Identification of a monocyte specific pre-interleukin 1 beta convertase activity.

CASP 1 ( caspase 1 , apoptosis - related cysteine peptidase ( interleukin 1 , beta , convertase ) )

P106: Interleukin-1 Beta; A Forgotten Piece of MS Puzzle Target Therapy

Multiple sclerosis (MS) is an inflammatory autoimmune disease which is presented by environmental factors and genetic predisposition, increasingly affecting a large number of people worldwide. CNS inflammation is a local tissue response to stimulants and is characterized by induction of cytokines, chemokines and vascular permeability. Our goal in this study is to understand the micro-environmen...

Ethanol inhibits monocyte chemotactic protein-1 expression in interleukin-1{beta}-activated human endothelial cells.

The aim of this study was to determine the effect of ethanol (EtOH) on endothelial monocyte chemotactic protein-1 (MCP-1) expression. IL-1beta increased the production of MCP-1 by human umbilical vein endothelial cells from undetectable levels to approximately 900 pg/ml at 24 h. EtOH dose-dependently inhibited IL-1beta-stimulated MCP-1 secretion as determined by ELISA: 25 +/- 1%, 35 +/- 7%, and...

Lactoferrin decreases monocyte-induced fibroblast production of myeloid colony-stimulating activity by suppressing monocyte release of interleukin-1.

Lactoferrin (Lf) is a negative regulator of myelopoiesis which operates by suppressing the release from mononuclear phagocytes of GM colony-stimulating factor (GM-CSF) or monokines which can then induce the release of GM-CSA from accessory cells. In this study, endotoxin-depleted, purified iron-saturated human Lf was assessed for its effect on the production of interleukin-1 by cultured monocyt...

IL 1 B ( interleukin 1 , beta )

Other names: Catabolin; IL-1; IL-1B; IL1-BETA; IL1F2; pro-interleukin-1-beta HGNC (Hugo): IL1B Location: 2q13 Note: IL-1beta is a pro-inflamatory cytokine and is expressed by many cells including macrophage, NK cells, monocytes, and neutrophils. It belongs to the IL-1 family cluster that includes the IL-1a, and IL1-RN genes. The caspase 1 (CASP1/ICE) gene proteolitically activates IL-1β. This g...
