Cytochalasin B triggers a novel pertussis toxin sensitive pathway in TNF-alpha primed neutrophils

BMC Cell Biology, 2004
Background Cytochalasin B does not directly activate the oxygen-radical-producing NADPH oxidase activity of neutrophils but transfers desensitized G-protein coupled receptors (GPCR) into an active signaling state by uncoupling GCPR from the cytoskeleton.

Biased perspectives on formyl peptide receptors

Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2019
The innate immune system is the first line of defense against pathogenic threats. For the early pathogen recognition and activation of cell protective mechanisms, germline-encoded pattern recognition receptors (PRRs) detect characteristic and evolutionary conserved pathogen-associated molecular patterns (PAMPs).

Formyl Peptide Receptor 1 and 2 Dual Agonist Inhibits Human Neutrophil Chemotaxis by the Induction of Chemoattractant Receptor Cross-desensitization

Journal of Pharmacological Sciences, 2011
Formyl peptide receptor 1 (FPR1) and FPR2/ALX are known to control neutrophil chemotaxis in response to various ligands. In this study, we investigated the inhibitory mechanism of compound 43 (Cpd43), an FPR1 and FPR2/ALX dual agonist, on human ...

Formyl peptide receptor as a novel therapeutic target for anxiety-related disorders. [PDF]

PLoS ONE, 2014
Formyl peptide receptors (FPR) belong to a family of sensors of the immune system that detect microbe-associated molecules and inform various cellular and sensorial mechanisms to the presence of pathogens in the host.

Pyridinone Derivatives as Interesting Formyl Peptide Receptor (FPR) Agonists for the Treatment of Rheumatoid Arthritis

Molecules, 2021
Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by joint inflammation, cartilage damage and bone destruction. Although the pharmacological treatment of RA has evolved over the last few years, the new drugs have serious side ...

Preservation of Post-Infarction Cardiac Structure and Function via Long-Term Oral Formyl Peptide Receptor Agonist Treatment

JACC: Basic to Translational Science, 2019
Summary: Dysregulated inflammation following myocardial infarction (MI) promotes left ventricular (LV) remodeling and loss of function. Targeting inflammation resolution by activating formyl peptide receptors (FPRs) may limit adverse remodeling and ...

Structural Requirements for Molecular Recognition by fMLP Analogs Receptors: Comparative Conformational Analysis of (for-Met-Leu-Phe- OMe) and its Thioamide Analog (for-Met-Leuψ[CSNH]Phe-OMe)

Acta Chimica Slovenica, 2018
In order to determine the structural requirements of fMLP analogs receptors, this work presents the results of a comparative conformational analysis of the active chemotactic peptide (formyl-Met-Leu-Phe-OMe) and its inactive analog (formyl-Met-Leuψ [CSNH]

Expression and Signaling of Formyl-Peptide Receptors in the Brain

Neurochemical Research, 2010
The human formyl-peptide receptor (FPR) and its variants FPRL1 and FPRL2 belong to the G-protein coupled seven transmembrane receptor (GPCR) family sensitive to pertussis toxin. FPR and FPRL1 were first detected in phagocytic leukocytes, and FPRL2 was found in monocytes and in dendritic cells.

Differential activation of polymorphisms of the formyl peptide receptor by formyl peptides

Biochimica et Biophysica Acta (BBA) - Molecular Basis of Disease, 2007
We have investigated the role of two polymorphic sites (R190W and N192K) on the binding and activation of the formyl peptide receptor (FPR) by viral and formyl peptides. WEDWVGWI, a peptide with antiviral activity derived from the membrane proximal region of feline immunodeficiency virus, binds with high affinity to FPR.

Mycobacteria attenuate nociceptive responses by formyl peptide receptor triggered opioid peptide release from neutrophils. [PDF]

PLoS Pathogens, 2009
In inflammation, pain is regulated by a balance of pro- and analgesic mediators. Analgesic mediators include opioid peptides which are secreted by neutrophils at the site of inflammation, leading to activation of opioid receptors on peripheral sensory ...
