The liver contains a variety of resident immune cells, such as NK cells, NKT cells, T cells, macrophages, and dendritic cells. However, little is known about how IL-7, which is produced by hepatocytes, functions locally in development and maintenance of liver immune cells. To address this question, we established IL-7-floxed mice and crossed them with albumin promoter-driven Cre (Alb-Cre) trans...
Objective(s): Dendritic cells (DCs) play a critical role in activation of T cell responses. Induction of type1 T helper (Th1) immune response is essential to generate protective immunity against cutaneous leishmaniasis. The intrinsic tendency of liposomes to have interaction with antigen-presenting cells is the main rationale to utilize liposomes as antigen carriers. In the present study, the e...
Interdigitating dendritic cell sarcoma is an extremely rare malignancy derived from antigen-presenting cells. Dendritic cells constitute a heterogeneous group of cells, which includes Langerhans cells, dermal dendrocytes, follicular dendritic cells, and interdigitating dendritic cells present in lymphoid and nonlymphoid organs. We report the case of a 36-year-old woman who presented with epigas...
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 ...
purpose: to investigate confocal scan features of corneal subbasal nerve plexus and epithelial dendritic cells in herpes simplex keratitis (hsk) as compared to acanthamoeba keratitis (ak). methods: confocal scan records of patients with clinical and confocal microscopic features compatible with hsk and ak as well as confocal scan records of normal participants were reviewed. the density and mor...
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...
