Probenecid directly impairs activation of the canine P2X7 receptor

Lysosomal Functions and Stimulates the The Activation of P2X7 Receptor Impairs

Activation 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...

P2X7 Receptor Activation Impairs Exogenous MHC Class I Oligopeptides Presentation in Antigen Presenting Cells

Major histocompatibility complex class I (MHC I) on antigen presenting cells (APCs) is a potent molecule to activate CD8(+) T cells and initiate immunity. P2X7 receptors (P2X7Rs) are present on the plasma membrane of APCs to sense the extracellular danger signal adenosine-5'-triphosphate (ATP). P2X7R activates the inflammasome and the release of IL-1β in macrophages and other immune cells to in...

O 4: Kynurenine Impairs MbMEC Function in Vitro Through Arylhydrocarbon Receptor Activation

In the development of neuroinflammatory diseases, alterations of the blood brain barrier (BBB) represent key events. The integrity of the BBB is partially maintained by endothelia cells (ECs), since they actively limit the transmigration of immune cells. However, the factors that cause endothelial cells to develop an immune cell-permissive phenotype are poorly understood. In general, it has bee...

Human P2X7 receptor activation induces the rapid shedding of CXCL16.

Activation of the purinergic P2X7 receptor by extracellular ATP induces the shedding of cell-surface molecules including the low-affinity IgE receptor, CD23 from leukocytes. CD23 is a known substrate of a disintegrin and metalloprotease (ADAM)10. The aim of the current study was to determine if P2X7 activation induced the shedding of the chemokine CXCL16, an ADAM10 substrate. Using immunolabell...
