摘要: Soluble versions of heterodimeric receptors, e.g., CD94/NKG2 receptors, and methods of producing and using such constructs, are described. The constructs comprise soluble fragments of, each receptor monomer, and some constructs further comprise at least one immunoglobulin Fc domain. Exemplary constructs are those wherein (1) each soluble fragment is linked to an immunoglobulin Fc domain, which are then allowed to dimerize, (2) each soluble fragment is linked to an immunoglobulin Fc domain mutated to promote forced dimerization with the correct counterpart, and (3) single-chain constructs where the monomeric receptor fragments are linked, and the C-terminal fragment is linked to an Fc domain.

摘要: The present invention relates to agents that are non-competitive antagonists of the CD94/NKG2A receptor such as certain anti-NKG2A antibodies, in particular humanized versions of murine anti-NKG2A antibody Z199, as well as methods of producing and using such agents and antibodies.
