The Two Formyl Peptide Receptors Differently Regulate GPR84-Mediated Neutrophil NADPH Oxidase Activity [PDF]

open access: yesJournal of Innate Immunity, 2021
Neutrophils express the two formyl peptide receptors (FPR1 and FPR2) and the medium-chain fatty acid receptor GPR84. The FPRs are known to define a hierarchy among neutrophil G protein-coupled receptors (GPCRs), that is, the activated FPRs can either ...

The N-Formyl Peptide Receptors and Rheumatoid Arthritis: A Dangerous Liaison or Confusing Relationship? [PDF]

open access: yesFrontiers in Immunology, 2021
Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by a progressive symmetric inflammation of the joints resulting in bone erosion and cartilage destruction with a progressive loss of function and joint deformity. An increased number

The N-formyl peptide receptors: contemporary roles in neuronal function and dysfunction [PDF]

open access: yesNeural Regeneration Research, 2020
N-formyl peptide receptors (FPRs) were first identified upon phagocytic leukocytes, but more than four decades of research has unearthed a plethora of non-myeloid roles for this receptor family.

Fragments of viral surface proteins modulate innate immune responses via formyl peptide receptors [PDF]

open access: yesiScience
Summary: Formyl peptide receptors (FPRs) are pattern recognition receptors well-known for bacterial pathogen sensing. We here identified activator and inhibitor motifs for FPRs that are present on surface proteins of various viral pathogens.

Inhibition of formyl peptide receptors improves the outcome in a mouse model of Alzheimer disease [PDF]

open access: yesJournal of Neuroinflammation, 2020
Background An important hallmark of Alzheimer’s disease (AD) is the increase of Aβ1-42 burden and its accumulation to senile plaques, leading the reactive gliosis and neurodegeneration.

Biological Role of the N-Formyl Peptide Receptors

open access: yesImmunopharmacology and Immunotoxicology, 2006
Ligation of N-formyl-methionyl-leucyl-phenylalanine (fMLP) to its specific cell surface receptors triggers different cascades of biochemical events, eventually leading to cellular activation. The formyl peptide receptors (FPRs) are members of the seven-transmembrane, G-protein coupled receptors superfamily, expressed at high levels on polymorphonuclear

Walker 256 Tumor Growth Suppression by Crotoxin Involves Formyl Peptide Receptors and Lipoxin A4 [PDF]

open access: yesMediators of Inflammation, 2016
We investigated the effects of Crotoxin (CTX), the main toxin of South American rattlesnake (Crotalus durissus terrificus) venom, on Walker 256 tumor growth, the pain symptoms associated (hyperalgesia and allodynia), and participation of endogenous ...

Bioactive Compounds as Modulators of N-Formyl Peptide Signaling in Chronic Diseases [PDF]

open access: yesMolecules
In physiological situations involving cell damage, molecules derived from mitochondria or bacteria are produced. These molecules are known as N-formyl peptides and are detected by formyl peptide receptors (FPRs), which stimulate immune cells to migrate ...

The N-formyl peptide receptors and the anaphylatoxin C5a receptors: An overview

open access: yesBiochimie, 2007
Leukocyte recruitment to sites of inflammation and infection is dependent on the presence of a gradient of locally produced chemotactic factors. This review is focused on current knowledge about the activation and regulation of chemoattractant receptors.

NEW FORMYL PEPTIDE HAS THE STIMULATING PROPERTIES IN POINT OF IMMUNE SYSTEM CELLS [PDF]

open access: yesAnnals of Mechnikov's Institute, 2017
Introduction Tuberculosis infection (TBI) is still one of the major health problems, despite of global intensive medical and pharmaceutical efforts as it is known, in the majority of immunocompetent individuals TBI is repressed by immune system, and as a
