Megjegyzések:Neutrophil extracellular trap (NET) ejected from activated dying neutrophils is a highly ordered structure of DNA and selected proteins capable to eliminate pathogenic microorganisms. Biochemical determinants of the non-randomly formed stable NETs have not been revealed so far. Studying the formation of human NETs we have observed that polyamines were incorporated into the NET. Inhibition of myeloperoxidase, which is essential for NET formation and can generate reactive chlorinated polyamines through hypochlorous acid, decreased polyamine incorporation. Addition of exogenous primary amines that similarly to polyamines inhibit reactions catalyzed by the protein cross-linker transglutaminases (TGases) has similar effect. Proteomic analysis of the highly reproducible pattern of NET components revealed cross-linking of NET proteins through chlorinated polyamines and epsilon(gamma-glutamyl) lysine as well as bis-gamma-glutamyl polyamine bonds catalyzed by the TGases detected in neutrophils. Competitive inhibition of protein cross-linking by monoamines disturbed the cross-linking pattern of NET proteins, which resulted in the loss of the ordered structure of the NET and significantly reduced capacity to trap bacteria. Our findings provide explanation of how NETs are formed in a reproducible and ordered manner to efficiently neutralize microorganisms at the first defense line of the innate immune system.

Cím:Analysis of the protein crosslink-profile changes and the neutrophil extracellular trap patterns elicited by different stimuli / Bernadett Márkus, Endre Kristóf, István Csomós, László Fésüs, Éva Csősz
Dátum:2017
Megjegyzések:Mature neutrophils act as a first line of defence migrating to the site of infection in response to microbial invasion. They are able to attack pathogen directly in three different ways: phagocytosis, release of antimicrobial peptides and formation of neutrophil extracellular traps (NETs). NET is the result of a unique form of cell death in which neutrophils eject their mixture of nucleoplasm and cytoplasm into the extracellular space forming a web-like structure. Hereby the invaded pathogens are trapped, neutralized therefore their dissemination is inhibited. Several antimicrobial proteins and proteases (such as neutrophil elastase, myeloperoxidase, cathepsin G, azurocidin, lactoferrin) are essential elements of the NET contributing to direct and indirect antimicrobial activities. Based on MS/MS data of protein cross-links formed in the differently treated NETs we could observe protein cross-linking by chlorinated polyamines and transglutaminases and we could demonstrate that both myeloperoxidase and TG1 are required for the stabilization of NET (Csomos et al. Cell Death Dis. 2016). Various bacteria, fungi and viruses can induce NET formation therefore we aimed to investigate the changes in the protein crosslink-profile and in the complex web-like structure during NET formation elicited by different pathogens.

Megjegyzések:White adipocytes contribute to energy storage accumulating lipid droplets, whereas brown and beige adipocytes mainly function in dissipating energy as heat primarily via the action of uncoupling protein 1 (UCP1). Bone morphogenic protein 7 (BMP7) was shown to drive brown adipocyte differentiation in murine interscapular adipose tissue. Here, we performed global RNA-sequencing and functional assays on adipocytes obtained from subcutaneous (SC) and deep-neck (DN) depots of human neck and differentiated with or without BMP7. We found that BMP7 did not influence differentiation but upregulated browning markers, including UCP1 mRNA and protein in SC and DN derived adipocytes. BMP7 also enhanced mitochondrial DNA content, levels of oxidative phosphorylation complex subunits, along with PGC1? and p-CREB upregulation, and fragmentation of mitochondria. Furthermore, both UCP1-dependent proton leak and UCP1-independent, creatine driven substrate cycle coupled thermogenesis were augmented upon BMP7 addition. The gene expression analysis shed light also on possible role of genes unrelated to thermogenesis so far, including ACAN, CRYAB, and ID1, which were amongst the highest upregulated ones by BMP7 treatment in both types of adipocytes. Together, our study shows that BMP7 strongly upregulates thermogenesis in human neck area derived adipocytes, along with genes, which might have a supporting role in energy expenditure.

Cím:Irisin stimulates the release of CXCL1 from differentiating human subcutaneous and deep-neck derived adipocytes via upregulation of NF[kappa]B pathway / Abhirup Shaw, Beáta B.

