Abstract
Compositions, methods, and uses of recombinant B7-H4 protein or binding motifs to B7-H4 protein that can reduce the immune suppression effect of B7-H4 in relation to T cell activation, proliferation, and conversion. Preferably, the recombinant B7-H4 protein has a plurality of mutations in N-glycosylation residue to reduce its inhibitory effect to T cell activation and proliferation. The recombinant protein having binding motifs to B7-H4 protein preferably includes a binding motif to IgC domain and another binding motif to IgV domain such that the immune-suppressive effects by two Ig-like domains are concurrently reduced.
