    摘要: A method of carrying out adoptive immunotherapy by administering a subject an antigen-specific cytotoxic T lymphocytes (CTL) preparation in a treatment-effective amount is described. In the method, the CTL preparation is preferably administered as a preparation of an in vitro antigen-stimulated and expanded primate CTL population, the CTL population: (i) depleted of FoxP3+ T lymphocytes prior to antigen stimulation; (ii) antigen-stimulated in vitro in the presence of interleukin-21; or (iii) both depleted of FoxP3+ T lymphocytes prior to antigen stimulation and then antigen-stimulated in vitro in the presence of interleukin-21. Methods of preparing such compositions, and compositions useful for carrying out the adoptive immunotherapy, are also described.

    摘要: What is described is a novel genetic screen, involving recombinant technology and class I antigen cross-presentation, to search for supraoptimal superagonists of the 27L MART-1 mutant selecting for single amino acid substitution mutants of 27L that activate human antigen-specific CTL clones recognizing the wild-type MART-126-35 epitope. Three novel mutant epitopes are identified with superagonist properties that are functionally superior to 27L. The ability of a given analog to act as superagonist varies among patients. Also described is the use of methods to establish panels of potential superagonist APLs to individualize tumor peptide vaccines among patients. The methodology is replicated to identify APL to NY-ESO-1157-165 and NY-ESO-1157-170 tumor epitopes. A general method is described that is useful to produce a tumor vaccine to any tumor epitope.

    摘要: Methods for preparing ex vivo T cell cultures using IL-21 compositions for use in adoptive immunotherapy are described. Addition of IL-21 to cultures of non-terminally differentiated T cells population, either isolated or present in peripheral blood mononuclear cells are exposed to one or more tumor antigens, and in the presence of IL-21 compositions and antigen presenting cells (APCs), the resulting T cell population has an enhanced antigen-specificity, and can be reintroduced into the patient. Methods are also disclosed for identifying tumor antigens by culturing T cell populations exposed to IL-21 compositions and APCs in the presence of tumor material.
