摘要： Cytotoxic T lymphocytes (CTLs) specific for antigenic peptides derived from IgE molecule can be generated in vitro by stimulating resting naive CD8 T cells with IgE peptides presented by artificial antigen presenting cells. The IgE specific CTLs lyse the target cells loaded with IgE peptides in vitro and inhibit antigen specific IgE response in vivo. In addition, adoptive transfer of the IgE specific CTL to an asthmatic mouse model can inhibit the development of lung inflammation and airway hypersensitivity. IgE specific CTL provides a treatment for allergic asthma and other IgE-mediated allergic diseases. Antigenic peptides identified from non-tumor self-antigens induce specific cytotoxic T lymphocyte (CTL) in vitro. The CTL induced by peptides identified from CD40L can kill activated CD4 T cells. In vitro generated CTL specific for CD40L inhibit CD4-dependent antibody responses of all isotypes in vivo. In contrast, CTL induced by antigenic peptides derived from IgE specifically inhibit IgE responses, and adoptive transfer of CD40L-specific CTL to NOD mice at early age delay the development of diabetes in NOD mice. In vitro generated CTL specific for non-tumor self-antigens expressed on activated CD4 T cells regulate immune responses in vivo.

摘要： T cell responses are often diminished in humans with a compromised immune system. We have developed a method to isolate, stimulate and expand naïve cytotoxic T lymphocyte precursors (CTLp) to antigen-specific effectors, capable of lysing tumor cells in vivo. This ex vivo protocol produces fully functional effectors. Artificial antigen presenting cells (AAPCs; Drosophila melanogaster) transfected with human HLA class I and defined accessory molecules, are used to stimulate CD8+ T cells from both normal donors and cancer patients. The class I molecules expressed to a high density on the surface of the Drosophila cells are empty, allowing for efficient loading of multiple peptides that results in the generation of polyclonal responses recognizing tumor cells endogenously expressing the specific peptides. The responses generated are robust, antigen-specific and reproducible if the peptide epitope is a defined immunogen. This artificial antigen expression system can be adapted to treat most cancers in a significant majority of the population.

摘要： A new method to capture, purify and expand antigen-specific T lymphocytes has been developed using magnetic beads coated with recombinant MHC class I molecules. This method was optimized using homogenous populations of naive T cells purified from mice transgenic for the 2C T cell receptor (TCR). These T cells were captured on beads coated with MHC class I molecules and the relevant antigenic peptides. MHC and peptide specificity was confirmed by the usage of irrelevant MHC peptide combinations. An enrichment of 800 to 1600 fold was measured, using 2C T cells mixed with irrelevant T cells, starting from a 2C T cell frequency of 1/3000. The same approach was used to purify antigen-specific CD8+ T cells from total CD8+ T cells from naive mice. The recovered cells could be expanded and specifically kill target cells in vitro; they had a significant effect in vivo as well. We expect this procedure to be suitable to purify and expand in vitro tumor- and virus-specific killer T cells for use in cell therapy.
