1. A polynucleotide that encodes a fusion protein comprising a first domain that activates an antigen-presenting cell (APC) and a second domain that activates an immune effector cell, wherein
(i) the first domain comprises an antibody that binds an activation receptor of the APC, or an antigen-binding fragment thereof; and
(ii) the second domain comprises a co-stimulatory receptor of the immune effector cell, or a functional fragment thereof;
wherein the first domain is an anti-CD40 scFv having an amino acid sequence selected from the group consisting of SEQ ID NOs:75, 78, 81, 87, and 90.
