abstract

background: fusion of dendritic cells (dcs) with melanoma cells could reinforce the antigenicity of tumors as a strategy for the treatment of malignant melanoma. however, the insufficient quantity of dcs and the low fusion efficiency limits the development of such approach. objective: to define the dosage of the stimulating factors as well as the induction condition for the optimal dcs preparation and cell fusion. methods: dcs were generated from murine bone marrow cells, and cultured with four different concentrations of the granulocyte-macrophage colony-stimulating factor (gm-csf) and interleukin-4 (il-4). dcs were confirmed to be mature by detecting the expression of mhc-ii, cd11c, cd80, and cd83 by flowcytometry. dcs-melanoma fusion cells were generated using polyethylene glycols (peg) with different molecular weights and the fusion efficiency was detected by fluorescence-activated cell sorter (facs). results: the largest quantity of dcs was found when cells were cultured with 1000 u/ ml of gm-csf and 500 u/ml of il-4 (1.69 ± 0.04 ×10 6 ml-1, p

Dendritic Cell Maturation with CpG for Tumor Immunotherapy

Background: Bacterial DNA has immunostimulatory effects on different types of immune cells such as dendritic cells (DCs). Application of DCs as a cellular adjuvant represents a promising approach in the immunotherapy of infectious disease and cancers. Objectives: To investigate the effect of tumor antigen pulsed DCs in the presence of CpG-1826 in treatment of a murine model of cancer. Methods: ...

Melanoma-infiltrating dendritic cells

The infiltration of melanoma lesions by dendritic cells (DCs) has been suggested to play a tumorigenic role due to the capacity of DCs to induce tumor tolerance and promote angiogenesis as well as metastasis. However, it has also been shown that tumor-infiltrating DCs (TIDCs) induce antitumor responses and hence may be targeted in cost-effective therapeutic approaches to obtain patient-specific...

Dendritic cells containing apoptotic melanoma cells prime human CD8+ T cells for efficient tumor cell lysis.

Dendritic cells (DCs) phagocytose apoptotic influenza-infected monocytes and cross-present influenza antigen to CD8+ T cells, generating a specific CTL response. We investigated whether apoptotic melanoma cells, presented by this mechanism, can lead to CTL responses to tumor-associated antigens and melanoma cells. Apoptotic HLA-A2- MEL-397 melanoma cells were internalized by HLA-A2+ immature mo...

Information Fusion for Anomaly Detection with the Dendritic Cell Algoritm

Dendritic cells are antigen presenting cells that provide a vital link between the innate and adaptive immune system, providing the initial detection of pathogenic invaders. Research into this family of cells has revealed that they perform information fusion which directs immune responses. We have derived a Dendritic Cell Algorithm based on the functionality of these cells, by modelling the bio...
