Commensal-Epithelial Signaling Mediated via Formyl Peptide Receptors [PDF]

The American Journal of Pathology, 2010
Commensal bacteria and/or their products engender beneficial effects to the mammalian gut, including stimulating physiological cellular turnover and enhancing wound healing, without activating overt inflammation. In the present study, we observed commensal bacteria-mediated activation of the noninflammatory extracellular signal-regulated kinase[ERK ...

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 ...

Targeting neuroinflammation in Alzheimer’s disease [PDF]

, 2016
Almost 47 million people suffer from dementia worldwide, with an estimated new case diagnosed every 3.2 seconds. Alzheimer’s disease (AD) accounts for approximately 60%–80% of all dementia cases. Given this evidence, it is clear dementia represents one

The formyl peptide fMLF primes platelet activation and augments thrombus formation [PDF]

, 2019
Formyl peptide receptors (FPRs) play pivotal roles in the regulation of innate immunity and host defence. FPRs include three family members; FPR1, FPR2/ALX and FPR3.

House dust mite allergen activates human eosinophilsviaformyl peptide receptor and formyl peptide receptor‐like 1 [PDF]

European Journal of Immunology, 2007
AbstractThe objective was to evaluate which receptors house dust mite (HDM) and birch pollen extracts engage to activate human eosinophils. Chemotaxis and degranulation were studied in eosinophils pretreated with pertussis toxin and other antagonists of G protein‐coupled receptors,e.g.the formyl peptide receptor (FPR), CC chemokine receptor 3 (CCR3 ...

Lipoxin-mediated signaling: ALX/FPR2 interaction and beyond

Pharmacological Research, 2023
In the aftermath of tissue injury or infection, an efficient resolution mechanism is crucial to allow tissue healing and preserve appropriate organ functioning. Pro-resolving bioactive lipids prevent uncontrolled inflammation and its consequences.

Smart, Bio‐Inspired Polymers and Bio‐Based Molecules Modified by Zwitterionic Motifs to Design Next‐Generation Materials for Medical Applications

Advanced Functional Materials, EarlyView.
Bio‐based and (semi‐)synthetic zwitterion‐modified novel materials and fully synthetic next‐generation alternatives show the importance of material design for different biomedical applications. The zwitterionic character affects the physiochemical behavior of the material and deepens the understanding of chemical interaction mechanisms within the ...

Lipoxin Receptors

The Scientific World Journal, 2007
Lipoxins (LXs) represent a class of arachidonic acid (AA) metabolites that carry potent immunoregulatory and anti-inflammatory properties, LXA4 and LXB4 being the main components of this series. LXs are generated by cooperation between 5-lipoxygenase (LO)

Microbiota-Produced N-Formyl Peptide fMLF Promotes Obesity-Induced Glucose Intolerance. [PDF]

, 2019
The composition of the gastrointestinal microbiota and associated metabolites changes dramatically with diet and the development of obesity. Although many correlations have been described, specific mechanistic links between these changes and glucose ...

Variable responses of formyl peptide receptor haplotypes toward bacterial peptides

Immunogenetics, 2008
The chemoattractant neutrophil formyl peptide receptor (FPR) binds bacterial and mitochondrial N-formylated peptides, which allows the neutrophils to find the bacterial source and/or site of tissue damage. Certain inflammatory disorders may be due in part to an impaired innate immune system that does not respond to acute bacterial damage in a timely ...
