Dendrite cells

AQP7 is expressed in the proximal tubule of the kidney, testis, gastrointestinal tract, immature dendritic cells and ear. This glycerol channel is also highly expressed in adipocytes where it is thought to control the release of triglycerides. [Pg.216]

Dendritic cells (DC) are important antigen-presenting cells mostly derived from the bone marrow. Microscopically they show characteristic long cytoplasmic extensions called dendrites. There are several types of specialized DC present in all lymphoid tissues and major... [Pg.420]

SCF (recombinant product ancestim) is an early-acting hematopoietic growth factor that stimulates the proliferation of primitive hematopoietic and nonhema-topoietic cells [7]. In vitro, SCF has minimal effect on hematopoietic and nonhematopoietic progenitor cells, but it synergistically increases the activity of other hematopoietic growth factors, such as G-CSF, GM-CSF, and EPO. SCF stimulates the generation of dendritic cells in vitro and mast cells in vivo. [Pg.580]

Parallel to orchestrating acute inflammatory processes by providing an optimal milieu of cytokines, mediators, and adhesion molecules in order to recruit and activate effector cells to the site of infection, dendritic cells also setve as professional antigen-presenting cells for cells of the adaptive immune system ( antigen presentation ...

In the specialized environment of secondary lymphoid tissues such as lymph nodes or spleen, dendritic cells provide the requirements for naive T-lymphocytes to become activated and to proliferate. The professional antigen-presenting cells present peptides in MHC II, express costimulatory molecules, and release cytokines into the immunological synapse, which is formed by the antigen-presenting cell and the naive T-lymphocyte. Thus, cells of innate immunity initiate and facilitate the activation of naive lymphocytes, and it is easily conceivable that their cytokines and adhesion molecules will instruct the naive T-lymphocyte during activation and differentiation to T-effector cells.

An additional pathway leading to very efficient EFN-(3 responses involves one of the Toll-like-recqDtors (TLR), TLR3 which also senses dsRNA and is mainly expressed in dendritic cells (DC) and macrophages. Signal transduction then proceeds via the adaptor molecule TICAM/TRIF associated with the TER.-domain of... [Pg.639]

NF-kB regulates both innate and adaptive immune responses ( immune defense) [2]. Understanding the function of NF-kB in the development, maintenance, and activation of cells from the immune system (including hematopoietic cells, macrophages, dendritic cells, B and T lymphocytes) has greatly benefited from the analysis of knockout mice in which individual NF-kB family members were defective. [Pg.886]

TAK-1 can also activate c-jun N-terminal kinase ( JNK) andp38 both of which are MAP kinases. JNK activates the transcription factor AP-1 and p38 is involved in mRNA stabilisation. This pathway is also capable of activating ERF-7 in dendritic cells in response to TLR-7 and TLR-9 ligands. [Pg.1209]
