    摘要: Isolated nucleic acid molecules encoding novel CD100 molecules which stimulate a leukocyte response, such as a B cell response, including B cell aggregation, B cell differentiation, B cell survival, and/or T cell proliferation are disclosed. These novel molecules have a certain homology to semaphorins, proteins which are growth cone guidance molecules that are critical for guiding growing axons of neurons to their targets. In addition to isolated nucleic acids molecules, antisense nucleic acid molecules, recombinant expression vectors containing a nucleic acid molecule of the invention, host cells into which the expression vectors have been introduced are also described. The invention further provides isolated CD100 proteins, fusion proteins and active fragments thereof. Diagnostic and therapeutic methods utilizing compositions of the invention are also provided.

    摘要: We teach a strategy to obtain large quantities of desired APCs, activated B cells, which are superior in their capacity to present tumor protein antigen in a multiadministration protocol. Human B cells can be obtained from peripheral blood in large numbers. These cells can be activated in vitro by coculture with CD40L (CD40-B cells) and an immunosuppressive agent such as cyclosporin A. They can expanded up to 1×103 to 1×104 fold in 2 weeks or 1×105 to 1×106 fold in 2 months. We demonstrate these cells are most efficient APCs comparable to DCs in stimulating allogeneic CD4+ CD45RA+, CD4+ CD45RO+, and CD8+ T cells. In contrast to DCs, CD40-B cells are fully functional even in the presence of immunosuppressive cytokines such as IL-10 and TGFβ.

    摘要: Structural forms of T cell costimulatory polypeptides are described. These forms comprise an alternative structural domain (i.e., a structural domain having an amino acid sequence which differs from a known amino acid sequence) or have a structural domain deleted or added. The structural forms correspond to naturally-occurring alternatively spliced forms of T cell costimulatory polypeptides or variants thereof which can be produced by standard recombinant DNA techniques. In one embodiment, the T cell costimulatory polypeptide of the invention contains an alternative cytoplasmic domain. In another embodiment, the T cell costimulatory polypeptide of the invention contains an alternative signal peptide domain or has an immunoglobulin variable region-like domain deleted. The alternative structural forms of T cell costimulatory polypeptides can be used to identify agents which stimulate the expression of alternative forms of costimulatory polypeptides and to identify components of the signal transduction pathway which results in costimulation of T cells.
