This study investigated the expression of intercellular adhesion molecule-1, a leukocyte adhesion molecule, on cultured rat hepatic sinusoidal endothelial cells during stimulation with tumor necrosis factor-alpha or interleukin-1 alpha. Using immunoelectron microscopy and the immunogold technique against intercellular adhesion molecule-1, gold particles were shown to increase significantly on the surface of sinusoidal epithelial cells treated with tumor necrosis factor-alpha (100 U/ml) or interleukin-1 alpha (10 U/ml) for 8 h compared with unstimulated cells. In addition, semi-quantitative analysis of intercellular adhesion molecule-1 on the sinusoidal endothelial cells was performed by cytofluorometer. Even without stimulation, intercellular adhesion molecule-1 was weakly expressed. However, 8 h after tumor necrosis factor-alpha or interleukin-1 alpha treatment, the expression of intercellular adhesion molecule-1 on cells was increased in a dose-dependent manner. Kinetic analysis showed that the expression of intercellular adhesion molecule-1 on sinusoidal endothelial cells treated with these cytokines increased gradually from the beginning of stimulation to 24 h. These findings suggest that hepatic sinusoidal endothelial cells may mediate the direct interaction between leukocytes and sinusoidal endothelial cells by expressing leukocyte adhesion molecules such as intercellular adhesion molecule-1.

D007375 Interleukin-1 A soluble factor produced by MONOCYTES; MACROPHAGES, and other cells which activates T-lymphocytes and potentiates their response to mitogens or antigens. Interleukin-1 is a general term refers to either of the two distinct proteins, INTERLEUKIN-1ALPHA and INTERLEUKIN-1BETA. The biological effects of IL-1 include the ability to replace macrophage requirements for T-cell activation.

D005434 Flow Cytometry Technique using an instrument system for making, processing, and displaying one or more measurements on individual cells obtained from a cell suspension. Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.
