|
This CTL line was derived from peripheral blood mononuclear cells of a patient with metastatic carcinoma who had been treated with a recombinant CEA-vaccinia vaccine in a Phase I trial; the CTLs were analyzed through 20 in vitro cycle passages of stimulation with CAP-1 peptide and interleukin 2 in the presence of autologous antigen-presenting cells.
|

|
The CTL line was shown to be phenotypically stable in terms of high levels of cytokine (IFN-gamma, tumor necrosis factor, and granulocyte-macrophage colony-stimulating factor) production, expression of homing-adhesion molecules, ability to lyse peptide-pulsed targets, and ability to lyse human carcinoma cells endogenously expressing CEA in a MHC-restricted manner.

Heat shock proteins (HSP) have been revealed to interact with antigen-presenting cells and have potent adjuvant capability to induce antigen-specific CD8+ CTL and Th1 responses.
|
31 |

|
Our previous work shows how Hsp70-like protein 1 (Hsp70L1), as a new member of the Hsp70 subfamily, acts as potent Th1 adjuvant.

|
Here, we report the efficient induction of tumor antigen-specific immune response by dendritic cells pulsed with recombinant fusion protein of Hsp70L1 and CEA(576-669) fragment of the carcinoembryonic antigen (CEA) containing CAP-1 (a HLA-A2-restricted CTL epitope).
|
33 |
15930317
|
Fusion protein CEA(576-669)-Hsp70L1 can promote dendritic cell maturation and activate dendritic cells to produce cytokines, such as interleukin-12, interleukin-1beta, and tumor necrosis factor-alpha, and chemokines, such as macrophage inflammatory protein-1alpha, macrophage inflammatory protein-1beta, and regulated on activation, normal T expressed and secreted, indicating the adjuvant ability of Hsp70L1 in the fusion protein.
|

|
CEA-specific HLA-A2.1-restricted CD8+ CTLs either from patients with CEA+/HLA-A2.1+ colon carcinoma or from splenocytes of immunized HLA-A2.1/Kb transgenic mice can be generated more efficiently after stimulations or immunizations with dendritic cells pulsed by CEA(576-669)-Hsp70L1 than with dendritic cells pulsed by CEA(576-669) alone, resulting in secreting more Th1 cytokine IFN-gamma and killing target cells more potently in an antigen-specific and HLA-A2.1-restricted manner.
|
35 |
15930317
|
Adoptive transfer of splenocytes from transgenic mice immunized with CEA(576-669)-Hsp70L1-pulsed dendritic cells can inhibit tumor growth and prolong survival in nude mice bearing CEA+/HLA-A2.1+ human colon carcinoma more markedly.

Induction of potent and sustained antitumor immunity depends on the efficient activation of CD8(+) and CD4(+) T cells.

|
Our previous studies suggested that vaccination with an anti-idiotype antibody 3H1, which mimics a specific epitope of carcinoembryonic antigen (CEA), has the potential to break immune tolerance to CEA and induce anti-CEA antibody as well as CEA-specific CD4(+) T-helper responses in colon cancer patients as well as in mice transgenic for human CEA.
|
42 |
17363612
|
The overall immune responses and survival were enhanced in groups of mice immunized with agonist peptide for CEA(691) (YMIGMLVGV)-pulsed dendritic cells or CAP1-6D (YLSGADLNL, agonist peptide for CAP-1)-pulsed dendritic cells.

45 |
17564703
|
In the present study, we show that CAP1-6D, a superagonist analogue of a carcinoembriyonic antigen (CEA)-derived HLA-A*0201-restricted epitope widely used in clinical setting, reproducibly promotes the generation of low-affinity CD8(+) T cells lacking the ability to recognized CEA-expressing colorectal carcinoma (CRC) cells.
|
46 |
17564703
|
Short-term T cell cultures, obtained by priming peripheral blood mononuclear cells from HLA-A*0201(+) healthy donors or CRC patients with CAP1-6D, were indeed found to heterogeneously cross-react with saturating concentrations of the native peptide CAP1, but to fail constantly lysing or recognizing through IFN- gamma release CEA(+)CRC cells.
|
47 |
17564703
|
Characterization of anti-CAP1-6D T cell avidity, gained through peptide titration, CD8-dependency assay, and staining with mutated tetramers (D227K/T228A), revealed that anti-CAP1-6D T cells exerted a differential interaction with the two CEA epitopes, i.e., displaying high affinity/CD8-independency toward the APL and low affinity/CD8-dependency toward the native CAP1 peptide.
