Abstract

The present invention relates to chimeric immune receptor molecules for reducing or eliminating tumors. The chimeric receptors are composed a C-type lectin-like natural killer cell receptor, or a protein associated therewith, fused to an immune signaling receptor containing an immunoreceptor tyrosine-based activation motif. Methods for using the chimeric receptors are further provided.

Claims

1. A nucleic acid construct for expressing a chimeric receptor comprising:

a first nucleic acid sequence encoding a promoter operably linked to a second nucleic acid sequence encoding a chimeric receptor comprising a C-type lectin-like natural killer cell receptor, fused to a nucleic acid encoding an immune signaling receptor containing an immunoreceptor tyrosine-based activation motif of SEQ ID NO;

1.

2. The nucleic acid construct of claim 1, wherein the construct is in a vector.

3. The nucleic acid construct of claim 1 further comprising a suicide gene.

4. An isolated T cell comprising the nucleic acid construct of claim 1 or 3, or the vector of claim 2.
