Abstract: The invention features multi-specific protein complexes with one domain comprising IL-15 or a functional variant and a binding domain specific to a disease antigen, immune checkpoint or signaling molecule.

Abstract: Provided herein are methods of killing or reducing the number of naturally-occurring and/or treatment-induced senescent cells and diseased cells in a subject in need thereof, decreasing the accumulation of naturally-occurring and/or treatment-induced senescent cells and diseased cells in a subject in need thereof, that include administering to the subject a therapeutically effective amount of one or more common gamma-chain family cytokine receptor activating agent(s) and/or one or more agent(s) that result(s) in a decrease in the activation of a TGF-? receptor.

Abstract: The invention features multi-specific fusion protein complexes with one domain comprising IL-15 or a functional variant and a binding domain specific to IL-12 or IL-18.

Abstract: The present invention features compositions and methods featuring ALT-803, a complex of an interleukin-15 (IL-15) superagonist mutant and a dimeric IL-15 receptor ?/Fc fusion protein useful for enhancing an immune response against a neoplasia (e.g., multiple myeloma, melanoma, lymphoma) or a viral infection (e.g., human immunodeficiency virus).

Abstract: The invention features soluble fusion protein complexes comprising at least two soluble fusion proteins. For example, the first fusion protein is an anti-CD3 antibody covalently linked to an interleukin-15 (IL-15) polypeptide or functional fragment thereof. The second fusion protein comprises a binding domain that recognizes disease antigens, wherein this domain is covalently linked to a soluble interleukin-15 receptor alpha (IL-15R?) polypeptide or a functional fragment thereof. One or both of the first and second fusion proteins further includes an immunoglobulin Fc domain or a functional fragment thereof, and the IL-15 domain of first fusion protein binds to the soluble IL-15R? domain of the second fusion protein to form a soluble fusion protein complex. The invention further provides methods for making and using the complexes of the invention.

Abstract: The instant invention provides TCRs having one or more amino acid substitutions that bind to the AL9 epitope of the HIV protein vpr (AIIRILQQQL).
