Stimulation of dendritic cell functional maturation by capsid protein from chikungunya virus

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...

Expression of the capsid protein of Chikungunya virus in a baculovirus for serodiagnosis of Chikungunya disease.

Chikungunya virus (CHIKV) causes endemic or epidemic outbreaks of CHIK fever, which typically manifests as a febrile illness. To develop a CHIKV-specific diagnostic test, CHIKV capsid protein was expressed using a baculovirus expression system. The seroreactvity of the recombinant CHIKV capsid protein was evaluated by ELISA and immuochromatographic assay (ICA), using 40 anti-CHIKV-positive and ...

The VP35 protein of Ebola virus impairs dendritic cell maturation induced by virus and lipopolysaccharide.

Ebola virus causes rapidly progressive haemorrhagic fever, which is associated with severe immuosuppression. In infected dendritic cells (DCs), Ebola virus replicates efficiently and inhibits DC maturation without inducing cytokine expression, leading to impaired T-cell proliferation. However, the underlying mechanism remains unclear. In this study, we report that Ebola virus VP35 impairs the 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...

Improved Function and Maturation of Dendritic Cells Stimulated by Recombinant pp65 Protein: In vitro Design

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: ...
