Abstract
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. FPRs are expressed within neuronal tissues and markedly in the central nervous system, where FPR interactions with endogenous ligands have been implicated in the pathophysiology of several neurodegenerative diseases including Alzheimer's disease and Parkinson's disease, as well as neurological cancers such as neuroblastoma. Whilst the homeostatic function of FPRs in the nervous system is currently undefined, a variety of novel physiological roles for this receptor family in the neuronal context have been posited in both human and animal settings. Rapid developments in recent years have implicated FPRs in the process of neurogenesis and neuronal differentiation which, upon greater characterisation, could represent a novel pharmacological target for neuronal regeneration therapies that may be used in the treatment of brain/spinal cord injury, stroke and neurodegeneration. This review aims to summarize the recent progress made to determine the physiological role of FPRs in a neuronal setting, and to put forward a case for FPRs as a novel pharmacological target for conditions of the nervous system, and for their potential to open the door to novel neuronal regeneration therapies.

Aberrant DNA methylation levels of the formyl peptide receptor 1/2/3 genes are associated with obstructive sleep apnea and its clinical phenotypes. Am J Transl Res 2020; 12:2521-2537. [PMID: 32655788 PMCID: PMC7344102] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2019] [Accepted: 04/15/2020] [Indexed: 06/11/2023]
Abstract
BACKGROUND FPR1 over-expression and insufficiency of FPR2 and FPR3 are associated with disease severity of obstructive sleep apnea (OSA). We hypothesized that epigenetic modification of the FPR1/2/3 genes may underlie intermittent hypoxia with re-oxygenation (IHR) injury in OSA. METHODS DNA methylation levels over 17 CpG sites of the FPR1/2/3 genes and their gene expression levels in the peripheral blood mononuclear cells were determined in 40 treatment-naïve OSA patients, 12 severe OSA patients under long-term continuous positive airway pressure treatment, 16 primary snoring (PS) subjects, and 10 healthy non-snorers (HS). RESULTS Both -524 and -264 CpG sites of the FPR1 gene were hypomethylated in treatment-naïve OSA versus HS, while -264 CpG site methylation level was negatively correlated with FPR1/FPR3 gene expression ratio and associated with prevalent diabetes mellitus. Both +8802 and +8845 CpG sites of the FPR2 gene were hypermethylated in treatment-naive OSA versus HS, while hypermethylated +9132 and +9150 CpG sites were both associated with prevalent hypertension. FPR3 gene expression and DNA methylation levels over -842/-516 CpG sites of the FPR3 gene were both decreased in treatment-naive OSA versus HS, while hypermethylated -429 CpG site was associated with elevated serum C-reactive protein level. In vitro IHR stimuli in human monocytic THP-1 cells resulted in gene promoter hypomethylation-mediated FPR1 over-expression, increased production of reactive oxygen species, and increased cell apoptosis, which could be reversed with re-methylation agent, folic acid, treatment. CONCLUSIONS Aberrant DNA methylation patterns of the FPR1/2/3 gene promoters contribute to disease severity and diabetes mellitus or cardiovascular disease in OSA patients, probably through regulating FPR1/2/3 gene expressions.

Small molecule inhibition of cAMP response element binding protein in human acute myeloid leukemia cells. Leukemia 2016; 30:2302-2311. [PMID: 27211267 PMCID: PMC5143163 DOI: 10.1038/leu.2016.139] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2016] [Revised: 04/24/2016] [Accepted: 05/04/2016] [Indexed: 12/16/2022]
Abstract
The transcription factor CREB (cAMP Response-Element Binding Protein) is overexpressed in the majority of acute myeloid leukemia (AML) patients, and this is associated with a worse prognosis. Previous work revealed that CREB overexpression augmented AML cell growth, while CREB knockdown disrupted key AML cell functions in vitro. In contrast, CREB knockdown had no effect on long-term hematopoietic stem cell activity in mouse transduction/transplantation assays. Together, these studies position CREB as a promising drug target for AML. To test this concept, a small molecule inhibitor of CREB, XX-650-23, was developed. This molecule blocks a critical interaction between CREB and its required co-activator CBP (CREB Binding Protein), leading to disruption of CREB-driven gene expression. Inhibition of CBP-CREB interaction induced apoptosis and cell-cycle arrest in AML cells, and prolonged survival in vivo in mice injected with human AML cells. XX-650-23 had little toxicity on normal human hematopoietic cells and tissues in mice. To understand the mechanism of XX-650-23, we performed RNA-seq, ChIP-seq and Cytometry Time of Flight with human AML cells. Our results demonstrate that small molecule inhibition of CBP-CREB interaction mostly affects apoptotic, cell-cycle and survival pathways, which may represent a novel approach for AML therapy.

Abstract
Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are life-threatening, cutaneous adverse drug reactions that are accompanied by keratinocyte cell death. Dead keratinocytes from SJS/TEN lesions exhibited necrosis, by morphological criteria. Supernatant from peripheral blood mononuclear cells (PBMCs) that had been exposed to the causative drug from patients with SJS/TEN induced the death of SJS/TEN keratinocytes, whereas supernatant from PBMCs of patients with ordinary drug skin reactions (ODSRs) exposed to the same drug did not. Keratinocytes from ODSR patients or from healthy controls were unaffected by supernatant from SJS/TEN or ODSR PBMCs. Mass spectrometric analysis identified annexin A1 as a key mediator of keratinocyte death; depletion of annexin A1 by a specific antibody diminished supernatant cytotoxicity. The necroptosis-mediating complex of RIP1 and RIP3 was indispensable for SJS/TEN supernatant-induced keratinocyte death, and SJS/TEN keratinocytes expressed abundant formyl peptide receptor 1 (FPR1), the receptor for annexin A1, whereas control keratinocytes did not. Inhibition of necroptosis completely prevented SJS/TEN-like responses in a mouse model of SJS/TEN. Our results demonstrate that a necroptosis pathway, likely mediated by annexin 1 acting through the FPR1 receptor, contributes to SJS/TEN.

Abstract
The formyl peptide receptor 1 (FPR1) is mainly expressed by mammalian phagocytic leukocytes and plays a role in chemotaxis, killing of microorganisms through phagocytosis, and the generation of reactive oxygen species. A large number of ligands have been identified triggering FPR1 including formylated and non-formylated peptides of microbial and endogenous origin. While the expression of FPR1 in neutrophils has been investigated intensively, knowledge on the regulation of FPR1 expression in polarized macrophages is lacking. In this study we show that primary human neutrophils, monocytes and resting macrophages do express the receptor on their cell surface. Polarization of macrophages with IFNγ, LPS and with the TLR8 ligand 3M-002 further increases FPR1 mRNA levels but does not consistently increase protein expression or chemotaxis towards the FPR1 ligand fMLF. In contrast, polarization of primary human macrophages with IL-4 and IL-13 leading to the alternative activated macrophages, reduces FPR1 cell surface expression and abolishes chemotaxis towards fMLF. These results show that M2 macrophages will not react to triggering of FPR1, limiting the role for FPR1 to chemotaxis and superoxide production of resting and pro-inflammatory M1 macrophages.
