Cell-extrinsic CTLA4-mediated regulation of dendritic cell maturation depends on STAT3

The Effects of Candida Albicans Cell Wall Protein Fraction on Dendritic Cell Maturation

Back ground: Candida albicans is a member of the normal human microflora. C. albicans cell wall is composed of several protein and carbohydrate components which have been shown to play a crucial role in C. albicans interaction with the host immune system. Major components of C. albican cell wall are carbohydrates such as mannans, β glucans and chitins, and proteins that partially modulate the h...

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: ...

Regulation of dendritic cell maturation and function by Bruton's tyrosine kinase via IL-10 and Stat3.

Btk plays crucial roles in the differentiation and activation of B and myeloid cells. Despite drastic reductions of other Ig isotypes, paradoxically high IgE responses have been known in btk mutant mice. Here we show that btk(-/-) dendritic cells exhibit a more mature phenotype and a stronger in vitro and in vivo T cell-stimulatory ability than wild-type cells. Increased IgE responses were indu...
