  • Patent number: 7063845
    Abstract: The invention is directed to human antibodies that bind CD40 (e.g., human CD40), methods of producing the antibodies and methods of use. Invention human CD40 antibodies include antibodies that can modulate one or more activities of CD40, such as increasing or decreasing cell proliferation. Invention human CD40 antibodies are therefore useful for increasing or decreasing a CD40 activity in order to alter CD40 activity in vivo.

  • Patent number: 7056677
    Abstract: This invention provides pharmaceutical compositions and methods for controlling and modifying Natural Killer (NK) cell and T cell functions by manipulation of “mast cell function-associated antigen,” or “MAFA,” polypeptide-mediated cell signaling. The invention provides a pharmaceutical compositions and methods using an agent that specifically binds to an MAFA ligand on a target cell and prevents or inhibits NK- or T cell-expressed cell surface MAFA from binding to the MAFA ligand on the target cell. Preventing or inhibiting an NK- or a T cell-expressed cell surface MAFA from binding to the MAFA ligand on the target cell prevents or inhibits the cell surface MAFA from generating an inhibitory signal to the NK or the T cell.

  • Publication number: 20030153073
    Abstract: Methods for expanding T cells (e.g., V&agr;24+V&bgr;11+ human NKT cells ) in vitro by repeated culturing in the presence of an antigen (e.g., glycosphingolipid), antigen presenting cells, and a cell survival factor are provided. A population of NKT cells (V&agr;24+&zgr;&bgr;11+) can be expanded more than 1 million-fold in 5 weeks and more than 1 billion-fold in 10 weeks.
