The P2X7 Receptor-Interleukin-1 Liaison
Interleukin-1β (IL-1β) plays a central role in stimulation of innate immune system and inflammation and in several chronic inflammatory diseases. These include rare hereditary conditions, e.g., auto-inflammatory syndromes, as well as common pathologies, such as type II diabetes, gout and atherosclerosis. A better understanding of IL-1β synthesis and release is particularly relevant for the desi...
متن کاملPannexin-1 mediates large pore formation and interleukin-1beta release by the ATP-gated P2X7 receptor.
P2X(7) receptors are ATP-gated cation channels; their activation in macrophage also leads to rapid opening of a membrane pore permeable to dyes such as ethidium, and to release of the pro-inflammatory cytokine, interleukin-1beta (IL-1beta). It has not been known what this dye-uptake path is, or whether it is involved in downstream signalling to IL-1beta release. Here, we identify pannexin-1, a ...
متن کاملInterleukin-1 receptor antagonist.
IL-1ra is the first described naturally occurring receptor antagonist of any cytokine or hormone-like molecule. IL-1ra is a member of the IL-1 family by three criteria: amino acid sequence homology of 26 to 30% to IL-1 beta and 19% to IL-1 alpha; similarities in gene structure; and common gene localization to human chromosome 2q14. Two structural variants of IL-1ra exist: sIL-1ra, a secretory m...
متن کاملActivation of the damage-associated molecular pattern receptor P2X7 induces interleukin-1β release from canine monocytes.
P2X7, a damage-associated molecular pattern receptor and adenosine 5'-triphosphate (ATP)-gated cation channel, plays an important role in the activation of the NALP3 inflammasome and subsequent release of interleukin (IL)-1β from human monocytes; however its role in monocytes from other species including the dog remains poorly defined. This study investigated the role of P2X7 in canine monocyte...
متن کاملCaveolin-1 regulates P2X7 receptor signaling in osteoblasts.
The synthesis of new bone in response to a novel applied mechanical load requires a complex series of cellular signaling events in osteoblasts and osteocytes. The activation of the purinergic receptor P2X(7)R is central to this mechanotransduction signaling cascade. Recently, P2X(7)R have been found to be associated with caveolae, a subset of lipid microdomains found in several cell types. Dele...