Megjegyzések:Thermogenic brown and beige adipocytes might open up new strategies in combating obesity. Recent studies in rodents and humans have indicated that these adipocytes release cytokines, termed "batokines". Irisin was discovered as a polypeptide regulator of beige adipocytes released by myocytes, primarily during exercise. We performed global RNA sequencing on adipocytes derived from human subcutaneous and deep-neck precursors, which were differentiated in the presence or absence of irisin. Irisin did not exert an effect on the expression of characteristic thermogenic genes, while upregulated genes belonging to various cytokine signaling pathways. Out of the several upregulated cytokines, CXCL1, the highest upregulated, was released throughout the entire differentiation period, and predominantly by differentiated adipocytes. Deep-neck area tissue biopsies also showed a significant release of CXCL1 during 24 hours irisin treatment. Gene expression data indicated upregulation of the NF?B pathway upon irisin treatment, which was validated by an increase of p50 and decrease of I?B? protein level, respectively. Continuous blocking of the NF?B pathway, using a cell permeable inhibitor of NF?B nuclear translocation, significantly reduced CXCL1 release. The released CXCL1 exerted a positive effect on the adhesion of endothelial cells. Together, our findings demonstrate that irisin stimulates the release of a novel adipokine, CXCL1, via upregulation of NF?B pathway in neck area derived adipocytes, which might play an important role in improving tissue vascularization.

Cím:Mitophagy is downregulated upon thermogenic stimulus in human beige adipocytes / Shaw Abhirup, Szatmári-Tóth Mária, Csomós István, Mocsár Gábor, Balajthy Zoltán, Győry Ferenc, Kristóf Endre Károly, Fésüs László

Megjegyzések:Adipocytes are classi?ed into white, brown and beige. Brown and beige adipocytes are important targets to combat obesity, as they are capable to dissipate energy in the form of heat, while the white adipocytes are primarily for energy storage. UCP1, an inner mitochondrial membrane protein mediates thermogenesis by uncoupling the mitochondrial respiratory chain from ATP synthesis. Hence, mitochondria are important for the thermogenic and metabolic functions of adipocytes. UCP1+ mitochondria in human adipocytes are mostly fragmented (Pisani et al, 2017). Mitophagy plays a vital role in beige to white adipocyte transition in mouse (Altshuler-Keylin et al, 2016). We intend to characterize the role of mitophagy in the thermogenic activation of primary human abdominal subcutaneous adipocytes and SGBS cells. Isolated preadipocytes were differentiated into white and browning adipocytes, which were treated with dibutyryl-cAMP (6, 10 and 14 hours). Genes related to parkin-dependent and independent mitophagy were downregulated upon thermogenic stimulus; the parkin dependent ones being the most downregulated. The lipidated form of LC3, LC3-II is recruited on the outer membrane of the autophagosome which indicates ongoing autophagy. TOM20 is an outer mitochondrial membrane protein and marks the mitochondria. LC3 and TOM20 immunostaining were performed, followed by quanti?cation of LC3 punctae,which was high in untreated control adipocytes but decreased signi?cantly upon thermogenic stimulus, suggesting repressed autophagy/mitophagy. Colocalization of TOM20 and LC3 can indicate mitophagy. Decreased colocalization was observed upon thermogenic stimulus, which further proved repressed mitophagy.TOM20 quanti?cation showed increased number of fragmented mitochondria upon thermogenic stimulus suggesting prompt inhibition of mitophagy, thereby protecting many fragmented mitochondria from degradation and boosting thermogenesis.

Cím:Thermogenic Activation Downregulates High Mitophagy Rate in Human Masked and Mature Beige Adipocytes / Mária Szatmári-Tóth, Abhirup Shaw, István Csomós, Gábor Mocsár, Pamela Fischer-Posovszky, Martin Wabitsch, Zoltán Balajthy, Cecília Lányi, Ferenc Győry, Endre Kristóf, László Fésüs

