Production of Interleukin-1 Inhibitors by the Murine Macrophage Cell Line P388D₁ Which Produces Interleukin-1

Murine Macrophage Interleukin-1 Release by Capsularlike

Calcium dependency of interleukin-1 secretion by a chicken macrophage cell line.

The role of calcium in transducing the signal for interleukin-1 (IL-1) secretion was examined in the MQ-NCSU chicken macrophage cell line. Cells were maintained in RPMI 1640 medium supplemented with 5% chicken serum and antibiotic-antimycotic solution at 40 C and 5% CO2. The effects of stimulation with lipopolysaccharide (LPS), calcium ionophore A23187, or a combination of both on IL-1 secretio...

Human monocyte production of interleukin-1: parameters of the induction of interleukin-1 secretion by lipopolysaccharides.

The role of lipopolysaccharide (LPS) as an activator of human monocyte interleukin-1 (IL-1) synthesis and secretion has been examined in this study. The results demonstrate that when blood monocytes are prepared under low endotoxin conditions, they do not spontaneously secrete IL-1 activity. When cells are exposed to LPS extracted from different bacterial species, there is variation seen in the...

monarch-1 activation in murine macrophage cell line (j774 a.1) infected with iranian strain of leishmania major.

background: leishmania major is an intracellular parasite transmitted through the bite of the female phlebotomine sand flies. leishmania major is able to escape the host immune defense and survive within macrophages. modulation of the nf-κb (nuclear factor-kappa b) activation and suppression of the pro-inflammatory cytokines by l. major are the main evasion mechanisms that remain to be explored...

Production of immune interferon by an interleukin 2-independent murine T cell line.

An interleukin 2-independent murine T cell line (BFS) was isolated that produced immune interferon after stimulation with phorbol 12-myristate 13-acetate. The BFS cell line did not produce detectable levels of interleukin 1, interleukin 2, B cell growth factor, macrophage-granulocyte colony-stimulating factor, macrophage-activating factor, or T cell replacing factor. Maximal interferon was indu...
