Mycobacterium lepraeInhibits Dendritic Cell Activation and Maturation

Mycobacterium leprae inhibits dendritic cell activation and maturation.

Leprosy presents with a clinical spectrum of skin lesions that span from strong Th1-mediated cellular immunity and control of bacillary growth at one pole to poor Ag-specific T cell immunity with extensive bacillary load and Th2 cytokine-expressing lesions at the other. To understand how the immune response to Mycobacterium leprae is regulated, human dendritic cells (DC), potent inducers of ada...

Activation and Maturation Inhibits Dendritic Cell Mycobacterium leprae

Immunomodulatory Effects of Mice Mesenchymal Stem Cells on Maturation and Activation of Dendritic Cells

Background: Mesenchymal stem cells (MSCs) possess a wide range of immunomodulatory functions mostly in immune cells including dendritic cells (DCs). DCs are the key cells in the immune response and play an important role in initiating cell-mediated immunity. Objective: To evaluate the immunomodulatory effects of MSCs supernatant on maturation and function of DCs. Methods: Bone marrow derived m...

Comparison of Several Maturation Inducing Factors in Dendritic Cell Differentiation

Background: Dendritic cells (DCs) are professional antigen presenting cells that have an important role in the initiation of immune response. The use of maturation factors in dendritic cell differentiation provides a promising approach in immunotherapy. Objective: In this study, we compared tumor necrosis factor-α, polyribocytidylic acid, lipopolysacharide and CpG oligonucleotides in inducing d...

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: ...
