英文摘要

Dendritic cells (DCs), which are potent antigen presenting cells (APCs), are utilized to deliver the signals essential for the initiation of immune responses. In this study, we used an interdisciplinary approach to characterize the effect of K562 cells, a human chronic myeloid leukemia (CML) cell line, on the biomechanical characteristics and immune functions of DCs. When co-cultured with K562 cells, the biomechanical and immunological characteristics of immature DCs (imDCs) and mature DCs (mDCs) were severely impaired compared with controls. The changes include increased membrane viscoelasticity, reorganized cytoskeleton (F-actin), suppressed capability of antigen uptake, transen-dothelium migration, and activation of naive T cells. In exploring the mechanisms of these changes, we identified several genes and proteins by microarray analysis and 2D gel electrophoresis. Changes were found in the cytoskeleton-related genes and proteins (such as cofilin1 and profilin1) and matrix-related genes and proteins (such as TIMP1 and MMP9). These findings provide a molecular basis for the biomechanical and immunological changes of DCs in response to K562 and may help to elucidate the mechanism for tumor immune escape.
