   Background & Aims: Dendritic cells (DCs) have high ability in antigen presentation. Their functional importance is in treatment of some diseases such as cancer and infection and autoimmune diseases, and prevention of allograft rejection. The aim of this study was to investigate maturation of Dendritic cells for tumor immunotherapy. Materials & Methods: DCs was produced in two stages. In the ...

Background and Objective: Using dendritic cells (DCs) loaded with tumor antigens as a therapeutic strategy against tumors has been proposed. In order to increase the efficacy of DCs, a variety of factors such as TLR ligand molecules and bacterial products are used. In this study, the protein components of the bacteria Listeria monocytogeneses (LM) for induction of dendritic cell maturation were...

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare hematodermic myeloid malignancy that is known to be derived from plasmacytoid dendritic cells which are characterized by expression of CD4, CD56, and more specific markers such as CD123. Here, the authors present three cases of BPDCN diagnosed in the past two years and address different available diagnostic modalities such as morpho...

human peripheral blood monocytes (hpbm) were cultured in the absence of human serum and were converted into a state exhibiting a high accessory function expressed by their ability of supporting lymphocyte proliferation. after a prolonged culture in serum free media the monocyte derived cells were highly viable, increased in size and developed veils and dendritiform elongatio'l1s. paralleli...

hla-g is normally expressed on human trophoblast cells. it is a non-classical mhc molecule class i b. the role of hla-g in diabetic type 1 is not known. we investigated the role of ifn-β in induction hla-g expression on the monocyte derived dendritic cells (dc) in diabetes type 1. treatment of dendritic cell with ifn-β in vitro from diabetic patients (n=20) and normal subjects (n=20) resulted t...

Objective: The hippocampal formation, particularly the dentate gyrus (DG), shows age-related morphological changes that could cause memory decline. It is indicated that Boswellia resins attenuates memory deficits and the major component of Boswellia serrata (Bs) gum resin, beta boswellic acid increased neurite outgrowth and branching in hippocampal neurons. This study was designed to investigat...

background: dendritic cells (dc) are a key regulator of the immune response, and interferon- beta (ifn-β) is considered an immunomodulatory molecule for dc. objective: the purpose of this study was to evaluate the ability of ifn-β treated dc to induce cytokine secretion by cd4+ t cells. methods: dendritic cells were generated from blood monocytes with granulocyte-monocyte colony-stimulating fac...

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 m...