Megjegyzések:Thermogenic brown and beige adipocytes oxidize metabolic substrates producing heat, mainly by the mitochondrial uncoupling protein UCP1, and can thus counteract obesity. Masked beige adipocytes possess white adipocyte-like morphology, but can be made thermogenic by adrenergic stimuli. We investigated the regulation of mitophagy upon thermogenic activation of human masked and mature beige adipocytes. Human primary abdominal subcutaneous adipose-derived stromal cells (hASCs) and SGBS preadipocytes were differentiated to white and beige adipocytes, then their cAMP-induced thermogenic potential was assessed by detecting increased expressions of UCP1, mitochondrial DNA content and respiratory chain complex subunits. cAMP increased the thermogenic potential of white adipocytes similarly to beige ones, indicating the presence of a masked beige population. In unstimulated conditions, a high autophagic flux and mitophagy rates (demonstrated by LC3 punctae and TOM20 co-immunostaining) were observed in white adipocytes, while these were lower in beige adipocytes. Silencing and gene expression experiments showed that the ongoing mitophagy was Parkin-independent. cAMP treatment led to the downregulation of mitophagy through PKA in both types of adipocytes, resulting in more fragmented mitochondria and increased UCP1 levels. Our data indicates that mitophagy is repressed upon encountering a short-term adrenergic stimulus, as a fast regulatory mechanism to provide high mitochondrial content for thermogenesis.

Megjegyzések:White adipocytes store lipids, have a large lipid droplet and few mitochondria. Brown and beige adipocytes, which produce heat, are characterized by high expression of uncoupling protein (UCP) 1, multilocular lipid droplets, and large amounts of mitochondria. The rs1421085 T-to-C single-nucleotide polymorphism (SNP) of the human FTO gene interrupts a conserved motif for ARID5B repressor, resulting in adipocyte type shift from beige to white. We obtained abdominal subcutaneous adipose tissue from donors carrying FTO rs1421085 TT (risk-free) or CC (obesity-risk) genotypes, isolated and differentiated their preadipocytes into beige adipocytes (driven by the PPAR? agonist rosiglitazone for 14 days), and activated them with dibutyryl-cAMP for 4 hours. Then, either the same culture conditions were applied for additional 14 days (active beige adipocytes) or it was replaced by a white differentiation medium (inactive beige adipocytes). White adipocytes were differentiated by their medium for 28 days. RNA-sequencing was performed to investigate the gene expression pattern of adipocytes carrying different FTO alleles and found that active beige adipocytes had higher brown adipocyte content and browning capacity compared to white or inactive beige ones when the cells were obtained from risk-free TT but not from obesity-risk CC genotype carriers. Active beige adipocytes carrying FTO CC had lower thermogenic gene (e.g., UCP1, PM20D1, CIDEA) expression and thermogenesis measured by proton leak respiration as compared to TT carriers. In addition, active beige adipocytes with CC alleles exerted lower expression of ASC-1 neutral amino acid transporter (encoded by SLC7A10) and less consumption of Ala, Ser, Cys, and Gly as compared to risk-free carriers. We did not observe any influence of the FTO rs1421085 SNP on white and inactive beige adipocytes highlighting its exclusive and critical effect when adipocytes were activated for thermogenesis.

Cím:Mitophagy Mediates the Beige to White Transition of Human Primary Subcutaneous Adipocytes Ex Vivo / Vámos Attila, Shaw Abhirup, Varga Klára, Csomós István, Mocsár Gábor, Balajthy Zoltán, Lányi Cecília, Bacso Zsolt, Szatmári-Tóth Mária, Kristóf Endre

Megjegyzések:Brown and beige adipocytes have multilocular lipid droplets, express uncoupling protein (UCP) 1, and promote energy expenditure. In rodents, when the stimulus of browning subsides, parkin-dependent mitophagy is activated and dormant beige adipocytes persist. In humans, however, the molecular events during the beige to white transition have not been studied in detail. In this study, human primary subcutaneous abdominal preadipocytes were differentiated to beige for 14 days, then either the beige culture conditions were applied for an additional 14 days or it was replaced by a white medium. Control white adipocytes were differentiated by their specific cocktail for 28 days. Peroxisome proliferator-activated receptor ?-driven beige differentiation resulted in increased mitochondrial biogenesis, UCP1 expression, fragmentation, and respiration as compared to white. Morphology, UCP1 content, mitochondrial fragmentation, and basal respiration of the adipocytes that underwent transition, along with the induction of mitophagy, were similar to control white adipocytes. However, white converted beige adipocytes had a stronger responsiveness to dibutyril-cAMP, which mimics adrenergic stimulus, than the control white ones. Gene expression patterns showed that the removal of mitochondria in transitioning adipocytes may involve both parkin-dependent and -independent pathways. Preventing the entry of beige adipocytes into white transition can be a feasible way to maintain elevated thermogenesis and energy expenditure.
