Ex-vivo priming for generating cytotoxic T lymphocytes specific for non-tumor antigens to treat autoimmune and allergic disease |
摘要 |
<p>Cytotoxic T lymphocytes (CTLs) specific for antigenic peptides derived from IgE molecules can be generated <Italic>in vitro</Italic> 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 <Italic>in vitro</Italic> and inhibit antigen specific IgE responses <Italic>in vivo</Italic>. In addition, adoptive transfer of the IgE specific CTLs to an asthmatic mouse model can inhibit the development of lung inflammation and airway hypersensitivity. IgE specific CTLs provide a treatment for allergic asthma and other IgE-mediated allergic diseases. Antigenic peptides identified from non-tumor self-antigens induce specific cytotoxic T lymphocytes (CTLs) <Italic>in vitro.</Italic> The CTLs induced by peptides identified from CD40L can kill activated CD4+ T cells. <Italic>In vitro</Italic> generated CTLs specific for CD40L inhibit CD4-dependent antibody responses of all isotypes <Italic>in vivo.</Italic> In contrast, CTLs 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. <Italic>In vitro</Italic> generated CTLs specific for non-tumor self-antigens expressed on activated CD4+ T cells regulate immune responses <Italic>in vivo</Italic>.</p> |
