and methods to enhance the clearance of aberrant cells, e.g. cancer cells or virus-infected cells, by the host's immune system. Provided is a composition comprising (i) a therapeutic compound that can trigger a host's immune effector cells against an aberrant cell, such as a therapeutic antibody, and (ii) at least one agent capable of reducing or preventing inhibitory signal transduction initiated via SIRPalpha.
Claims2
A method for treating a viral infection in a host comprising administering an agent capable or reducing or inhibiting the interaction between SIRPα and CD47 in the host, wherein the viral infected host would benefit from enhanced phagocytosis by myeloid and/or phagocytic cells and wherein the viral infected host would benefit from enhanced antibody-dependent cellular cytotoxicity (ADCC).
