    October 2022 Keratinocyte-derived defensins activate neutrophil-specific receptors Mrgpra2a/b to prevent This signaling axis was required for effective neutrophil-mediated skin immunity and microbiome homeostasis Defensins and Mrgpra2 were critical for combating S. aureus infections and the formation of neutrophil Activation of Mrgpra2 by defensin triggered neutrophil release of IL-1β and CXCL2 which are vital for This study demonstrated the importance of epithelial-neutrophil signaling via the defensin-Mrgpra2 axis

  • GRK2 selectively attenuates the neutrophil NADPH-oxidase response triggered by β-arrestin recruiting

    August 2022 GRK2 selectively attenuates the neutrophil NADPH-oxidase response triggered by β-arrestin recruiting GPR84 agonists "In order to avoid a prolonged pro-inflammatory neutrophil response, signaling chain fatty acid receptor GPR84 as well as formyl peptide receptor 2 (FPR2), receptors expressed in neutrophils In this study, we investigated the effects of GRK2 inhibitors on neutrophil functions induced by GPR84 GRK2 was shown to be expressed in human neutrophils and analysis of subcellular fractions revealed a

  • Platelets in the NETworks interweaving inflammation and thrombosis

    Additionally, platelet interactions with neutrophils enhance neutrophil activation and are often crucial In particular, platelets can activate neutrophils to form neutrophil extracellular traps (NETs). This specific neutrophil effector function is characterized by neutrophils expelling chromatin fibres Here, virus infiltration may lead to a cytokine storm that potently activates neutrophils and leads to massive neutrophil infiltration into the lung and NET formation.

  • A GPCR-neuropeptide axis dampens hyperactive neutrophils by promoting an alternative-like polarization during bacterial infection

    by promoting an alternative-like polarization during bacterial infection Published date February 13, regulator of neutrophil bactericidal functions. Specifically, the Mrgpra1-NPFF axis counter-regulated interferon (IFN) γ-mediated neutrophil polarization during acute lung infection by favoring an alternative-like polarization, suggesting that it may act polarization , neutrophils .

  • Neutrophils are itching to specialize

    < GPCR News < GPCRs in Oncology and Immunology Neutrophils are itching to specialize Published date February 13, 2024 Abstract "Neutrophils are heterogeneous, but the mechanisms underlying their ability to polarize demonstrate that the GPCR Mrgpra1 and the neuropeptide NPFF, molecules involved in pain and itch, direct neutrophil polarization that impacts host defense and pneumonia susceptibility."

  • G Protein-coupled Receptor-mediated Membrane Targeting of PLCγ2 is Essential for Neutrophil Chemotaxis

    Oncology and Immunology G Protein-coupled Receptor-mediated Membrane Targeting of PLCγ2 is Essential for Neutrophil recruitment of PLCγ2 constitutes GPCR-mediated phospholipase C (PLC) signaling and is essential for neutrophil polarization and migration during chemotaxis. and cofilin activation; impaired dynamics of actin polymerization; and consequently, defects in cell polarization Tags G protein-coupled receptor (GPCR) , calcium-promoted Ras inactivator (CAPRI) , chemotaxis , neutrophils
