anti-G Protein-Coupled Receptor MRGX2 (MRGPRX2) Anticorps

Human G Protein-Coupled Receptor MRGX2 (MRGPRX2) interaction partners

1. Low levels of MRGPRX2 were detected in non-asthma lung mast cells, but its expression was significantly up-regulated in asthma lung mast cells.

2. the present study demonstrates that FceRI and MRGPRX2 function can be inversely regulated by SCF in an acute scenario, suggesting that the signaling requirements differ profoundly between the routes.

3. The authors discuss the possibility that MRGPRX2 responds to various as-yet-unidentified endogenous ligands that have specific characteristics, and propose that MRGPRX2 plays an important role in regulating inflammatory responses to endogenous harmful stimuli, such as protein breakdown products released from damaged or dying cells.

4. these peptides are identified as fragments of albumin. The isolated fragments activate MRGPRX2 and degranulate MRGPRX2 expressing LAD 2 cells in dose-dependent manner. The isolated basic peptides generated from human albumin are able to degranulate mast cells via the MRGPRX2.

5. The results showed a kind of mechanism that sinomenine-induced anaphylactoid reactions were mediated by MRGPRX2 via activating PLC molecular signaling pathways to provoke mast cells Ca(2+) mobilization and degranulation.

6. data suggest that mast cells play important roles in both gingival homeostasis and periodontal disease by orchestrating an interaction between gingival epithelial cells and neutrophils via MRGPRX2-mediated degranulation

7. MRGX2 is related to nociception, adrenal gland secretion and mast cell degranulation. (Review)

8. contributes to larger and longer lasting wheal reactions to intradermally injected neuropeptides in patients with chronic urticaria

9. Ectopic expression of MrgX2 in rat basophilic leukemia RBL-2H3 cells and murine bone marrow mast cells renders these cells responsive to human beta-defensin for degranulation.

10. identified MrgX2 as a novel G protein-coupled receptor for the antibacterial peptide LL-37 and demonstrated that unlike most G protein-coupled receptors it is resistant to agonist-induced receptor phosphorylation, desensitization, and internalization.

11. cortistatin-14 shown to be a high affinity ligand for G protein coupled receptor MrgX2 which is expressed in dorsal root ganglion

12. MRGX2 amino acid substitutions may alter the interactions between MRGX2 protein and its ligand, thus, potentially led to adaptive changes of the pain-perception-related nervous system during human evolution.

13. Mas, MrgD, and MRG mediated Ang IV-stimulated AA release that was highest for Mas. While Ang III activated Mas and MrgX2, Ang II stimulated AA release via Mas and MRG.
