Graphical Abstract Patient-specific iPS cells with JAK2 V617F mutation differentiate into DC3 dendritic cells, megakaryocytes and red blood cells.

cd40 is recognized as a member of tumor necrosis factor receptor super family. it is expressed by the immune and non-immune cells. its interaction with cd40 ligand (cd154) brings about  a regulatory effect on  the cellular and humoral immunity. the pathway of cd40-cd154 is influential in various diseases. investigations on such diseases have revealed dimensional mechanisms whereby this route in...

Background: Generation of monocyte-derived dendritic cells (MDDC) is induced in the presence of GM-CSF and IL-4, and a maturation stimulus is added to the monocyte culture to obtain mature Dendritic Cells (DCs) suitable for therapy. TNF-α is the most common cytokine used for activating DCs and generating mature MDDC either alone or in combination with other cytokines. Objective: To compare effe...

background: the langerhans cells (lcs) are dendritic cells (dcs) which belong to the group of antigen presenting cells (apcs). their function is to recognize the antigen, capture it, and present it to the t lymphocytes; thus initiating an early immune response. the antigen presenting functional lcs may play an important part in initiation and development of gingivitis. the aim of this study was...

objective: it is believed that monocyte isolation methods and maturation factors affect the phenotypic and functional characteristics of resultant dendritic cells (dc). in the present study, we compared two monocyte isolation methods, including plastic adherence-dendritic cells (adh-dc) and magnetic activated cell sorting- dendritic cells (macs-dc), and their effects on phagocytic activity of d...

during antigen capture and processing, mature dendritic cells (dc) express large amounts of peptide-mhc complexes and accessory molecules on their surface. we investigated the role of ifn-β in induction hla-g expression on the monocyte derived dc and cytokine profile in diabetes type 1. we accomplished secretary pattern and total cytokine production of the th1 cytokine (il-2, γifn) and th2 cyto...

Objective(s):Growing evidence indicates that extract of Ginkgo biloba (EGb) attenuates hippocampal-dependent memory deficit in aged individuals; however, very little is known about the effect of EGb on the structure of hippocampus. Therefore we examined the EGb-induced morphological changes of the Cornu Ammonis (CA) region in aged rats. Materials and Methods: Sixteen aged male Wistar rats, 24 ...

Introduction Dendritic cells (DCs) are bone marrow-derived cells, which migrate to lymphoid and non-lymphoid organs via blood. Liver DCs are believed to play an important role in the regulation of hepatic allograft acceptance. However, because of inherent difficulties in isolating adequate numbers of DCs from liver, limited information is available on the phenotype and functions of liver DCs. ...

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...
