Reticular cells

Krenacs, T Uda, H., and Tanaka, S. (1991) One-step double immunolabeling of mouse interdigitating reticular cells simultaneous applications of preformed complexes of monoclonal rat antibody Ml 8 with horseradish peroxidase-linked antirat immunoglobulin and of monoclonal mouse antila antibody with alkaline phosphatase coupled antimouse immunoglobulins. J. Histochem. Cytochem. 39, 1719-1723. 

In contrast, in the small intestine (Figure 3.15), the mucosa is composed of surface projections or villi with a core of lamina propria and muscle fibers. In the lamina propria itself are found intestinal glands, fine connective tissues, reticular cells, and lymphatic tissue. The submucosa is filled with glands in the duodenum whereas in the muscularis externa an inner circular layer and an outer longitudinal layer of muscle are present. Parasym-... 

Fibroblastic reticular cells (FRCs) constitute the main stromal population and form its internal three-dimensional network. FRCs express surface molecules and produce homing chemokines for T cells, B cells, and DCs. FRCs provide anatomical airangements that influence the riaffic patterns of lymphocytes facilitating lymphocyte crawling along pre-... 

This condition—which has also been known under the names of reticulum cell leukemia, lymphoid reticular cell neoplasia, and hairy cell disease (M8)—is characterized by massive splenomegaly... 

L-(-f-)-Tartrate (0.05 M) inhibited isoenzymes Nos. 1-4 but had no appreciable effect on the reticular cell isoenzyme. No. 5 (M8, Yl). In cytochemical studies of blood smears from three patients with leukemic reticuloendotheliosis, the acid phosphatase activity in the monocytes, eosinophiles, neutrophiles, and other cells that could definitely be identified as lymphocytes did not differ appreciably from those of normal subjects. In all three patients the neoplastic reticulum cell showed various degrees of acid phosphatase activity most of them were strongly positive. The enzyme activity in these cells was resistant to to l-( + )-tartrate, whereas it was completely inhibited in other types of cells. 

In the most primitive situation, such as that found in the sinusoidal beds of the liver, adrenal cortex, and pituitary, a reticular fiber and a reticular cell are interposed between the parenchymal cell and the blood. In most areas, however, the loose connective tissue is the material through which diffusion between the vascular and parenchymal compartments must take place. Thus ions, nutritive substances, oxygen, water, and the like must pass through this layer of tissue to the cells and in reverse the metabolites, secretions of the parenchymal cells, are delivered through this material into the blood. It is precisely in this compartment, this interstitial layer, that inflammation takes place. 

The hypothesis that skin had its own associated immnne system was proposed in 1978 by Streilein [29] and denominated SALT. By this concept the skin is provided evolutionarily with a specialized set of recircnlating and migratory lymph-reticular cells, organized, draining lymphoid organs, and a responsive dermal microvasculature. 

A small amount of /3-glucuroiiidase has been found in some thymus lymphoid cells, but a strong reaction was obsen ed in the peripheral portion of the spleen s marginal zone and in the reticular cells of other tissue (Pearson et al., 1967a). 

The ellipsoids temfinate in arterioles with a narrow lumen that runs through a sheath of reticular fibres, reticular cells and macrophages, the ellipsoid. Ellipsoids appear to have a specialized function for plasma...
