RATIONALE: Studying samples of blood and bone marrow from patients with cancer in the laboratory may help doctors learn more about T cells and plan better treatment for multiple myeloma.
PURPOSE: This research study is looking at T cells in blood and bone marrow samples from patients with multiple myeloma.
|Condition or disease||Intervention/treatment|
|Multiple Myeloma and Plasma Cell Neoplasm||Other: flow cytometry Other: immunoenzyme technique Other: laboratory biomarker analysis|
- To evaluate the feasibility of expanding myeloma-specific T cells using autologous ex vivo expanded B cells loaded with myeloma antigens as antigen-presenting cells (B-APCs) in peripheral blood and bone marrow samples from patients with multiple myeloma.
- To examine the feasibility of selecting and expanding myeloma-specific T cells ex vivo using interferon γ release and CD3/CD28 stimulation.
OUTLINE: Peripheral blood and bone marrow samples are collected periodically for laboratory studies. Samples are analyzed to assess the feasibility of expanding autologous B cells ex vivo using CD40L and IL-4; the antigen-presenting phenotype of autologous B-cell antigen-presenting cells (B-APCs) using flow cytometry; and the antigen-presenting function of B-APCs using ELISPOT and chromium-release assay. Myeloma-specific interferon γ secreting T cells are isolated and selected using Miltenyi beads. The selected myeloma-specific T cells are expanded ex vivo using anti CD3/CD28 beads.
