The present disclosure provides methods of treating a subject having a proliferative disease or an autoimmune disorder with a combination of (a) a first multispecific binding molecule (MBM) that binds specifically to (i) human CD2 and (ii) a human tumor-associated antigen and/or a human tumor microenvironment antigen, and (b) a second multispecific binding molecule that binds specifically to (i) a component of a human T-cell receptor (TCR) complex or a secondary T-cell signaling molecule and (ii) a human tumor-associated antigen and/or human tumor microenvironment antigen. The disclosure further provides MBMs and combinations of MBMs that can be used in the methods of the disclosure.

Provided are compositions for increasing the half-life of a polypeptide or polypeptides in a canine and methods of their use. The compositions involve variant canine IgG Fc regions.

The invention disclosed herein relates to improved methods for expanding cell populations, particularly B cell populations. The invention further relates to improved B-cell expansion media, compositions comprising expanded B cells and methods of using such expanded B cells. The invention further relates to methods of treating diseases or disorders wherein a population of B cells is obtained and cultured, and wherein said B cells are engineered to express a payload and/or a chimeric receptor, and wherein said B cells are administered to a subject.

Provided herein are recombinant poxviruses that are stable through successive passaging of the recombinant poxviruses. More particularly, the recombinant poxviruses comprise one or more modified nucleic acids encoding MUC1, CEA, and/or TRICOM antigens, wherein the recombinant poxviruses are stable through successive passaging. Also, provided herein are compositions and method related thereto.

The present disclosure provides CD2 binding molecules that specifically bind to CD2, including monospecific, bispecific and trispecific binding molecules, conjugates comprising the CD2 binding molecules, and pharmaceutical compositions comprising the CD2 binding molecules and the conjugates. The disclosure further provides methods of using the CD2 binding molecules to modulate CD2 signaling in order to treat a variety of immune (e.g., autoimmune), inflammatory and proliferative disorders. The disclosure yet further provides recombinant host cells engineered to express the CD2 binding molecules and methods of producing the CD2 binding molecules by culturing the host cells under conditions in which the CD2 binding molecules are expressed.

Provided herein are cell-distancing devices that protect cells that comprise them against host immune response when administered in a host. The disclosed cell-distancing devices engage with host immune cells and reduce their activity against cells that comprise the devices. Compositions of cell-distancing devices, cells comprising cell-distancing devices, and method of making and using such compositions are disclosed herein.

Provided is an engineered immune cell. The expressions of at least one MHC related gene and at least one NK activating receptor binding molecule are suppressed or silenced, so as to suppress the killing of the engineered immune cell by NK cells. Also provided are a pharmaceutical composition comprising the engineered immune cell and use of the engineered immune cell in preparation of drugs for treatment of cancer, infection, or autoimmune diseases.

Provided are compositions for increasing the half-life of a polypeptide or polypeptides in a canine and methods of their use. The compositions involve variant canine IgG Fc regions.

Provided herein are recombinant poxviruses that are stable through successive passaging of the recombinant poxviruses. More particularly, the recombinant poxviruses comprise one or more modified nucleic acids encoding MUC1, CEA, and/or TRICOM antigens, wherein the recombinant poxviruses are stable through successive passaging. Also, provided herein are compositions and method related thereto.
