  • Patent number: 11155621
    Abstract: The present invention provides antibodies that bind to CD3 and methods of using the same. According to certain embodiments, the antibodies of the invention bind human CD3 with high affinity and induce human T cell proliferation. The invention includes antibodies that bind CD3 and induce T cell-mediated killing of tumor cells. According to certain embodiments, the present invention provides bispecific antigen-binding molecules comprising a first antigen-binding domain that specifically binds human CD3, and a second antigen-binding molecule that specifically binds human CD20. In certain embodiments, the bispecific antigen-binding molecules of the present invention are capable of inhibiting the growth of B-cell tumors expressing CD20. The antibodies and bispecific antigen-binding molecules of the invention are useful for the treatment of diseases and disorders in which an upregulated or induced targeted immune response is desired and/or therapeutically beneficial.

  • Patent number: 11124767
    Abstract: Many cell types in the body can remove apoptotic and cellular debris from tissues; however, the professional phagocyte, or antigen presenting cell (“APC”), has a high capacity to do so. The recognition of apoptotic cells (“ACs”) occurs via a series of evolutionarily-conserved, AC associated molecular-pattern receptors (“ACAMPRs”) on APCs that recognize and bind corresponding apoptotic-cell-associated molecular patterns (“ACAMPs”). These receptors recognize ligands such as phosphotidyl serine and oxidized lipids found on apoptotic cells. Savill et al. (2002); and Gregory et al. (2004).
